The Last 12 Months Of Insider Transactions At Annexon

In fact, the recent purchase by Jung Choi was the biggest purchase of Annexon shares made by an insider individual in the last twelve months, according to our records. That implies that an insider found the current price of US$4.49 per share to be enticing. 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. If someone buys shares at well below current prices, it's a good sign on balance, but keep in mind they may no longer see value. The good news for Annexon share holders is that an insider was buying at near the current price. Jung Choi was the only individual insider to buy shares in the last twelve months.

Insider Ownership

For a common shareholder, it is worth checking how many shares are held by company insiders. A high insider ownership often makes company leadership more mindful of shareholder interests. Insiders own 1.0% of Annexon shares, worth about US$6.8m, according to our data. We do generally prefer see higher levels of insider ownership.

So What Does This Data Suggest About Annexon Insiders?

It's certainly positive to see the recent insider purchase. We also take confidence from the longer term picture of insider transactions. However, we note that the company didn't make a profit over the last twelve months, which makes us cautious. While the overall levels of insider ownership are below what we'd like to see, the history of transactions imply that Annexon insiders are reasonably well aligned, and optimistic for the future. While it's good to be aware of what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision.
