Cytek Biosciences Insiders May Regret Not Buying More, Market Cap Hits US$510m

Insiders who bought Cytek Biosciences, Inc. (NASDAQ:CTKB) stock in the last 12 months were richly rewarded last week. The company's market value increased by US$92m as a result of the stock's 19% gain over the same period. As a result, the stock they originally bought for US$97.3k is now worth US$158.9k.

Although we don't think shareholders should simply follow insider transactions, we do think it is perfectly logical to keep tabs on what insiders are doing.

The Last 12 Months Of Insider Transactions At Cytek Biosciences

In the last twelve months, the biggest single purchase by an insider was when Chief Financial Officer William McCombe bought US$97k worth of shares at a price of US$2.78 per share. We do like to see buying, but this purchase was made at well below the current price of US$4.54. Because the shares were purchased at a lower price, this particular buy doesn't tell us much about how insiders feel about the current share price.

Insider Ownership

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. Usually, the higher the insider ownership, the more likely it is that insiders will be incentivised to build the company for the long term. Cytek Biosciences insiders own about US$47m worth of shares. That equates to 9.3% of the company. While this is a strong but not outstanding level of insider ownership, it's enough to indicate some alignment between management and smaller shareholders.
