P/E
Price-to-Earnings
TL;DR
How much you pay for one rupee of yearly profit.
If a company earns ₹10 per share each year and the market price is ₹200, P/E is 20 — you are paying ₹20 today for every ₹1 of next year's profit. Lower is "cheaper", higher is "pricier", but pricey can be justified for very high-quality businesses.
