per chatgpt, 
Yes, it’s true. The phenomenon you’re referring to is often called the “few days effect” or “power law of returns.” In the case of the SPDR S&P 500 ETF Trust (SPY), a significant portion of its annual gains typically comes from just a few trading days each year12. Missing out on these key days can drastically reduce overall returns.
For example, if an investor were to miss the top 10 best-performing days in a year, their annual return could be significantly lower compared to staying invested throughout the entire year2. |
