The fact that multiple Lennox International Inc. (NYSE:LII) insiders offloaded a considerable amount of shares over the past year could have raised some eyebrows amongst investors. 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 insider transactions are not the most important thing when it comes to long-term investing, we would consider it foolish to ignore insider transactions altogether.

Lennox International Insider Transactions Over The Last Year

The Executive VP & Chief HR Officer, Daniel Sessa, made the biggest insider sale in the last 12 months. That single transaction was for US$1.8m worth of shares at a price of US$368 each. So it's clear an insider wanted to take some cash off the table, even below the current price of US$491. 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. While insider selling is not a positive sign, we can't be sure if it does mean insiders think the shares are fully valued, so it's only a weak sign. We note that the biggest single sale was only 12% of Daniel Sessa's holding.

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. I reckon it's a good sign if insiders own a significant number of shares in the company. Lennox International insiders own about US$560m worth of shares (which is 3.2% of the company). Most shareholders would be happy to see this sort of insider ownership, since it suggests that management incentives are well aligned with other shareholders.
