Missing Nifty's 5 Best Days Over 21 Years Slashes CAGR from 13.67% to 11.31%, Abakkus Mutual Fund Analysis Shows
Key Takeaways
- β’The Nifty 50 Total Return Index delivered a 13.67% compound annual growth rate over the 21-year period from 2005 to 2026 for investors who stayed fully invested.
- β’Investors who missed only the five best trading days during that span saw their CAGR fall to 11.31%, while missing the best 50 days reduced returns to approximately 1%.
- β’The market's strongest sessions often occur in close proximity to its weakest days, typically during heightened volatility, making it difficult to predict optimal re-entry points.
- β’The concentration of long-term gains in a small number of trading sessions is a structural feature of global equity markets, also observed in indices such as the S&P 500.
- β’The findings support the use of systematic investment plans, which enforce regular market participation and reduce the risk of being absent during critical rallies.

A 21-year analysis conducted by Abakkus Mutual Fund, covering the period from 2005 to 2026, demonstrates the significant impact that missing the stock market's strongest trading days can have on long-term investment returns.
According to the study, the Nifty 50 Total Return Index (TRI) delivered a compound annual growth rate (CAGR) of 13.67% over the full 21-year period for investors who remained fully invested throughout. However, for investors who missed just the five best trading days during that span, the CAGR declined to 11.31%.
The penalty for market timing becomes even more pronounced when more of the strongest sessions are excluded. Investors who missed the best 50 days saw their CAGR plummet to approximately 1%, a dramatic reduction from the 13.67% achieved by staying fully invested. Because compounding is exponential, even a 2.36 percentage-point annual gap translates into a substantial difference in terminal wealth over a two-decade horizon.
The findings underscore a well-documented principle in equity investing: because a disproportionate share of long-term gains is concentrated in a small number of trading sessions, attempts to time entry and exit points carry a substantial opportunity cost. The best days in the market frequently occur in close proximity to the worst days, often during periods of heightened volatility, making it difficult for investors to reliably predict when to re-enter after selling. This same pattern has been observed in studies of major global indices such as the S&P 500, reinforcing that the concentration of returns in a handful of sessions is a structural feature of equity markets rather than an India-specific anomaly.
For Indian retail investors, such data underpins the rationale widely promoted by the Association of Mutual Funds in India (AMFI) and asset managers for systematic investment plans (SIPs), which enforce regular participation regardless of market conditions and reduce the risk of being absent during the market's strongest moves.
The Nifty 50 TRI is a widely followed benchmark that measures the performance of the 50 largest companies listed on the National Stock Exchange of India (NSE), with dividends reinvested. It is commonly used as a gauge for Indian large-cap equity performance.
