We wouldn't blame Comfort Systems USA, Inc. (NYSE:FIX) shareholders if they were a little worried about the fact that Brian Lane, the CEO, President & Director recently netted about US$4.9m selling shares at an average price of US$330. However, it's crucial to note that they remain very much invested in the stock and that sale only reduced their holding by 7.0%.

Comfort Systems USA Insider Transactions Over The Last Year

Notably, that recent sale by CEO, President & Director Brian Lane was not the only time they sold Comfort Systems USA shares this year. Earlier in the year, they fetched US$183 per share in a -US$7.3m sale. So it's clear an insider wanted to take some cash off the table, even below the current price of US$331. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. 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. It is worth noting that this sale was only 16% of Brian Lane's holding.
