Allegion Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider purchase was by President John Stone for US$1.1m worth of shares, at about US$141 per share. That means that an insider was happy to buy shares at around the current price of US$149. Of course they may have changed their mind. But this suggests they are optimistic. If someone buys shares at well below current prices, it's a good sign on balance, but keep in mind they may no longer see value. The good news for Allegion share holders is that insiders were buying at near the current price.

Insider Ownership

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. Allegion insiders own about US$33m worth of shares. That equates to 0.3% of the company. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.
