The average monthly price to earnings ratio of Shanghai A shares in 2010

As of today, the Shanghai P/E ratio is the average annual P/E ratio.

2007 average P/E ratio.

For the times, 2007 soared rapidly and reached its peak, during which the Shanghai Composite Index.

From 998 in June 2005 to 6,124 in October 2007, this is a six-fold increase in just over two years. Subsequently, near the end of the share reform, the stock index turned back in the feast of PetroChina (**, consultation) listing, A shares.

The biggest bull run ever is over.

The average P/E ratio refers to the ** market.

A representative stock price index.

The average P/E ratio.

The P/E ratio is the ratio of the current market** per share to the net profit per share, i.e., PE=P EPS. Where: PE - P/E ratio; p-Current market per share**; EPS - Net income per share.

Suppose there are only two **a, b, **a are ** shares in a market, with a share capital of 100 billion shares.

**b is a small-cap stock with a share capital of 10 million shares.

The P/E ratio of A is 20 times, and the P/E ratio of B is 10,000,000 times.

If it is weighted average by market capitalization.

A's market cap is 10,000 times that of B, so A's weight is 10,000 times that of B:

As a result, the price-earnings ratio of parent company C is 1,000.1 billion yuan, 50 billion and 10 yuan = times.

That is to say, whether a small-cap stock B is added to the calculation, whether its P/E ratio is tens of times or hundreds of millions of times, will not have a huge impact on the average P/E ratio of the entire market, so if you use the algorithm I said, whether to use dozens of ** blue chips or all use more than 1000** votes to calculate the average P/E ratio of the market, there will be no big difference.
