Larger-than-usual post-earnings stock swings by AI and hyperscaler companies have disrupted a historical pattern where smaller companies' results typically drive the most significant market movements, according to data from options analytics service ORATS. Traditionally, the early weeks of earnings seasons are dominated by major market leaders, with smaller companies taking center stage later on. However, this quarter has seen tech giants like Amazon, Microsoft, Google, and Meta produce substantial stock reactions, surpassing their average historical moves. Investors are closely scrutinizing whether AI capital expenditures are proving fruitful, leading to aggressive buying or selling of shares. Data from ORATS indicated that options straddles, a strategy combining put and call options, fetched the largest average gains in the first week of the second-quarter earnings season, averaging 23%. This contrasts with the historical average of a 2% loss for the same period over the last 12 quarters. In later weeks, the strategy saw average losses, with week four producing a 6% loss compared to a historical average of 5%.
