The U.S. stock market's corporate buyback window is rapidly reopening as the earnings season blackout period ends. According to data from Goldman Sachs, only 12% of S&P 500 constituents are open for buybacks this week, with another 22% set to exit the blackout. Since October, buyback activity has been about 40% lower than this year's daily average. So far in 2026, buyback authorizations have reached a record $1.305 trillion, and actual buybacks in the first half of the year have increased by 15% compared to the same period last year. With limited supply of new stocks, the supply-demand balance is noticeably shifting in favor of buyback purchases, providing strong technical support for the U.S. stock market.
