The PE Buy/Sell Zone on a stock overview page shows whether a stock is trading in the Buy or Sell Zone based on its historical price-to-earnings ratio (PE ratio). The PE ratio compares a company's stock price to its earnings per share, determining whether it is overvalued or undervalued. This section also displays the percentage of time the stock has traded below its current PE level.

For example, Infosys is in the Sell Zone in the screenshot below as its P/E when checked, was historically lower than the current P/E value.

To get a detailed analysis, click the arrow in the top-right corner of the feature. This will redirect you to a page where you can check whether the stock typically trades above or below its current PE level on a standalone or consolidated basis, during specific time frames.
