The Trap of Recency: Why the Last Two Weeks Feel Like the Whole Story

Scott Sullivan |

When markets get choppy, something strange happens in our heads. The most recent price move starts to feel like the whole picture: yesterday's drop, this morning's headline. We assume that whatever just happened is what happens next. Psychologists call this recency bias, and it may be the single most expensive habit an investor can have.

 

Here is how it works. A few red days in a row, and a calm long-term investor suddenly feels certain the market is heading down for good. A few green days, and the same person is sure it is time to pile in. In both cases, the decision is being driven by the last thing that happened, not by a plan.

 

The trouble is that markets do not move in straight lines, and the recent past is a poor guide to the near future. DALBAR, which has studied investor behavior for three decades, has long found that the average fund investor tends to earn less than the funds they own. Why? Largely because they buy and sell at the wrong moments, chasing what just went up and fleeing what just went down.

 

Consider a simple example. Say the market falls 8% over two weeks. Recency bias whispers that the next move is surely more of the same, so you sell. But history shows that some of the market's best days tend to cluster close to its worst ones. Miss a handful of those rebound days by sitting in cash, and your long-term return can shrink dramatically. All because a two-week stretch felt like a permanent trend.

 

None of this means volatility is comfortable. It isn't. But the goal isn't to feel comfortable in the moment. The goal is to keep your behavior steady when your instincts are shouting.

 

A few habits help. Check your accounts less often, since daily watching only magnifies recent noise. Write down why you own what you own, so a rough week doesn't quietly rewrite your reasoning. And remember that a downturn only becomes a permanent loss when you make it one by selling.

 

As we often say, disciplined investing is supposed to be boring. The investors who do best are rarely the ones with the sharpest reflexes. They are the ones who refuse to let the last two weeks tell them the whole story.

 

Your trusted advisor has built a plan designed for your full time horizon, not for the mood of any single week. When markets turn noisy, that plan is exactly what keeps recent events in their proper place.
