BodyMassIndex (bmi index) refers to the index obtained by dividing the kilograms of weight by the square of the meters of height, that is, the body mass index. It is a commonly used international standard to measure the degree of obesity and health, mainly for statistical purposes.

Bmi is an index closely related to body fat, which takes into account two factors: weight and height. Bmi is simple and practical, which can reflect the situation of overweight and obesity. It is more accurate to measure the risk of heart disease, hypertension and other diseases due to overweight than to identify them simply by weight.

Bmi was originally designed as a statistical tool for public health research. When we need to know whether obesity is the cause of a disease, we can convert the patient's height and weight into body mass index, and then find out whether there is a linear relationship between this value and the incidence.

However, with the development of science and technology, the current body mass index value is only a reference value. To truly measure whether a patient is obese, the body fat rate is more accurate than the body mass index, and the waist height is better than the body fat rate, but the best view is to look at visceral fat (if the visceral fat is normal, even if the waist circumference is large and the body fat rate is high, the health risk is not high, and many Japanese sumo wrestlers use this fat method).

Therefore, the role of bmi has gradually changed, from medical use to the weight loss index of the general public. Bmi is the abbreviation of BodyMassIndex, which means "body mass index" in Chinese. It is calculated according to your height and weight. Bmi is an internationally recognized grading method for evaluating the degree of obesity, and the World Health Organization (WHO) also uses bmi to define obesity or overweight.

2. What is the unemployment rate index in China?

The unemployment rate announced by the accounting department is the registered unemployment rate in cities and towns, that is, the number of registered workers in cities and towns and the registered unemployment rate in cities and towns. It refers to the number of unemployed workers who meet all the employment conditions in a certain period of time, aiming at measuring the productivity of idle labor and is the main indicator reflecting the unemployment situation in a country or region.

3. What do you mean by EPSPEPB of stock?

What does the EPSPEPB of the stock mean? PE P/E ratio reflects the relationship between the market price of the company's stock and the company's profitability (earnings per share), and investors pay more attention to the company's stock. PB P/B ratio reflects the relationship between the company's stock market price and the company's solvency (net assets per share), and the company's creditors are more concerned. EPS refers to earnings per share. Earnings per share, also known as after-tax earnings per dividend and earnings per share, is the basic index to analyze the value of each share. The traditional calculation formula of earnings per share index is: earnings per share = net profit at the end of the period ÷ total share capital at the end of the period. Earnings per share highlights the amount of profit allocated to each stock and is the basis for pricing according to the price-earnings ratio in the stock market. If a company's net profit is large, but its earnings per share are small, it means that its performance has been diluted too much and the price per share is usually not high. PE refers to the price-earnings ratio of stocks, also called "profit rate". The cost-benefit ratio is the ratio of the common stock price to the earnings per share of a certain stock. So it is also called stock price-earnings ratio or market price-earnings ratio. These can be understood gradually, and investors had better have some preliminary understanding of the stock market before entering the stock market. At the beginning, you can use A Niu Stock Treasure to simulate stock trading. There are some basic knowledge materials of stocks worth learning, and you can also establish your own mature knowledge and experience of stock trading through the above related knowledge. I hope I can help you, and I wish you a happy investment!

Excuse me, the earnings per share of the stock; What does PE mean? EPS means earnings per share. Earnings per share, also known as after-tax earnings per dividend and earnings per share, is the basic index to analyze the value of each share. The traditional calculation formula of earnings per share index is: earnings per share = net profit at the end of the period ÷ total share capital at the end of the period. Earnings per share highlights the amount of profit allocated to each stock and is the basis for pricing according to the price-earnings ratio in the stock market. If a company's net profit is large, but its earnings per share are small, it means that its performance has been diluted too much and the price per share is usually not high. PE refers to the price-earnings ratio of stocks, also called "profit rate". The cost-benefit ratio is the ratio of the common stock price to the earnings per share of a certain stock. So it is also called stock price-earnings ratio or market price-earnings ratio.

What do PB and PE in stocks mean? It is suggested that such questions can refer to Baidu Encyclopedia PB (average price-to-book ratio). Average price-to-book ratio = share price/book value. Among them, book value = total assets-intangible assets-liabilities-preferred stock equity. It can be seen that the so-called book value is the value of the company when it is dissolved and liquidated. If a company wants to liquidate, it must pay its debts first, and intangible assets will no longer exist. One of the key points of preferred stock is to divide the money first in liquidation, but there is no preferred stock in this stock market. In this way, if the book value is converted into net assets per share, PB is the price-to-book ratio that everyone understands, that is, PB (price-to-book ratio) = share price/net capital per share. Pe = price/profit share Pe refers to the price-earnings ratio of stocks, also known as "profit rate". The cost-benefit ratio is the ratio of the common stock price to the earnings per share of a certain stock. So it is also called stock price-earnings ratio or market price-earnings ratio (P/E ratio).

PE of stock. What does PB mean? A rookie "P/ERatio" means price-earnings ratio; Price-earnings ratio (PE or P/ERatio for short), also known as pricetoearnvinbo or market price-earnings ratio. "Priceshare" refers to the profit sharing of shares Priceshare, which represents profit sharing. That is, the ratio (P/E) between the stock price and the after-tax profit per share of the stock in the previous year is a dynamic indicator to measure the investment value of the stock. P/B ratio refers to the ratio of stock price to net assets per share. P/B ratio can be used for investment analysis. Generally speaking, the investment value of stocks with lower P/B ratio is higher, and conversely, the investment value is lower; But when judging the investment value, we should also consider the market environment at that time, the company's operating conditions, profitability and other factors. The calculation method of price-to-book ratio is: price-to-book ratio =(P/BV), that is, stock market price (P)/ net assets per share (book value).

What do you mean by an 8% stake? What do you mean by mortgaging stocks? Many stocks are locked up, but they are in urgent need of money and are reluctant to cut their meat. Because stocks are securities, 8% should be the annual interest rate of 8% if the stocks are mortgaged. Almost, the bank loan is only 5.35% a year.

What do you mean by sports? PE refers to the price-earnings ratio, that is, the ratio of stock price to stock earnings per share. However, there are many ways to choose stock price and earnings per share, so there are also many algorithms for P/E ratio. PEG is one of them, and his earnings per share is calculated based on the expected earnings per share of the year. For example, the current price of a stock is 10 yuan, and the earnings per share last year was 0.20 yuan. The expected earnings per share this year is 0.50 yuan, so his PE is 50 times and PEG is 20 times.

What does PE of a stock mean? The PE of a stock refers to the price-earnings ratio (PE or P/ERatio for short), and the price-earnings ratio refers to the ratio of the stock price to the earnings per share during an investigation period (usually 12 months). Investors usually use this ratio to estimate the investment value of a stock, or use this indicator to compare the stocks of different companies. "P/ERatio" refers to the price-earnings ratio; "Priceshare" refers to the profit sharing of shares Priceshare, which represents profit sharing. That is, the ratio (P/E) between the stock price and the after-tax profit per share of the stock in the previous year is a dynamic indicator to measure the investment value of the stock. Dividend rate: City companies usually distribute part of their profits to shareholders as dividends. Divide the dividend per share of the previous year by the current share price, which is the current dividend rate. If the stock price is 50 yuan, and the dividend per share is 5 yuan last year, the dividend yield is 10%, which is generally high, reflecting that the P/E ratio is low and the stock value is undervalued. Generally speaking, the P/E ratio is 0-13-that is, the value is undervalued14-20-that is, the normal level is 21-28-that is, the value is overvalued by 28-reflecting the speculative bubble in the stock market, and the dividend yield is zero. Because when the P/E ratio is greater than 100 times, it means that it will take investors more than 100 years to recover their capital, and the stock value is overvalued, so they don't pay dividends.

What does the id of the stock mean? The ID of the stock refers to the stock code. Coding rules of the two stock exchanges: According to the Securities Coding Implementation Plan of Shanghai Stock Exchange, the six-digit coding method is adopted, and the first three digits are different securities, as shown in the following table: 001××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××× 201××××× national debt repurchase; 310 ××××× treasury bond futures; 500 ××××××× 550 ××××××× Fund; 600×××A A shares; 700 ××××× rights issue; 710××××× share transfer; 701×××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××× 735 ××××× new fund subscription; 737 ××××× new share placement; 900×××B B shares.

What does the ADL of stock mean? It is a technical analysis tool to study the trend of stock index. Principle and calculation method of ADL index 1 ADL indicator principle ADL indicator is a technical indicator that takes the number of stocks that rise and fall every day as the calculation and observation object, so as to understand the rise and fall of stock market popularity, detect the strength of kinetic energy within the general trend, and then judge the future trend of the stock market. It is the accumulation of the balance obtained by subtracting the number of falling stocks from the number of rising stocks every day in all the stocks listed and traded in this market. That is, the difference between the number of stocks rising on the second day and the number of stocks rising on the first day is the ADL on the first day, and the number of stocks falling on the second day is also reduced by the number of stocks rising. Then add this difference to the ADL value on the first day to accumulate the ADL value on the second day, and so on. Therefore, we can know that ADL index is a simple addition and subtraction operation to calculate the cumulative result of the number of stock ups and downs every day, and compare it with the comprehensive index of stock market trend to predict the future stock market trend. Under normal circumstances, when the general trend index of the stock market rises, there will inevitably be more companies with rising stocks; On the contrary, the stock market trend index index fell, and the number of households whose stocks fell was more. The relationship between the two is often proportional, and the rise and fall of the stock market trend is the same as the strength of market sentiment. But when the stock market trend index is close to high or low, there are often exceptions. This is mainly because the calculation of the stock market trend index is generally based on the size of the stock market trend and the total share capital, which makes the rise and fall of high-priced stocks and stocks with large share capital circulation (that is, index stocks or constituent stocks) account for a very heavy proportion in the operation of the index and have a great influence on the rise and fall of the index. In order to attract the interest of buying, or induce sellers to sell, and achieve the purpose of effectively controlling the market, the main players in the market often use the characteristics of large stock capital or high stock market trend to deliberately raise or suppress the index stocks, thus indirectly affecting the rise and fall of the market trend. The ADL indicator is similar to the stock market trend index, which reflects the trend and trend of the general trend and does not provide a signal for the rise and fall of individual stocks. However, because the general trend index of the stock market is influenced by the index stocks under certain circumstances, the abnormal trend of these stocks (skyrocketing or plunging) will have an impact on the trend of the general trend index of the stock market, thus providing investors with untrue information. In order to make up for the possible distortion of the general trend index of the stock market, the volatility index is introduced into the analysis of the general trend index of the stock market to assist in judging the general trend index of the stock market. ADL indicator is a general trend indicator based on the number of stock ups and downs. Because its calculation method is to accumulate the difference between the number of rising stocks and the number of falling stocks in all transactions in the market, only the market index has the ADL index value, but individual stocks do not have this index. ADL index is simple in calculation and principle, which has a unique role in observing the actual popularity of the market. Second, the calculation method of ADL index The calculation of ADL index is relatively simple. Daily ADL is the accumulation of the difference between the total number of rising stocks and the total number of falling stocks every day. Generally, in order to accurately reflect the general trend, the cumulative value of ADL in a period of time is used as the ADL value of the day. The specific process is as follows: first, assume that the ADL value of the previous trading day is known, and then calculate the ADL value of the current day. If there are rising A shares, falling F shares and flat B shares on that day, the fluctuation standard here is the comparison between the closing price of that day and the closing price of the previous day. In this way, the calculation formula of the ADL value of the current day is: ADL of the current day = ADLA-F of the previous day, which is derived from the above formula: ADL of the current day = ∑A-∑F, where ∑ a represents the sum of the rising houses in each trading day since the first trading day, and ∑ f represents the sum of the falling houses in each trading day since the first trading day. What needs to be emphasized here is that, unlike other indicators, ADL indicators have neither weekly ADL indicators nor weekly ADL indicators in practice. Due to the increasing popularity of stock market technical analysis software, the calculation of daily ADL values will be completed quickly by computers. Investors do not need to calculate daily ADL values themselves, but mainly understand the calculation principles and methods of daily ADL indicators, so as to be familiar with various analysis methods and skills of ADL indicators. The general criteria for judging ADL indicators are different from other technical indicators. Generally speaking, ADL indicators can only be used for the analysis of market trends, not for individual stocks. Moreover, ADL indicators can only be used for the analysis of daily market trends. The application of ADL focuses on judging the trend of its curve, not the numerical value. The general criteria for judging ADL indicators mainly focus on the simultaneous trend and opposite trend of ADL curve and stock market trend index curve. Thirdly, the synchronous trend of ADL curve and stock market trend index curve is 1, and ADL curve and stock market trend index curve rise synchronously and hit a new high, so it can be judged that the upward trend of megatrends will continue, and it is unlikely that megatrends will reverse downward in the short term. 2. If the ADL curve falls synchronously with the stock market trend index curve and the innovation is low, it can be judged that the downward trend of the megatrend will continue, and it is unlikely that the megatrend will reverse upward in the short term. 3. In the long-term bull market, when the ADL curve shows a long-term upward trend, if there is a sudden sharp drop, then immediately turn around and hit a new high. At the same time, when the stock market trend index curve also shows a similar trend, it means that many forces are very strong, and the market may go up again and hit a new high. 4. In the long-term falling short market, when the ADL curve shows a long-term downward trend, if there is a sudden sharp rise in the meantime, then it immediately turns around and hits a new low, and the stock market trend index curve also shows a similar trend, which means that the short side is very strong, and the market may go down again and hit a new low. 4. The opposite trend of ADL curve and stock market trend index curve 1. In the long-term rising bull market, if the stock market trend index has entered a high level, the ADL curve does not rise synchronously, but begins to level off or fall, which is a signal that the upward trend of the megatrend may end. 2. In the long-term falling short market, if the stock market trend index has entered a low level, the ADL curve does not fall synchronously, but starts to level off or turn around and rise, which is a signal that the downward trend of the megatrend may come to an end. 3. The general trend index of the stock market fell from the high point, and rose again after finishing, approaching the previous high point or new high, but the ADL curve lingered or could not cross the previous high point, indicating that the general trend may reverse downward at any time. 4. The general trend index of the stock market rebounded from the low point, and then fell again, and approached the previous low point or hit a new low, but the ADL curve failed to fall below the previous low point and leveled off or turned around, indicating that the decline of the general trend may have turned around and may rebound upward at any time. The special analysis method of ADL index mainly focuses on the deviation of ADL curve and the relationship between ADL curve of that day and the average value of ADL of N days. V. ADL index deviation 1. In the bull market, the main force often controls the trend of some index stocks to maintain the upward trend of the market and achieve the purpose of attracting buying and pulling boats. When the main force of the market maintains the confidence of medium and long-term investors by controlling the sharp rise and slight rebound of index stocks, and the rest of the stocks rise in turn, the upward trend of the stock market will be very stable. When the bull market lasts for several months, the general trend index of the stock market is still rising slowly, and at this time, the DAL index hovers at a high level or even begins to turn around and decline, which shows that the upward trend of the general trend index of the stock market is mainly caused by index stocks, which is unmatched by other stocks, and the main players in the market show signs of pulling the boat. This trend is the top deviation of ADL index. When the ADL indicator deviates from the top, it usually means that the bull market in the stock market is coming to an end, and the general trend of the stock market is likely to reverse and fall soon. 2. Bottom Deviation In the short market, the main force often extends the downward trend of the market by controlling the trend of some index stocks, so as to induce sellers to sell and attract goods at a low level. At the beginning of the stock market decline, the popularity in the market was scattered, investors rushed to sell their stocks, and the stock market fell more and more slowly. When the short-selling market lasted for several months, with the gradual reduction of selling, the trading volume shrank extremely, and the market showed signs of reluctance to sell shares. Many stocks began to stop falling and stabilize, but at this time, the main players in the market did not collect enough cheap chips. In order to have enough space and time to attract blue-chip stocks on dips, the main players in the market will hit the confidence of medium and long-term investors by controlling the decline of index stocks again. When the general trend index of the stock market fell again and hit a new low, and the DAL index stabilized at a low level or even began to turn around, it showed that the downward trend of the general trend index of the stock market was mainly caused by the market's main force suppressing the index stocks in order to attract bargains. This trend is the bottom deviation of ADL index. When the ADL indicator deviates from the bottom, it usually means that the main force of the market has started to enter the market and the market is about to stop falling and rebound. Sixth, the shape of ADL curve is the same as other technical analysis indicators. The various forms of ADL curve are also an analytical method to judge the market trend and decide the trading opportunity. 1. When the ADL curve forms an M-shaped or triple-shaped top reversal at a high level, it may indicate that the general trend of the stock market will turn from strong to weak, and the general trend of the stock market is about to plummet, so the stock should be sold in time. If the curve of the general trend of the stock market also appears the same shape, it can be more confirmed, and its decline can be judged by M-head or triple top theory. 2. When the bottom of the ADL curve is reversed at a low level, such as the bottom of W or the bottom of triple bottom, it may indicate that the general trend of the stock market will turn from weak to strong, and the general trend of the stock market will rebound upward, and a small amount of stocks can be absorbed on dips. If the same pattern appears on the general trend curve of the stock market, it can be confirmed that the increase can be judged by W-bottom or triple bottom's pattern theory. 3. The shape accuracy of M head and triple top in 3.ADL curve is greater than that of W bottom and triple bottom. 7. The relationship between 7.ADL line and MA line 1. When the ADL curve and MA curve are arranged at the bottom for a long time, the ADL curve starts to move upwards, and the MA curve also flattens or rises slightly at the same time, indicating that the overall upward kinetic energy of the stock market trend begins to increase, and the long-term upward movement trend of the stock market trend is initially formed, and investors can start to absorb stocks on dips. 2. When the ADL curve begins to break through the MA curve, it shows that the upward momentum of the general trend of the stock market has been quite sufficient, and the long-term upward trend of the general trend of the stock market has been formed. If it is accompanied by a large volume of transactions, it will be more confirmed. Investors should resolutely buy strong leading stocks in Man Cang. 3. When the ADL curve breaks through the MA curve upwards and executes for a period of time, it starts to pull back downwards, approaching or touching the MA curve. As long as the ADL curve does not effectively fall below the MA curve, it indicates that the stock market trend is a strong consolidation. Once the ADL curve goes up again, it shows that the kinetic energy of the stock market trend will gather again, and the stock market trend will enter a strong pull-up stage. Investors can buy low-volume stocks or hold stocks to be increased in time. 4. When the ADL curve and MA curve extend upward again at the same time, it shows that the general trend of the stock market is still strong, and investors can hold strong stocks all the way, or buy stocks with lower trading volume at the beginning. 5. When the ADL curve and MA curve are executed upward for a long time, and the ADL curve is far away from the MA curve because of its faster execution speed, once the ADL curve turns down, it shows that the short-term kinetic energy consumption of the stock market trend is large, and the stock market trend needs a short-term correction, and investors should sell stocks with excessive gains in the short term. 6. When the ADL curve is executed from a high position, it shows that the upward kinetic energy of the stock market trend has been exhausted, while the downward kinetic energy has begun to accumulate. The mid-term upward trend of the stock market trend has ended and the mid-term downward trend has begun to take shape. Investors should sell stocks in time. 7. When the ADL curve runs down from the high position and breaks through the MA curve, the MA curve also begins to turn down, indicating that the strong upward trend of the stock market trend has ended, and the long-term downward trend of the stock market trend is becoming increasingly obvious. Investors should resolutely wait and see or sell the remaining stocks on rallies. 8. When the ADL curve goes down under the MA curve, it shows that the weakness of the stock market trend is extremely obvious, and the only investment decision investors can make is to hold the currency and wait and see. 9. When the ADL curve is executed under the MA curve for a long time, it begins to turn around slowly, indicating that the downward trend of the stock market trend has temporarily slowed down and the stock market trend is in a weak consolidation pattern. Investors should continue to observe and not take action easily. 10. When the ADL curve starts to break through the MA curve upward below the MA curve, it shows that the rebound kinetic energy of the stock market general trend begins to strengthen, and the stock market general trend will stop falling and rebound. At this point, investors can buy a small number of strong stocks and make a short-term rebound, but they can't continue to fight. Once the market falls again, they should leave the market in time to wait and see until the long-term decline of the stock market trend begins to take shape.

What does stock art mean? The landlord wants to ask if it is an ATR indicator. The technical index of (ATR) average volatility channel is an index showing the market change rate. How to use ATR analysis: ATR index does not indicate the price direction, but only the intensity of price change. Early ATR indicators were mostly used in the futures market, and now they are also used in financial markets such as stocks and foreign exchange. Reversion or beginning of price trend: extremely high ATR or extremely low ATR value can be regarded as the reversal of price trend or the beginning of the next trend. As a technical indicator based on price fluctuation similar to the Bollinger Band, the average value of the real fluctuation range can not directly predict the price trend and its stability, but only indicates the frequency of trading activities. Lower ATR (i.e. smaller actual volatility) indicates that the trading atmosphere in the market is relatively calm, while higher ATR (i.e. smaller actual volatility) indicates that the trading atmosphere is relatively strong. Long-term low ATR is likely to indicate that the market is accumulating strength and gradually starting the next price trend (which may be a continuation of the previous trend or a reversal of the trend); Very high ATR is usually caused by the sharp rise or fall of prices in a short period of time, and usually this value cannot be maintained at a high level for a long time. Stop-loss and profit-taking setting: Traders can also use ATR to set their own stop-loss and profit-taking prices. Because ATR calculates the real range of currency pair fluctuations in a certain period of time, it can be used as a standard for calculating stop loss and win. Briefly summarize, refer to the relevant aspects of this system in detail to learn, and practice with the simulation disk at the same time, you can quickly and effectively master the skills. Niu Gubao's current simulation of stock trading is not bad, and many functions are enough to analyze the market and individual stocks, which is very helpful to use. I hope it will help you, and I wish you a happy investment!

4. Interpretation of prepayment rate indicators?

The prepayment rate index aims to comprehensively reflect the prepayment level of basic assets in the market of individual housing mortgage asset-backed securities (RMBS) and cultivate the target index of interest rate swap of RMBS.

Monthly repayment amount and conditional prepayment amount are two basic indicators for calculating prepayment amount.

It is suggested that investors should not only pay attention to the product structure, repayment methods of assets and other factors when choosing RMBS, but also make a reasonable prediction of the prepayment of RMBS, fully consider the prepayment of similar products of the sponsoring institutions, and refer to the overall trend and fluctuation range of prepayment of similar products in the market.
