The S&P 500 index has experienced a remarkable recovery in April 2025. Initially down more than 13% at one point during the month, the index's losses have narrowed to approximately 1.54% as of late April. If the S&P 500 manages to close April in positive territory, it would mark the largest monthly reversal to end positively on record, surpassing the previous record set in March 2009 when the index rebounded from a 9.3% decline to finish the month up 8.5%. Additionally, if the index rises another 1.5% in the final three trading days of April, it would be the first time since 1950 that stocks have fully recovered from a monthly loss exceeding 10%. To achieve this milestone, the S&P 500 needs to close above 5,611.85, which would also make it the first month since 1952 (when the five-day trading week began) to finish with gains after an intra-month drop of more than 10%. This recovery is notable given the index was down over 11% earlier in the month, highlighting a significant intra-month comeback.
