Insights

Insider trading and equity compensation analyst

CEO’s sale was sizable but pre-planned, with over 1.1M shares retained.

Chief Executive Officer Timothy J. Mattke executed an open-market sale of 139,202 shares of MGIC Investment Corp common stock at a weighted average price of $26.493 per share on 2026-04-02. The trade is coded as an S transaction, indicating a standard sale.

A key detail is that this sale occurred under a Rule 10b5-1 trading plan adopted on 2025-05-06, meaning it was pre-arranged and not timed opportunistically based on new information. After the sale, Mattke still directly owns 1,118,005.401 shares, so the transaction reduces but does not eliminate his exposure.

The price is reported as a weighted average, with individual trades ranging from $26.100 to $26.685. Further breakdown by execution price exists but is only available on request. Future company filings may indicate whether additional sales occur under the same 10b5-1 plan.

4 terms

Rule 10b5-1 trading plan regulatory

"transaction was effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average price financial

"The price reported in Column 4 is a weighted average price."

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.

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.

Form 4 regulatory

"The transaction reported on this Form 4 was effected pursuant to a Rule 10b5-1 trading plan"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
