In the last year, many Arcellx, Inc. (NASDAQ:ACLX) insiders sold a substantial stake in the company which may have sparked shareholders' attention. When evaluating insider transactions, knowing whether insiders are buying is usually more beneficial than knowing whether they are selling, as the latter can be open to many interpretations. However, if numerous insiders are selling, shareholders should investigate more.

Although we don't think shareholders should simply follow insider transactions, we would consider it foolish to ignore insider transactions altogether.

Arcellx Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the Chairman of the Board, Rami Elghandour, for US$2.4m worth of shares, at about US$64.46 per share. That means that even when the share price was below the current price of US$83.51, an insider wanted to cash in some shares. We generally consider it a negative if insiders have been selling, especially if they did so below the current price, because it implies that they considered a lower price to be reasonable. However, while insider selling is sometimes discouraging, it's only a weak signal. This single sale was just 29% of Rami Elghandour's stake.

Insider Ownership

For a common shareholder, it is worth checking how many shares are held by company insiders. I reckon it's a good sign if insiders own a significant number of shares in the company. It appears that Arcellx insiders own 0.2% of the company, worth about US$11m. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.

So What Does This Data Suggest About Arcellx Insiders?

The fact that there have been no Arcellx insider transactions recently certainly doesn't bother us. Still, the insider transactions at Arcellx in the last 12 months are not very heartening. But it's good to see that insiders own shares in the company. So these insider transactions can help us build a thesis about the stock, but it's also worthwhile knowing the risks facing this company.
