Back in the spring, the stock market appeared to be in free-fall. From the April 2 “Liberation Day\u201d tariff announcements to April 8, the S&P 500\u00ae dropped by about 12%<\/a>. Then, on April 9, the S&P 500\u00ae had its best single-day gain in about 17 years<\/a>. And by early summer, as the likely magnitude of the tariffs became somewhat clearer, the market came roaring back and recorded a new high by the end of June.\u00a0<\/p>\n\n\n\n

This episode of enormous short-term volatility illustrates how hard it is to get market timing right. To successfully time the market, you have to make two correct decisions: when to sell and<\/em> when to buy again. It is impossible for anyone to do that consistently over the long term. In fact, by trying to do so, investors generally lower their investment returns\u2014in part because markets can be unnervingly volatile both through the worst declines and <\/em>the subsequent recoveries. As a result, it\u2019s all too easy to miss the rebound and give up a significant portion of your return.\u00a0<\/strong><\/p>\n\n\n\n

In this post, we\u2019ll look at the historical evidence to show why market timing is such a costly strategy.\u00a0<\/p>\n\n\n\n

What happens when you sell during a market decline and wait for the market to recover?<\/h2>\n\n\n\n

During market volatility like what we witnessed earlier this year, it can be very tempting for investors to sell when markets are falling and wait for the recovery to invest again. We\u2019ll start by showing why that approach doesn\u2019t work.\u00a0<\/p>\n\n\n\n

For our analysis, we\u2019ll use US stock market returns from Kenneth French\u2019s data library over the 50-year period from June 1, 1976, to May 31, 2025. We\u2019ll assume you received a salary at the end of each month, $100 of which you invested in the broad US stock market, and that any uninvested cash earns the risk-free rate (also sourced from Kenneth French\u2019s data library). To keep things simple, we\u2019ll ignore the impact of taxes.<\/p>\n\n\n\n

The chart below shows what would have happened if you sold your investments each time the market fell 10%, 20%, 30%, 40%, or 50% below its previous one-year peak and invested everything again when the market fully recovered to that peak.\u00a0<\/p>\n\n\n\n

Even without seeing the data in the table, you might have been able to guess that you\u2019d get bad results from selling in a decline and then getting back in when the market\u2019s back at its peak. Investors want to \u201cbuy low\u201d and \u201csell high\u201d\u2014and this approach is the opposite.<\/strong> But what might be surprising is just how bad<\/em> the results are.<\/p>\n\n\n\n

Because the general long-term trajectory of the market is upwards, being out of the market can have a significant cost\u2014in the example above, that cost can literally be millions of dollars.<\/p>\n\n\n\n

A less extreme example<\/h2>\n\n\n\n

The example above is fairly extreme, and so is the outcome. What if you took a more measured approach to timing the market and got back in when the market recovered halfway from its most recent trough? This approach allows for the possibility of success, because you could end up buying investments at a lower price than what you sold them for (selling high and then buying low). For instance, the chart below shows what this strategy would have looked like during the period from 2007-2010, if you sold when the market declined by 20%. In that case, you would get to sell your investments at a higher price than what you\u2019d pay to buy them back. (Keep in mind that this wouldn\u2019t always be the case, though\u2014it just depends on how deep the decline ends up being.)<\/p>\n\n\n\n

\"\"\/
Sources: Kenneth French Data Library<\/a>, Wealthfront<\/figcaption><\/figure>\n\n\n\n

In practice, even this less extreme approach doesn\u2019t work over time. You don\u2019t get to \u201csell high\u201d and \u201cbuy low\u201d enough of the time to make up for your time out of the market. Let\u2019s look at this approach over the same period we covered above from 1976 to 2025. The chart below shows how this strategy would play out if you sold each time there was a 10%, 20%, 30%, 40%, or 50% decline relative to the recent one-year peak from June 1, 1976, to May 31, 2025 (again, assuming you have $100 to invest at the end of each month and ignoring the impact of taxes). And in this less extreme example, you\u2019d reinvest when the market recovered halfway from its most recent trough. Even when we look at this less extreme approach, you still get a far superior result just by staying in the market.<\/strong><\/p>\n\n\n\n

It\u2019s very hard to time the market<\/h2>\n\n\n\n

As further evidence that timing the market is hard, consider how often the best days (those with the highest single-day returns) occur shortly after deep declines.\u00a0<\/p>\n\n\n\n

The table below shows the 10 best single-day returns for the total US stock market (again using data from Kenneth French\u2019s data library) over the same time period. As you can see, every single one occurred following significant market declines. And in every case,\u00a0three weeks or less had passed since the last \u201cbad\u201d day (defined as one of the worst 50 days\u2014approximately 0.39%\u2014in the period).<\/strong><\/p>\n\n\n\n

Short-term market volatility such as that depicted in the table above is why you can expect to earn money from investing over the long term. Your ability to tolerate volatility is why you have the opportunity to earn more. Put more simply: no pain, no gain. Taking on some risk offers you the possibility of earning more than the risk-free rate.\u00a0<\/p>\n\n\n\n

Your best bet is to buy and hold<\/h2>\n\n\n\n

Most investors probably don\u2019t have rules like the ones we used in the examples in this post\u2014instead, their decisions are likely emotional. But no matter what\u2019s driving the behavior (selling in a decline and buying when the market appears to stabilize), the results are the same: you\u2019re not likely to come out ahead when you try to time the market. The annual DALBAR Quantitative Analysis of Investor Behavior report shows this pattern year after year: investors\u2019 behavior tends to lead to underperformance. In 2024 alone, DALBAR found<\/a> that average investors in equities underperformed the S&P 500\u00ae by more than 8%.<\/p>\n\n\n\n

This highlights the importance of having a portfolio that matches not only your investing time horizon and goals, but also your personal tolerance for risk.<\/strong> Even for two people with the exact same financial situation, the same portfolio might not be appropriate for both\u2014one might be more risk averse and have more trouble staying invested. Ideally, you want a portfolio that can help you reach your financial goals and<\/em> one that allows you to sleep at night.\u00a0<\/p>\n\n\n\n
