Research brief
Clean Harbors closed at $312.9, up 3.0% for the week and 7.4% over four weeks, with volume rising to 3.8M shares, or 1.4x its 13-week average. The stock remains 8.5% above its weekly Trend Line and 37.5% above Sharemaestro Fair Value, but activity pressure is still negative, leaving the setup constructive rather than cleanly confirmed.
- Clean Harbors finished the week at $312.9, up 3.0%, with 4-week, 12-week and 52-week returns of 7.4%, 7.5% and 33.6%.
- The weekly Trend Signal remains active for a 30th week, with price 8.5% above the $288.3 Trend Line and 6.9% below the $335.9 52-week high.
- Volume reached 3.8M shares, equal to 1.4x the 13-week average and 1.6x the 52-week average, giving the latest advance better participation than most recent weeks.
- The US Waste Management group is weak on signal breadth, with only 11.8% active trend breadth and 11.8% positive Relative Strength breadth, making CLH an industry outlier.
- Risk evidence is mixed: activity pressure remains negative at -0.15, the stock trades 37.5% above Fair Value, and recent weekly volatility is running at 3.6%.
Price action stays high in the range
Clean Harbors ended the week of 31 July at $312.9, adding 3.0% after a 2.2% decline in the prior week. The move leaves the shares in the upper part of their 52-week range at 82.9%, still 6.9% below the $335.9 high and well above the $201.3 low. Momentum remains broadly positive, with gains of 7.4% over four weeks, 7.5% over 12 weeks, 20.4% over 26 weeks and 33.6% across the full year.
The weekly Trend Line sits at $288.3, placing the close 8.5% above the key regime level. Sharemaestro Fair Value is $227.6, which puts the stock at a 37.5% premium. That premium reflects persistent demand, but it also raises the bar for further confirmation because the shares are no longer trading near a value anchor.
Industrials were soft, Waste Management breadth was thinner
The sector backdrop was not especially supportive. US Industrials averaged a 1.7% weekly decline and a 3.6% four-week loss, with trend breadth at 52.0%, Market Dynamics breadth at 54.0% and Relative Strength breadth at 53.0%. Against that sector tape, Clean Harbors ranked in the 77.6th percentile across 640 US Industrials on Sharemaestro’s peer-relative view.
The industry context is more striking. US Waste Management stocks averaged a 0.3% weekly decline, a 5.7% four-week fall and a 2.6% 12-week loss. Only 11.8% of the group had active weekly trend signals and only 11.8% showed positive Relative Strength breadth, though Market Dynamics breadth was healthier at 58.8%. CLH ranked sixth of 17 industry peers for the week, third over four weeks and eighth over 12 weeks, placing it in the 87.5th percentile within the group.
Trend Signal is intact, but pressure has not fully confirmed
The setup remains a continuation case rather than a fresh breakout signal. Clean Harbors has an active Trend Signal and a 30-week active streak, with 42 active weeks over the past year, or 80.8% trend breadth. Relative Leadership is positive at 8.82 and has improved sharply over the past month, which supports the view that CLH is separating from weaker industry peers.
The offset is Market Dynamics. Activity pressure is still negative at -0.15, despite a positive four-week improvement, and the signal state shows no fresh buy from that component. Sharemaestro’s next-week expectancy is positive at 56.37%, but the evidence is not one-sided: price and Relative Strength are constructive, while activity pressure is still asking for better confirmation.
Volume improved, with valuation and reversal risk still visible
Participation strengthened in the latest advance. Weekly volume was 3.8M shares, above the 13-week average of 2.6M and the 52-week average of 2.4M. The 1.4x ratio versus the 13-week norm is not an extreme accumulation read, but it is meaningful after the previous week’s 1.9M-share pullback and gives the 3.0% gain more weight than a low-volume bounce.
Risk remains centred on the premium to Fair Value, the negative activity-pressure read and 16 recent reversal markers in the smart-money tape. Weekly volatility is steady rather than elevated, with 13-week volatility at 3.6% versus a 52-week base of 3.5%. Over the past 52 weeks, CLH has logged 33 positive weeks and 19 negative weeks, with average up weeks of 2.7% and average down weeks of 2.9%. The next tests are whether activity pressure can move into positive territory, whether volume can push above the 1.5x confirmation line, and whether the stock can narrow the 6.9% gap to its 52-week high without losing the $288.3 Trend Line.
