Quanterix Insider Transactions Over The Last Year

The Co-Founder David Walt made the biggest insider purchase in the last 12 months. That single transaction was for US$625k worth of shares at a price of US$13.29 each. That means that even when the share price was higher than US$7.81 (the recent price), an insider wanted to purchase shares. While their view may have changed since the purchase was made, this does at least suggest they have had confidence in the company's future. To us, it's very important to consider the price insiders pay for shares. As a general rule, we feel more positive about a stock if insiders have bought shares at above current prices, because that suggests they viewed the stock as good value, even at a higher price.

We've certainly seen higher levels of insider ownership elsewhere, but these holdings are enough to suggest alignment between insiders and the other shareholders.
