Goldman Sachs analysts note that as the quiet period for share buybacks lifts during the US stock earnings season, corporate buyback windows will rapidly reopen. Currently, only 12% of S&P 500 companies have open buyback windows, but an additional 22% are expected to exit their quiet periods by the end of this week. So far in 2026, US corporate buyback authorizations have reached a record $1.305 trillion, significantly exceeding $1.151 trillion in 2025, signaling a concentrated release of pent-up corporate purchasing power.
