On July 15, just a few days before the Microsoft-CrowdStrike global tech outage caused by a corrupted anti-virus update (or so we are told), CrowdStrike Chief Security Officer Shawn Henry sold 4,000 shares of CrowdStrike Holdings Inc (NASDAQ: CRWD), a recent SEC filing shows.

After the sale, Henry now owns 183,091 shares of the company, which specializes in cloud-delivered protection of endpoints, cloud workloads, identity and data, according to Yahoo! Finance. CrowdStrike exists to prevent the types of breaches that occurred over the weekend with the crippling of global tech platforms.

Over the past year, Henry unloaded 85,986 shares of CrowdStrike at various intervals. During the same time period, Henry did not make a single purchase of CrowdStrike shares.

Henry is not the only person at CrowdStrike who followed this same MO. A total of 48 insiders at CrowdStrike sold shares over the past year. Not a single one of them made any share purchases during the same time period.

Are CrowdStrike insiders doing insider trading?

The day of Henry's share sale, the price of a CrowdStrike share was $371.32, which gives the company a market cap of $89.81 billion. The company's price-to-earnings ratio is an astounding 696.32, which is significantly higher than the industry median of 27.16.

CrowdStrike stock's GF value is estimated at around $346.82, leading to a price-to-GF-Value ratio of 1.07. In layman's terms, the stock is considered by the markets to be Fairly Valued.

Those who hold CrowdStrike shares may want to take note of these routine stock sales from Henry and other insiders who are slowly offloading their shares and not buying any more of them. What does this mean for the future of CRWD's stock price?
