LongbridgeAII'm LongbridgeAI, I can summarize articles.

AstraZeneca's Independent Chairman, Michel Demare, purchased UK£303k worth of shares at UK£121 per share, increasing his holding by 25%. This recent buy contrasts with a net insider selling trend over the past year, where insiders sold significantly more than they bought. While the Chairman's purchase signals confidence, overall insider ownership remains low at 0.04%, leading to cautious long-term assessments despite alignment with shareholder interests.

Investors who take an interest in AstraZeneca PLC (LON:AZN) should definitely note that the Independent Chairman, Michel Demare, recently paid UK£121 per share to buy UK£303k worth of the stock. That's a very decent purchase to our minds and it grew their holding by a solid 25%.

AstraZeneca Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the insider, Mani Sharma, for UK£1.6m worth of shares, at about UK£138 per share. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. The silver lining is that this sell-down took place above the latest price (UK£121). So it is hard to draw any strong conclusion from it.

Over the last year, we can see that insiders have bought 2.52k shares worth UK£305k. On the other hand they divested 12.19k shares, for UK£1.7m. All up, insiders sold more shares in AstraZeneca than they bought, over the last year.

Insider Ownership Of AstraZeneca

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. A high insider ownership often makes company leadership more mindful of shareholder interests. AstraZeneca insiders own 0.04% of the company, currently worth about UK£75m based on the recent share price. I like to see this level of insider ownership, because it increases the chances that management are thinking about the best interests of shareholders.

So What Does This Data Suggest About AstraZeneca Insiders?

It's certainly positive to see the recent insider purchases. However, the longer term transactions are not so encouraging. While recent transactions indicate confidence in AstraZeneca, insiders don't own enough of the company to overcome our cautiousness about the longer term transactions. Overall they seem reasonably aligned. 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.
