Clean Harbors (CLH) Stock Soars 5.9% on Earnings Beat

Clean Harbors (CLH) shares rose 0.24% today, marking the third consecutive day of gains, with a total increase of 2.25% over the past three days. The stock price reached its highest level since February 2025, with an intraday gain of 0.72%.

The strategy of buying CLH shares after they reached a recent high and holding for 1 week yielded moderate returns over the past 5 years, with an average annual return of 8.5%. While this is a modest return, it demonstrates the effectiveness of a buy-and-hold strategy with a focus on recent highs as a entry point. The consistency of returns, combined with the relatively low volatility of CLH, makes this strategy suitable for investors seeking steady growth. However, the lack of high returns highlights the importance of patience and a long-term investment horizon in achieving significant gains.

Clean Harbors' stock price experienced a significant boost in 2025, driven by several key factors. In the first quarter of 2025, the company reported earnings that exceeded market expectations, leading to a 5.9% increase in its stock price. This growth was primarily attributed to successful pricing strategies implemented across various segments of the business. The improved financial performance has bolstered investor confidence in the company's ability to deliver strong results.

In addition to the positive earnings report, Clean Harbors received a rating upgrade from Wall Street Zen, which changed its recommendation from "hold" to "buy" on May 1st, 2025. This upgrade likely contributed to the positive sentiment surrounding the stock, as investors responded favorably to the improved outlook. The upgrade reflects the company's strong fundamentals and its potential for future growth, further enhancing its appeal to investors.
