Over the past year, many Westinghouse Air Brake Technologies Corporation (NYSE:WAB) insiders sold a significant stake in the company which may have piqued investors' interest. Knowing whether insiders are buying is usually more helpful when evaluating insider transactions, as insider selling can have various explanations. However, if numerous insiders are selling, shareholders should investigate more.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we do think it is perfectly logical to keep tabs on what insiders are doing.

The Last 12 Months Of Insider Transactions At Westinghouse Air Brake Technologies

The CEO, President & Director, Rafael Santana, made the biggest insider sale in the last 12 months. That single transaction was for US$8.2m worth of shares at a price of US$105 each. That means that even when the share price was below the current price of US$113, an insider wanted to cash in some shares. When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. Please do note, however, that sellers may have a variety of reasons for selling, so we don't know for sure what they think of the stock price. This single sale was 52% of Rafael Santana's stake.
