"I just moved everything to cash," said Renata Osei, setting her phone face-down on the table at her sister's kitchen. It was late autumn, two days after a bad week in the markets. She said it the way people announce they've finally seen a doctor — relief edged with defiance. Her sister nodded. Neither of them said anything else about it for the rest of the meal.
Here is the mechanism, and it is not complicated: compounding requires time in the market, uninterrupted. It is a process that builds on its own prior output, which means any gap resets the base. Compounding does not reward the person who chose best — it rewards the person who left last. The enemy was never the wrong stock, the wrong fund, the wrong moment of entry. It was the exit. One well-timed panic, sustained for eighteen months, can erase an advantage that took a decade to build.

In 2022, Fidelity reviewed its own account data and found that its best-performing investors had one thing in common: they had forgotten the accounts existed. Not a strategy. Inattention. The people who checked in and adjusted. Who responded to every signal. Consistently underperformed the ones who simply did not move. The finding was inconvenient enough that it circulated mostly as a joke. It shouldn't have.
The hour before you move your money is the most expensive hour in personal finance, and it never announces itself as such. It arrives dressed as clarity. You've looked at the numbers, you've read something alarming, and the decision to step out feels like the only rational one available. What you are actually doing is converting a paper loss into a locked one, and trading your position in a compounding chain for a seat on the sidelines with no guaranteed re-entry point. Renata's money sat in cash for fourteen months. She got back in higher than she left. The loss was quiet and it was real.
Most of what gets called investment strategy is just interruption management. Stay in long enough and the question of which fund you picked begins to matter less than the fact that you never left it.
