Insider Buyers At Atomo Diagnostics Recover Some Losses, But Still Down AU$30k

Simply Wall St

Some of the losses seen by insiders who purchased AU$219.8k worth of Atomo Diagnostics Limited (ASX:AT1) shares over the past year were recovered after the stock increased by 10% over the past week. However, the purchase is proving to be a costly gamble, since losses made by insiders have totalled AU$30k since the time of purchase.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, logic dictates you should pay some attention to whether insiders are buying or selling shares.

The Last 12 Months Of Insider Transactions At Atomo Diagnostics

Over the last year, we can see that the biggest insider purchase was by insider Lin Xiaoyi for AU$220k worth of shares, at about AU$0.019 per share. That means that an insider was happy to buy shares at above the current price of AU$0.016. It's very possible they regret the purchase, but it's more likely they are bullish about the company. In our view, the price an insider pays for shares is very important. As a general rule, we feel more positive about a stock when an insider has bought shares at above current prices, because that suggests they viewed the stock as good value, even at a higher price. Lin Xiaoyi was the only individual insider to buy during the last year.

Insider Ownership

Looking at the total insider shareholdings in a company can help to inform your view of whether they are well aligned with common shareholders. I reckon it's a good sign if insiders own a significant number of shares in the company. Insiders own 9.8% of Atomo Diagnostics shares, worth about AU$1.2m, according to our data. But they may have an indirect interest through a corporate structure that we haven't picked up on. We do generally prefer see higher levels of insider ownership.

It is good to see the recent insider purchase. And an analysis of the transactions over the last year also gives us confidence. But we don't feel the same about the fact the company is making losses. On this analysis the only slight negative we see is the fairly low (overall) insider ownership; their transactions suggest that they are quite positive on Atomo Diagnostics stock.
