Recent Updates on CLH stock
Clean Harbors shares saw positive sentiment over the last day as multiple analysts raised price targets following solid Q4 results and largely in-line initial 2026 guidance.

Spark’s Take on CLH Stock
According to Spark, TipRanks’ AI Analyst, CLH is a Outperform.
The score is driven primarily by solid financial fundamentals (scale, stable gross margins, and a notably improved balance sheet as reported) and supportive technical momentum (above key moving averages, positive MACD). These positives are tempered by premium valuation (P/E ~38) and some recent cash-flow conversion/FCF volatility, while the earnings call adds a modest positive due to steady 2026 growth guidance and strong capital returns despite near-term segment and macro headwinds.
