Tom Lee says timing the market is the biggest mistake

Tom Lee says the biggest mistake investors make is trying to time the market.
His point is that a small number of best days often drive most of the long-term returns.
In Bitcoin, missing the 10 best days each year would reportedly turn the return deeply negative.
In stocks, the same idea shows up across history.
The S&P 500 has compounded strongly over the long run, but missing the best days can crush the entire outcome.
That is why sitting in cash can feel safe in the moment while quietly becoming the most expensive decision.
For $SPY investors, the hard part is not predicting every correction.
It is staying invested long enough to capture the days that matter.
