Wall Street romped to records Thursday as a delayed jubilation swept markets worldwide following the Federal Reserve’s big cut to interest rates. The S&P 500 jumped 1.7% for one of its best days of the year and topped its last all-time high set in July.

It's been quite the year for artificial intelligence (AI) chipmaker Nvidia ( NVDA 4.57%), which has seen its stock rise more than 161% year to date. Over the last five years, Nvidia's stock is up by more than an astounding 2,560%.

Just as Wall Street traders come to grips with the Federal Reserve’s interest-rate cut, Friday’s US options expiration threatens to whipsaw the market some more.
