You can ignore AI giants like SpaceX, but your 401(k) won't

SpaceX's stock surged 19.2% in its Wall Street debut, valuing the company at $2.1 trillion, potentially leading to its inclusion in major stock indexes. This impacts 401(k) investors as index funds, which now hold more U.S. investments than actively managed funds, track these indexes, with 21% of actively managed funds surviving and outperforming benchmarks over the last decade.
