Insights

Equity analyst

Pre-planned trust sale of 10,000 Marvell shares; sizable indirect stake remains.

The transaction shows a family trust linked to Marvell’s President and COO selling 10,000 common shares in the open market at a weighted average price of $205.87. This is an indirect holding, reported as "By Trust" rather than personal direct ownership.

The sale was made under a pre-arranged Rule 10b5-1 trading plan adopted on January 5, 2026, suggesting it was scheduled in advance rather than timed opportunistically. Such plans are commonly used to diversify or manage liquidity while reducing concerns about trading on nonpublic information.

After the sale, the family trust still holds 237,392 shares, so most of the indirect position remains in place. Subsequent company filings may provide further context if additional 10b5-1 plan sales occur or if there are changes to the executive’s overall equity exposure.

4 terms

Rule 10b5-1 Plan regulatory

"Sales were made pursuant to a 10b5-1 Plan adopted by the Reporting Person on January 5, 2026."

A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.

weighted average price financial

"The price reported is a weighted average price rounded to the nearest cent."

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

Family Trust financial

"Shares held by the Christopher R. Koopmans and Heather J. Koopmans Family Trust."

open-market sale financial

"transaction_action: open-market sale"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
