Clean Harbors (CLH): Evaluating Valuation After Recent Share Price Rebound and Evolving Industry Opportunities

Clean Harbors (CLH) shares have shown some movement over the past month, gaining roughly 4%. Investors might be weighing recent financial results as well as the company’s long-term potential in the environmental services sector.

See our latest analysis for Clean Harbors.

Clean Harbors’ share price has been relatively steady this year, recently climbing back above $227 after a strong week and building on optimism around ongoing growth in its environmental services business. However, with a one-year total shareholder return of -12.5%, momentum has cooled in the short term. Its three- and five-year total returns remain highly impressive.

If rising demand for sustainability solutions has you thinking more broadly, now’s a great moment to broaden your search and discover fast growing stocks with high insider ownership

With steady long-term returns and recent gains in revenue and profitability, investors now face a crucial question: does Clean Harbors still offer untapped value, or are markets already factoring in its future growth?
