History

Historical Context

The dot-com bubble burst in 2001, following a period of rapid growth in technology stocks that began in the late 1990s. This event led to significant market volatility, with only 19% of S&P 500 constituents outperforming average returns. The rise of passive funds, now comprising 52% of U.S. stock and bond investments, reflects a shift towards risk management amid ongoing economic uncertainty.
