Two readers commented about avoiding the worst days on my post about the meaningless stats on missing the best days. The stock market had some bad days since then. I think some might be interested in reading about avoiding the worst days.
First I want to emphasize that the whole point of my previous post was that it’s IMPOSSIBLE to miss the best 10 days in 10 years. The odds are 1 in 2.8 billion billion billion, which is like winning the Powerball jackpot with a single ticket purchase back to back to back. By the same calculation it’s equally IMPOSSIBLE to avoid the worst 10 days. But since they asked, I compiled some numbers for avoiding the worst 10 days in 10 years. So here you go, more meaningless stats.
The rewards for avoiding the worst days are equally as impressive as the penalty for missing the best days. Look at this chart:
The exercise did produce some useful insights. Between July 1, 1997 and June 30, 2006, which is the timeframe Schwab used in its article, the best 10 days and the worst 10 days for S&P 500 were:
|Best 10 Days||Worst 10 Days|
All together the best 10 days were up 60%, and the worst 10 days were down 39%. You see the best days don’t necessarily fall in bull markets and the worst days don’t necessarily fall in bear markets. 7 out the 10 best days happened in the bear market from 2000 and 2002, during which the S&P 500 index lost 38%. 4 out of 10 worst days happened in 1997 and 1998, when the S&P 500 gained 71%.
The bottom line is that the stock market is volatile. Sometimes it goes up and down a lot. A good day on the stock market doesn’t necessarily mean good times are ahead. A bad day doesn’t necessarily mean good times are over. Ignore the noise.
