### What is PE Ratio?

PE Ratio is a financial metric that explains “what an investor is ready to pay to buy a share of a company based on the company’s earnings.”

For example, if the PE ratio is 20, the investor is ready to pay 20 times the company’s EPS (per-share earning) to buy a stock.

**Reference:** Oil company Chevron** **has a 5-year continued profit of $10, $20, $35, $50, and $80. Let’s assume that the company’s current stock price is $1200 because the most recent earnings are $80; for that reason, Chevron’s PE Ratio is $1200/$80 = 15. In other words, an investor who wants to invest in a Chevron company will get its money back over 15 years, according to the current earnings.

## How to Analyze PE Ratio?

As long-term investors, we always look for fundamental data and growth possibilities. The P/E Ratio helps us to understand the overall valuation of the S&P 500 Index.

By comparing S&P 500 PE ratio with historical data, we can analyze how the US Market is priced compared to history. It also helps us identify the right time to buy stocks to make good returns.

**Levels of P/E Ratio –**

The S&P 500 Average PE Ratio is 14-17, which means if the current P/E Ratio is near the historical average, then it may be a good time to invest because the market is reasonably priced based on history. On the other hand, if the P/E Ratio is higher than the average, the market may be overpriced or expensive, and prices may fall.

**But** that’s not the point where you can trade based on PE. It depends on market sentiment, your analysis, and fundamental considerations. For example, in the same chart, you can see market prices are reaching their high during the market down phase, and if you are short on that level only based on an expensive market (high price-earnings Ratio), you would have lost money.
