By analyzing the price-earnings ratio, investors can judge the value of the stock, as well as the market's expectations and risks of the stock.
3. Factors affecting A-share P/E ratio A-share P/E ratio is affected by many factors, including industry cycle, macroeconomic environment, corporate profitability and market sentiment.

The P/E ratio is only an indicator, and investors need to comprehensively consider other factors and make comprehensive analysis and judgment.
