Media mogul Rupert Murdoch, Facebook (FB) COO Sheryl Sandberg, and executives from Amazon (AMZN), Qorvo (QRVO) and Qualys (QLYS) were among the insiders making notable trades in the past week.

21st Century Fox

Rupert Murdoch, executive chairman of 21st Century Fox (FOXA), sold 53,349 of the entertainment company’s Class A shares for a value of around $1.4 million. Murdoch last sold shares of the company about a year ago.

The latest sale comes amid major changes in Murdoch’s media empire. Last month, Roger Ailes was ousted as Fox News’ CEO amid the fallout stemming from a sexual harassment lawsuit from former anchor Gretchen Carlson. Murdoch took over as the channel’s acting CEO.

Fox shares 3.35% for the week.

Facebook

COO Sheryl Sandberg has sold 138,337 shares of the social-media giant, according to a filing disclosed this week.

Facebook on Thursday said it would join up with Unity Technologies, which makes software to help others develop games, in an effort intended “to build new functionality into Unity that streamlines the process for exporting and publishing games onto Facebook.”

Shares lost 1.1% from a week ago.

Amazon

CFO Brian Olsavsky; Jeff Wilke, who is CEO of the e-commerce giant’s consumer unit; and Andrew Jassy, CEO of the company’s cloud division, all disclosed the sale of small amounts of shares this past week.

Amazon said this week that users of its virtual desktop, Amazon WorksSpaces, now have the option to pay to use the cloud service by the hour, potentially saving customers more money.

A company blog post said the feature would benefit part-time and traveling employees undertaking individual, short-term or collaborative projects.

Shares posted a 2% weekly decline.

Qorvo

CEO Robert Bruggeworth has sold 18,728 shares of the chipmaker across two separate disclosures this week.

A recent teardown of Samsung’s new Galaxy Note 7 phablet found that Qorvo had three chips in the device, less prominent than Qualcomm‘s (QCOM) presence.

Qorvo rallied 3% for the week, and Qualcomm rose 1.7%.

Qualys

CEO Philippe Courtot has sold 60,000 shares of the cloud security services provider, according to two disclosures this week.

Shares of the company, which got a bump this month following its second-quarter earnings report, surged 14.6% during the week.

Insider transactions don’t typically have a major impact on a stock or indicate major pending news. Rapid liquidation of all or most of an insider’s holdings, however, can affect a stock.
