During the dot-com bubble, investors who sold at the first sign of a wobble missed massive gains. Analysis shows that even after the crash, buy-and-hold investors were profitable, while those who sold early were not. The worst financial outcome is panic-selling at the bottom of a crash, which locks in losses.

Tech culture, especially during hype cycles, glorifies high-risk, all-in bets. However, the most critical factor is often simply surviving long enough for your market timing to be right. Not losing is a precursor to winning. Don't make existential bets when endurance is the real key to success.
This anecdote illustrates the peak irrationality of the dot-com bubble. A tech hedge fund manager, despite being up 135% year-to-date, found he was the worst performer at a dinner with peers. Recognizing this as a sign of a top, he went 100% cash and was the sole survivor among them.
Gaonkar identifies her biggest error with NVIDIA wasn't selling too early, but failing to re-evaluate and buy back in later. The psychological pain of "sunk cost bias" makes it incredibly difficult to re-enter a position at a higher price, even when the fundamental thesis has improved.
The dot-com era was not fueled by pure naivete. Many investors and professionals were fully aware that valuations were disconnected from reality. The prevailing strategy was to participate in the mania with the belief that they could sell to a "greater fool" before the inevitable bubble popped.

During the dot-com era, savvy investors recognized they were in a bubble but termed it an "iron bubble," believing it would persist.

The dot-com bubble didn't create wealth in 1999; it destroyed it. Generational wealth came from buying and holding survivors like Amazon *after* its stock had fallen 95%. The winning strategy isn't timing the crash, but surviving it and holding quality assets through the long recovery.
According to investor Howard Marks, people sell assets either because they're up (to lock in gains) or down (out of panic). Both are poor reasons. The only valid reasons to sell are if your original investment thesis is no longer true, or if you've found a demonstrably better opportunity.
