What Happens If You Miss the 10 Worst Days of the Year?

What Happens If You Miss the 10 Worst Days of the Year?

| October 17, 2018

After more than three months without a single 1% change (up or down) for the S&P 500 Index, volatility came back—and in a big way—this past week. 

This brings up an interesting question: What would happen if you could avoid all the big down days for stocks while invested in a portfolio mimicking the makeup of the S&P 500? Of course, no one can really do this, but it’s still a very important exercise for investors to examine on the futility of market timing.

If you could have avoided the 10 worst days of each year for the S&P 500 since 1990, you would have had average annual gains of close to 40%. However, saying you’ll do that—and actually being able to accomplish it—are two totally different things.

What if you missed the 10 best days of the year? Well, in that case, you would have been down on average 12.8% a year since 1990. Per Ryan Detrick, Senior Market Strategist, “Let’s get one thing straight—no one can predict the 10 best or 10 worst days of the year. Although it would be fun to somehow do this, the exercise hammers home that for the average investor, being invested and not making a lot of short-term bets may be the best way to accumulate long-term wealth.”

What happens if you miss the ten best and worst days of the year

Here are some key takeaways from this exercise:

  • Even if you missed the 10 best days of each year, you still would have been in the green six times (1991, 1995, 1996, 1997, 2013, and 2017).
  • Market timing made the smallest difference in your portfolio last year. If you missed the 10 worst days of the year in 2017 your portfolio gained 31.1%, but if you missed the 10 best days of the year your portfolio still rose 8.6%.
  • The most volatile days mattered more in 2009. If you missed the 10 worst days in 2009, your portfolio added 88.8% for the year, the largest gain in any year of the exercise. If you missed the 10 best days of that year, your portfolio lost 18.7%.
