What Is the Shiller CAPE Ratio?
The P/E, or price-to-earnings ratio, is a key number many investors look at when deciding to buy or sell a stock. It compares a company’s stock price to its earnings per share. In simple terms, it shows the price investors are willing to pay for each dollar of profit.
The CAPE ratio, or Shiller PE Ratio, is different from the traditional P/E. It accounts for inflation over the past 10 years.
