Clean Harbors (CLH) is up 8.1% today. Here is some analysis on what might have caused this price movement.

Analysis: The most likely driver is investor optimism around the company’s second-quarter 2026 earnings event on July 29, especially after management previously pointed to year-over-year adjusted EBITDA growth in the quarter and lifted parts of its 2026 outlook earlier this year. Additional support may have come from a fresh bullish Wall Street initiation and the company’s recent acquisition activity, which reinforces its expansion story in environmental and industrial services.
