This is the public record of open-market stock transactions Matthew J. Murphy has reported to the SEC on Form 4 as Chairman of the Board and CEO of Marvell Technology, Inc. (MRVL).

Questions about this record

How many shares has Matthew J. Murphy bought and sold?

Matthew J. Murphy has disclosed 8 Form 4 transactions in the record we track, from Sep 25, 2025 to Sep 15, 2026: 7 sales worth $12,557,025 and 1 open-market purchase worth $1,048,424. Each figure is the reported share count multiplied by the reported price, so these are exact disclosed amounts, not estimates.

Is Matthew J. Murphy selling a bearish signal?

Not on its own. Insiders sell for many reasons that have nothing to do with a view on the stock — diversification, taxes, estate planning, or a pre-scheduled plan set up months earlier. Of the 7 sales on this record, 7 were made under a Rule 10b5-1 plan and 0 were automatic tax withholding on vesting shares, leaving 0 that were the insider's own discretionary decision (worth $0). Buying is the cleaner signal, because there is only one reason to buy. This page is a record, not a recommendation.

What is Matthew J. Murphy's role?

Matthew J. Murphy files as Chairman of the Board and CEO of Marvell Technology, Inc. (MRVL). That role is taken from the Form 4 filings themselves. A Form 4 is filed with the SEC within two business days of an insider buying or selling their own company's stock.

What was Matthew J. Murphy's largest single transaction?

The largest single transaction on record is a sell of 30,000 shares of MRVL at $98.70, worth $2,961,000, filed Mar 26, 2026.

How current is this record?

The most recent Form 4 here was filed Sep 15, 2026. Insiders have two business days to file after a trade, so this is close to real time, but it is a record of what has been disclosed, not a statement of what Matthew J. Murphy currently holds. Amounts are open-market and plan transactions reported on Form 4; grants and option exercises are not counted as buys.
