Stocks have historically reacted well to Fed rate cuts. Since 1971, the first Fed cut has led to positive returns for investors 100% of the time in the next six months, with an average gain of 13%, according to Fundstrat's Tom Lee.

U.S. stocks rose after the Federal Reserve lowered its benchmark interest rates by 50 basis points to a range of 4.75% to 5%. That was the first rate cut in over four years that marked the beginning of a monetary-easing cycle in the world's largest economy.
