In 19 of the past 21 years, investors were whiplashed by market drops of over 7%, a number high enough to cause discomfort or even panic.

But as a recent Oppenheimer note points out, the market has only had a negative annual price return in just six of those years. In other words, the turbulence during the year usually doesn’t harm the bottom line.

It also means last year’s results — which saw an annual negative 7.03% price return for the S&P 500 index amid a drop of 19.78% at the market’s worst — is uncommon.

The reason why, according to Oppenheimer analysts, is because the markets have undergone “dramatic technological changes” and “have become much more prone to rotation, rebalancing, and profit-taking. Adding to these trends is globalization and more central bank transparency.

Investors get over good and bad news more quickly

Today, Investors have a ton more information at their fingertips and are making decisions much more quickly, and all these changes have made markets “quicker to discount both good and bad news and developments,” Oppenheimer’s note says. In other words, markets get over things quickly and move on.

Another note from Bank of America Merrill Lynch out Friday shows how this has changed over time: “Once upon a time (between 7th Sept 1929 & 22nd Sept 1954) it took 9,146 days for the S&P 500 to reach a new high following a >20% bear drop; this time S&P 500 took just 215 days to recover & surpass its old high.”

Though big picture economic cycles aren’t happening more frequently — on the contrary, the current expansion is exceptionally long — the pace for the market’s short-term ups and downs has quickened significantly.

The historic whiplash can be striking, especially around the financial crisis. The market was a disaster in 2008, with the S&P 500 index down 38.49%, the worst annual return in recent memory. But the following year it finished 23.45% higher — even when you factor in a horrible first quarter in which the market fell another 27.19%.

Market timing is even harder

Market timing is incredibly difficult already and ill-advised.

The stakes are high to get this right for those who do try. As the JPMorgan Annual Retirement guide says — many have noted this over the years — missing the best 10 days in the market absolutely kills portfolios over the long run. From 1999 to 2018, annualized return is 5.62%. If you missed out on the 10 best-performing days, your return would drop to 2.01%. Missed out on 20 of the best days in the market? Your return would sink to -0.33%.

It goes downhill from there; staying out of the best 60 days would give an annualized return of -7.41%.
