"Equity works" is usually argued with survivorship stories. It should be argued with the index's own numbers — which are public, long, and currently inconvenient (the Nifty 50's one-year return is negative as of September 2026, which makes this the right moment to have the argument). The claim this page defends is modest: for money with a five-year-plus horizon, no emergency at its heels and no leverage against it, a boring index position has historically compounded well beyond Indian inflation — and the measurable cost of not staying in exceeds almost any timing edge an amateur can execute.
What does "works" mean? The index, not a stock pick.
NSE's own Nifty 50 factsheet (as of 30 September 2026) puts the index's total-return CAGR since inception (base date November 1995) at 12.12% — 10.61% on the price index, the gap being dividends. Set against a thirty-year run of Indian inflation that has mostly lived between 4% and 8%, the spread is the entire case: not a promise, a long historical average with volatility (about 22% standard deviation, same factsheet) as its toll. The one-year figure in the same factsheet is −7.1% — quoted deliberately, because anyone presenting equity's case without the drawdowns is selling something. Note also what "works" does not say: the index worked; your stock picks, your timing and your fund selection are separate claims, each with its own survivorship problem (our cost pages cover the fund-selection drag).
The measured cost of not being there
The most-cited US evidence (J.P. Morgan's Guide to Retirement chart, covering January 2005 to December 2024): $10,000 left fully invested in the S&P 500 grew to about $71,750; missing the ten best days cut it to about $32,871; missing the sixty best days left about $4,700. The same research notes the mechanism that makes this brutal: most of the best days cluster within two weeks of the worst ones — exactly the weeks when sitting out feels wisest. India-specific studies of the same design exist in smaller numbers, and the structural point travels: the days you most want to skip and the days that pay for everything are neighbours.
The missing-days arithmetic
J.P. Morgan's hypothetical $10,000 in the S&P 500, January 2005 to December 2024, as reported by CNBC. The clustering row is the mechanism: the best days hide inside the worst fortnights.
View the numbers as a table
| Strategy | End value | Annualised |
|---|---|---|
| Fully invested | $71,750 | 10.4% |
| Missing the 10 best days | $32,871 | 6.1% |
| Missing the 60 best days | $4,712 | −3.7% |
| The catch | 6-7 of the 10 best days fell within two weeks of the 10 worst | — |

The honest counterpoint
Independent analyses make a fair objection: missing the ten worst days beats buy-and-hold, and missing both the best and worst tens historically lands close to buy-and-hold. The objection is real — and its practical translation is not "timing works"; it is "you cannot reliably catch the good days without being present for the bad ones." Nobody has demonstrated a repeatable process for doing the first without the second, which is why the evidence still argues for presence rather than prediction. That is a statement about published process, not about cleverness.
The four cases where equity does not work
- Money with a deadline. Equity's 12% average is earned across decades, not quarters; a five-year window can genuinely end underwater — the index's worst five-year stretches have done exactly that. Inside five years, debt is the right answer (the goal-SIP calculator separates horizons).
- No emergency fund. The RBI's financial-education material puts the liquid buffer first — roughly six months of expenses — for a mechanical reason: without it, the first bad month forces selling equity into exactly the drawdown the long-run average assumed you'd wait through.
- Leverage. A 22%-volatility index falls 40-60% in bad episodes; borrowed money converts that from a paper drawdown into forced liquidation at the bottom. Margin is the one input that reliably converts a workable asset into a ruinous one.
- Unfinished behaviour. The average holding-period data is merciless: AMFI recorded 53.4 lakh SIP discontinuations in March 2026 alone, against record gross inflows the same season. The asset works; the sequence of quitting does not. The worst-SIP arithmetic shows what those discontinuations cost.
The boring conclusion
An index SIP in equity, an emergency fund outside it, a horizon of at least five years, no leverage, and instructions you follow when they feel wrong — that combination, not any stock, tip or fund, is what "equity works for almost everyone" means. The exceptions are the four conditions above; they are also the four things entirely under your control.
Educational content, not financial advice. Index figures from NSE Indices' official Nifty 50 factsheet as of 30 September 2026 (TRI 12.12% CAGR since inception, price 10.61%, 1-year −7.09%, σ 22.39%); the missing-days chart is J.P. Morgan's Guide to Retirement (Jan 2005-Dec 2024 window) as reported by CNBC in April 2025 — a US study on the S&P 500, cited for mechanism; SIP discontinuation and inflow data from AMFI's September 2026 release as reported in the press. Past averages bound nothing about future returns; the four failure conditions are the point of the page.
