Republic Services is trading lower in extended hours following a regular session that saw the stock face pressure as investors rotated away from defensive industrials. This shift in sentiment reversed a recent flight to safety that had previously favored stocks with steady cash flows, causing the company to underperform its peers like Waste Management and Clean Harbors, which both posted modest gains during the regular session. The move follows a broader market decline on October 7, where the Dow Jones Industrial Average shed 0.66 percent and the S&P 500 fell 0.22 percent amid ongoing concerns regarding artificial intelligence spending and sector-wide volatility.
