The Best Days During Bad Times
Market history reveals that the most significant single-day rallies often occur precisely when the market is gripped by extreme fear and experiencing a downturn. For instance, during the Global Financial Crisis of 2008—when the market plummeted by nearly 60 per cent—22 of the top 30 best trading days occurred during that very period.
Similarly, in 2006, when the market declined by 30 per cent due to heavy sell-offs by FIIs and DIIs, three of the top 30 best days took place during that time.
During the COVID-19 era, when the market fell by approximately 40 per cent, four of the top 30 best trading days were observed.
May 18, 2009: 17.7 per cent
April 7, 2020: 8.8 per cent
January 25, 2008: 7.0 per cent
October 31, 2008: 7.0 per cent
October 13, 2008: 6.4 per cent
October 28, 2008: 6.4 per cent
June 15, 2006: 6.3 per cent
The report clearly demonstrates the critical importance of maintaining investments, even during challenging times. If investors miss out on just a few of the market’s best-performing days, their long-term returns could be significantly diminished. Between January 2005 and February 2026, the top 5 days alone generated returns of approximately 56.2 per cent; the top 10 days, 111.5 per cent; the top 15 days, 178.6 per cent; and the top 20 days, nearly 261.4 per cent. This is because these strong-performing days often occur right amidst market crashes.
