Over the past year, many Clean Harbors, Inc. (NYSE:CLH) insiders sold a significant stake in the company which may have piqued investors' interest. When analyzing insider transactions, it is usually more valuable to know whether insiders are buying versus knowing if they are selling, as the latter sends an ambiguous message. However, shareholders should take a deeper look if several insiders are selling stock over a specific time period.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we would consider it foolish to ignore insider transactions altogether.

Clean Harbors Insider Transactions Over The Last Year

The Founder, Alan McKim, made the biggest insider sale in the last 12 months. That single transaction was for US$11m worth of shares at a price of US$212 each. So what is clear is that an insider saw fit to sell at around the current price of US$206. We generally don't like to see insider selling, but the lower the sale price, the more it concerns us. In this case, the big sale took place at around the current price, so it's not too bad (but it's still not a positive).
