The S&P 500 index recently experienced a notable decline, closing lower after reaching a new all-time high (ATH) the previous Wednesday. This week marked the 178th occasion on which the S&P 500 lost more than 1.5% on a Friday, with historical data indicating that such losses are typically followed by an average additional loss of 0.3% on the following Monday. Over the past 26 trading days, the index has been expected to regain the 1.7% drop recorded on Friday, with a potential 4% gain over a three-month period. Notably, the index has gone 35 sessions without consecutive declines exceeding 1%, the longest such streak since late December, a phenomenon that occurred only three times in the past year. This trend will be tested as investors continue to buy the dip amid recent market fluctuations.
