Ban Ban found that some friends would confuse PE and PB with PE and PB loci.

Let me tell you what a quantile is.

The conditions mentioned in the course are any index of CSI 300 or CSI 500, with pe score between 0-50% and pb score between 0-20%.

Then we can judge that the current market as a whole is not overvalued, indicating that we can invest in the market.

Quantile indicates the position of the current value in the past ten years.

Generally speaking, it is the level of ranking.

For example, there are 40 students in a class, and Xiaoming won the first place in this exam. In other words, his score is 100%, which is the highest. If he is the twentieth, the score is 50%, which belongs to the middle position. If he comes last, his score is 0%, which is the lowest position in this exam.

So when the quantile is 0, it means that this value is at the lowest position in ten years, but it does not mean that it will not decrease, because we may decrease according to history.

Investment is about timing, location, people and harmony? In other words, just choose the right time? Buy reasonable stocks and have a good attitude.

Today is the first step? Choose the right time to enter? Today's content is to prevent everyone from entering the market in a hot market.

800 enterprises corresponding to the CSI 300 and CSI 500 Index? Are large enterprises and small and medium-sized enterprises in A-share listed companies the vane of the whole stock market? Therefore, we use the PEPB quantiles of these two indexes to decide the timing of entering the market.

Why is it 0-50%? And 0-20%? Banban will tell you about it, too.

Why are these two interval values? Have a look first? This is an interval value obtained by long-term investment researcher Dayu according to the overall performance of CSI 300 and CSI 500 in several bull markets in history.

Of course, you can define it as 0-40% or 0- 10%? But what about this? It will narrow the scope of investment opportunities.

So it belongs to a vague correctness in this range.

The first step is to judge a reasonable time? Is it equivalent to fishing? The first step is to cast a wide net? If you want to catch big fish (white horse stocks), you need a large area.

So this step should catch as many big fish as possible, so this step should not be too harsh? Indicators should be relaxed? But there are shrimps in it, and later courses will teach you how to screen them.
