One day after we presented data for the S&P 500 having the worst April performance since 1932 (see article), the markets showed incredible rally today on the news that there would be a 90-day pause on tariffs to allow for negotiations between U.S. and trading partners. The announcement of the pause had an immediate and eye-popping impact on the U.S. markets. The S&P 500 gained 9.52%, Dow Jones Industrial Average added 7.87%, Nasdaq Composite index increased by 12.16%, and Russell 2000 grew by 8.66%. These large single-day gains cemented their place in market history. The S&P 500 gain is the tenth largest since 1930, Dow Jones Industrial Average gain is the fifth largest since 1992, Nasdaq Composite gain is the second largest since 1971, and Russell 2000 gain is the third largest since 1987. We have prepared four charts to show the largest single-day gains for the four major U.S. market indices.
