The Last 12 Months Of Insider Transactions At PDF Solutions

In the last twelve months, the biggest single purchase by an insider was when Co-Founder John Kibarian bought US$1.1m worth of shares at a price of US$22.80 per share. So it's clear an insider wanted to buy, even at a higher price than the current share price (being US$19.70). Their view may have changed since then, but at least it shows they felt optimistic at the time. In our view, the price an insider pays for shares is very important. It is generally more encouraging if they paid above the current price, as it suggests they saw value, even at higher levels.

In the last twelve months insiders purchased 61.50k shares for US$1.4m. On the other hand they divested 18.78k shares, for US$597k.
