The P/E ratio is used by long-term shareholders to assess the company's market performance against aggregate market data, historical earnings, and the industry at large. A lower P/E could indicate that shareholders do not expect the stock to perform better in the future or it could mean that the company is undervalued.

In conclusion, the price-to-earnings ratio is a useful metric for analyzing a company's market performance, but it has its limitations. While a lower P/E can indicate that a company is undervalued, it can also suggest that shareholders do not expect future growth.
