The cruel irony: the best days always come right after the worst ones. The exact moment panic sellers are most tempted to exit — after a crash — is when the recovery snapback happens. Miss the panic, miss the bounce.

Why does this happen?
🔄
Best days follow worst days
7 of the 10 biggest Nifty 50 single-day gains happened within 2 weeks of a major crash. When panic is at its peak and sellers are fleeing, the market sets up for a violent snapback. You have to already be in to catch it.
🧠
Timing is neurologically impossible
To avoid the worst days and catch the best, you'd need to make two perfect calls — when to sell and exactly when to buy back. Even professional fund managers consistently fail at this. Research shows ~90% of active timing attempts underperform buy-and-hold.
📉
Behaviour gap is larger than fee drag
DALBAR's annual investor behaviour study shows the average equity investor earns 3–4% less per year than the index — not because of fund fees, but purely because of bad timing decisions. Over 20 years, that gap is worth more than the original investment.
Model based on Nifty 50 data (NSE India, Jan 2000–Dec 2024). Each 'best day missed' reduces annualised return by ~0.35% based on observed market patterns. Actual impact varies by period and holding. Not investment advice.
