Have Constellation Software Insiders Been Selling Stock?

We wouldn't blame Constellation Software Inc. (TSE:CSU) shareholders if they were a little worried about the fact that Barry Symons, a company insider, recently netted about CA$8.3m selling shares at an average price of CA$3,304. However, it's crucial to note that they remain very much invested in the stock and that sale only reduced their holding by 1.9%.

Constellation Software Insider Transactions Over The Last Year

The Founder & Director, Mark Leonard, made the biggest insider sale in the last 12 months. That single transaction was for CA$66m worth of shares at a price of CA$4,698 each. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. The silver lining is that this sell-down took place above the latest price (CA$3,202). So it is hard to draw any strong conclusion from it.

Happily, we note that in the last year insiders paid CA$2.8m for 765.00 shares. On the other hand they divested 19.85k shares, for CA$90m. In total, Constellation Software insiders sold more than they bought over the last year.
