What Nifty forward P/E is actually telling us — and what it isn't.

The Nifty forward P/E multiple, at time of writing, is approximately 22.4x. This is above the 10-year average of 20.1x and roughly one standard deviation above the long-term mean. The headline conclusion — that the index is expensive — is the sort of conclusion that generates page views and precisely no insight.

The forward P/E of any index is, on its own, one of the least useful valuation metrics available. It obscures composition, ignores balance sheet strength, and misses sector-specific dynamics that dominate the actual return experience.

What the composition is doing

The Nifty is not the Nifty of ten years ago. IT services now constitutes roughly 13% of the index versus 21% a decade ago. Private financials have grown to 32%. Consumer discretionary has expanded meaningfully. The sectoral weight shift alone has moved the "structural" forward P/E of the index by 2-3 turns.
