Some corporate insiders cashed in on the recent stock market rebound, making multimillion-dollar sales last week, including executives at two leading tech companies.

Insider transactions are tracked by many professional investors and fund managers. The idea is that when board members or managers are selling a stock, it might express a lack of confidence in the business, and vice versa.

Sometimes sales are part of prefiled plans, used in estate and trust management, but there have been several notable transactions in recent days that did not fall into this category, according to VerityData and securities filings.

One came from CrowdStrike president Michael Sentonas, who sold nearly $12 million worth of stock on June 11. Shares of CrowdStrike were up about 40% year to date entering Monday.

Another tech executive who lightened up on his own company’s stock was Broadcom president Charlie Kawwas, who sold $2.5 million worth of shares on June 11. Broadcom has not been as hot as CrowdStrike, but the stock was up about 9% this year as of Monday, after having doubled in each of the past two years.

Outside of tech, one particularly massive stock sale came from Ralph Lauren, executive chair of the company that bears his name. He sold more than $71 million worth of stock. Ralph Lauren’s stock price was up more than 17% this year as of Monday. A footnote in the securities filings said the sale was “made in connection with a long-term strategy for investment diversification,” though it was not part of a typical 10b5-1 plan used to schedule insider sales.

Here are several other notable insider sales from the past week:

• HealthEquity Chief Technology Officer Elimelech Rosner sold 71,000 shares for a total of $7.98 million on June 9. The sale reduced Rosner’s reported vested equity by more than 50%.

• Quantum Computing Chief Financial Officer Christopher Boehmler sold about 272,400 shares for a total of $4.59 million. The transactions were conducted June 9-11 and represented about 25% of his holdings, including equity and vested options. QUBT shares were up 250% over the prior three months.

• Pilgrim’s Pride CEO Fabio Sandri sold 70,000 shares for a total of $3.21 million. The transaction was made on June 9.

• Fair Isaac CFO Steven Weber sold 1,000 shares for a total of $1.74 million. The transaction came June 9 and shares were up just 3% over the prior three months.
