Frequently Asked Questions

The PE ratio (Price-to-Earnings ratio) of Nifty 100 measures how much investors are paying per unit of index earnings. It is calculated by dividing the index price by the aggregate earnings per share of all constituents. A higher PE means investors are paying more for each rupee of earnings.
A good PE ratio depends on historical context rather than an absolute number. Nifty 100's 10-year average PE is approximately 22.01. A PE below this average may suggest relatively better value, while a PE significantly above it may indicate stretched valuations.
A lower PE can indicate better value, but it should not be read in isolation. A low PE may also reflect declining earnings expectations or structural challenges in the index constituents. Always read PE alongside PB ratio, dividend yield, and earnings growth trends for a complete picture.
The PE ratio on Index Screener is updated daily based on the latest available market data from NSE. The data is refreshed after market close on each trading day.
