We’ve officially entered buyback blackout season.Roughly one-third of S&amp;P 500 companies are already restricted from repurchasing shares as of today. That figure will climb rapidly, peaking near 80–85% by mid-October.This matters because buybacks are one of the biggest sources of demand for equities. When the blackout window closes, that bid disappears, right as markets face earnings season, macro risks, and heightened volatility.In other words, the largest buyer of stocks is about to step aside when liquidity is needed most.Source: StockMarket.News
