Clean Harbors should undergo some profit-taking after the rebound in recent sessions.

The valuation of the company is not attractive with a P/E ratio of 30x in 2015. Moreover, analysts covering the stock are downgrading severly their EPS estimates.

Graphically, the stock went through a period of rebound in recent sessions towards the USD 57.2 medium-term resistance. The share should consolidate near this area. It could act as a stopping point of the upward movement. This scenario suggests a return towards the USD 51.9 support area which will be the bearish objective.

Therefore, the most aggressive investors could take a short position on the stock and target USD 51.9. A stop loss will be placed above the current resistance.
