8 September 1998: The Dow posts a record 380-point gain

The Dow surged about 380 points, then the largest point gain in its history, after Fed chair Alan Greenspan hinted days earlier that interest rate cuts were possible amid the global turmoil. Russia's default and fears about hedge funds had battered stocks for weeks. The rebound showed how quickly sentiment can swing when the central bank signals support. The Fed did cut rates three times that autumn.

The lesson: Central bank signals can rapidly shift market sentiment, for better or worse, in a single session.

What it meant for investors

$1,000 in S&P 500 index fund at the start of 2000 → $4,626 today, vs $4,626 in the S&P 500.

We start the clock at the start of 2000, the first year in our price data after the event. That is 4.6 times the money, but $0 less than a plain index fund made over the same years.

What S&P 500 index fund teaches: Owning the whole market removes the risk of picking the wrong company but not the risk of a lost decade, so time horizon matters as much as diversification.
