Some Vicor Corporation (NASDAQ:VICR) shareholders may be a little concerned to see that the Corporate VP & Director, Claudio Tuozzolo, recently sold a substantial US$2.8m worth of stock at a price of US$271 per share. That's a big disposal, and it decreased their holding size by 44%, which is notable but not too bad.

Vicor Insider Transactions Over The Last Year

In fact, the recent sale by Claudio Tuozzolo was the biggest sale of Vicor shares made by an insider individual in the last twelve months, according to our records. So what is clear is that an insider saw fit to sell at around the current price of US$249. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. Given that the sale took place at around current prices, it makes us a little cautious but is hardly a major concern.

Insider Ownership Of Vicor

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. It's great to see that Vicor insiders own 47% of the company, worth about US$5.6b. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.
