Open the brokerage app. Review the balance. Note that it is lower than last month. Open a news tab. Read three headlines. Return to the app. Tap "sell." Transfer the cash to a savings account paying 4.1%. Feel, briefly, like someone who has done something. Jonah Ferris did this four times between 2018 and 2023, each exit timed to a moment of maximum discomfort, each re-entry delayed by several months. His spreadsheet of trades looks decisive. His returns look like someone who was never quite in the market.
Compounding is not a reward for being right. It is a reward for staying. The mathematics are merciless on this point: the curve's steepest section is always toward the end, which means leaving early costs you disproportionately more than the exit price suggests. Volatility doesn't destroy compounding. Exits do. And exits almost never happen because someone evaluated the fundamentals calmly at a kitchen table at noon. They happen in the gut, at night, after the fourth bad week in a row.
Compounding is not a reward for being right. It is a reward for staying.
”J.P. Morgan's asset management research, published and updated across multiple annual guides, has tracked what happens when investors miss the single best trading days in a given period. Miss the ten best days in a twenty-year window and your annualised return roughly halves. The brutal footnote: those best days cluster directly after the worst ones. The investor who exits during a crash doesn't just absorb the drop. They sit in cash through the bounce, the thing that was supposed to justify all the anxiety.
So here is the suspended moment — not a metaphor, an actual one. The account is down eighteen percent. There is a cursor blinking. One option feels like control: sell, preserve what's left, wait for clarity. The other option feels like passivity, which your nervous system has been trained since childhood to distrust. But consider what the data says about the second option. Staying is not the absence of a decision. It is the decision that compounds. Jonah Ferris eventually stopped selling. His account recovered. That is less the point than this: the moment of maximum discomfort and the moment of maximum opportunity are usually the same moment.
Look back at your own exits — not to judge them, but to notice what triggered them. What you find there is more useful than any asset allocation.
