The S&P 500 hit its dot-com crash low around 800 points in March 2003, down 49% from its 2000 peak. A $1,000 investment at that low grew to approximately $10,000-$11,500 by early 2024, a nearly 1,000% return over 21 years, driven by the 2003-2007 bull market, recovery after the 2008 crisis, and the long 2010s expansion.
