About Michael J. Katz's insider trades
Michael J. Katz is Chief Bus. and Prod. Officer at T-Mobile US (TMUS). Since Aug 10, 2022, Michael has reported no open-market purchases and 15 sales worth $11.7M on SEC Form 4. In the last 12 months: 2 sales ($1.5M).
13 sales (64% of the value sold) were made under a Rule 10b5-1 trading plan, which is set up months in advance and runs on a schedule, so they say little about how the insider sees the stock today.
Their filings also include shares withheld for taxes (9 filings), grants and awards (8 filings). These aren't open-market trades and aren't counted above.
How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every TMUS insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
