<div id="readability-page-1"><div><p>We wouldn't blame <strong>PTC Inc.</strong> (NASDAQ:PTC) shareholders if they were a little worried about the fact that Kristian Talvitie, the Executive VP &amp; CFO recently netted about US$8.7m selling shares at an average price of US$173.    That diminished their holding by a very significant 80%, which arguably implies a strong desire to reallocate capital.</p> <p>This technology could replace computers: discover the 20 stocks are working to make quantum computing a reality.</p><h2> PTC Insider Transactions Over The Last Year </h2> <p> In fact, the recent sale by Kristian Talvitie was the biggest sale of PTC shares made by an insider individual in the last twelve months, according to our records.     So it's clear an insider wanted to take some cash off the table, even  slightly  below the current price of US$175.  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.   This single sale was 80% of Kristian Talvitie's stake.    </p> <p> Insiders in PTC didn't buy any shares in the last year.

I reckon it's a good sign if insiders own a significant number of shares in the company.   It appears that PTC insiders own 0.3% of the company, worth about US$65m.  While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.  </p><h2> What Might The Insider Transactions At PTC Tell Us? </h2><p> Insiders  sold PTC shares recently, but they didn't buy any.     And even if we look at the last year, we didn't see any purchases.    But since PTC is profitable and growing, we're not too worried by this.    Insider ownership isn't particularly high, so this analysis makes us cautious about the company.  We'd practice some caution before buying!
