MTG President & COO Salvatore A Miosi sells 30,000 shares at $28.23 under scheduled 10b5-1 plan

Salvatore A Miosi executed a sale of 30,000 shares of MGIC INVESTMENT CORP for $846,900.00, reducing his holdings from 560,951 shares to 530,951 shares. This transaction is part of a pre-arranged 10b5-1 trading plan, meaning it was scheduled rather than discretionary. Across his prior five trades at MTG, outcomes have been mixed: three of the four measurable sales saw negative 90-day returns (-6.7%, -3.7%, and -9.0%), while one showed a +2.9% 30-day return despite a -6.6% 90-day outcome. The company itself shows modest fundamentals with $297.1M quarterly revenue, $165.3M net income, and a P/E of 8.30, suggesting a valuation-conscious market positioning.

CFO Nathaniel Colson sells 20,000 MTG shares at $27.10 (10b5-1 plan); retains 341,225 shares post-transaction

Nathaniel H Colson, EVP, CFO & CRO of MGIC Investment Corp, sold 20,000 shares at $27.10 on 2026-06-25 under a pre-arranged 10b5-1 trading plan, reducing his holdings to 341,225 shares from 361,225 shares. As a scheduled transaction, this sale does not reflect discretionary timing decisions. The stock currently trades at $27.84, within its 52-week range of $24.69–$29.97, up 7.7% over the past 30 days and 8.2% over 90 days. MTG's valuation remains compressed at a P/E of 8.19 with $297.1M quarterly revenue and $165.3M net income; annual growth stands at +0.5%.

MTG President & COO Salvatore A Miosi sold 30,000 shares at $25.38 via scheduled 10b5-1 plan

Salvatore A Miosi executed a sale of 30,000 shares at $25.38 as part of a pre-arranged 10b5-1 trading plan, reducing his holdings from 590,951 shares to 560,951 shares. This is a scheduled transaction rather than a discretionary decision, limiting its evidentiary value as a signal of insider conviction. Examining his same-ticker history at MTG, five prior sells have uniformly resulted in negative subsequent returns: -2.9% and -6.7% (30d/90d) on 2026-03-02; -1.3% and -3.7% on 2026-02-02; -7.6% and -9.0% on 2026-01-02; +2.9% and -6.6% on 2025-12-01; and +2.8% and -2.2% on 2025-11-03. The current stock price of $25.55 is -14.8% from the 52-week high of $29.97 and down -4.5% over the trailing 30 days, placing the transaction within a period of moderate weakness. The company maintains a low P/E of 7.51 with substantial profitability ($165.3M net income on $297.1M quarterly revenue), but annual revenue growth is minimal at +0.5%.

Paula C Maggio (EVP/General Counsel) sold 20,937 shares of MTG at $25.55 under pre-arranged 10b5-1 plan; holds 169,619 shares post-sale.

Paula C Maggio sold 20,937 shares (20.9K shares) at $25.55 on 2026-05-29 under a pre-arranged 10b5-1 trading plan adopted on 2026-02-27, reducing her holdings from 190,556 shares to 169,619 shares. Since this transaction is scheduled rather than discretionary, no timing inference about the executive's conviction or market view is appropriate. At the same ticker, her prior four sales on 2025-05-30, 2025-08-04, 2025-10-31, and 2026-02-06 produced mixed returns: her 2025-08-04 and 2025-05-30 sales showed positive 90-day returns of +3.3% and +4.5% respectively, while her 2025-10-31 and 2026-02-06 sales showed negative 90-day returns of -1.6% and -3.4%. MGIC trades at a P/E of 7.37, and the stock is currently -16.4% from its 52-week high and -4.6% over the past 30 days.

MTG CEO Timothy J. Mattke sold 139,202 shares at $26.49; retains 1,118,005 shares post-sale

Timothy J. Mattke, Chief Executive Officer of MGIC INVESTMENT CORP, sold 139,202 shares at $26.49 on 2026-04-02 for $3,687,878.59, reducing his holdings by -11.1% to 1,118,005 shares. The transaction occurred near the lower end of the 52-week range ($22.43–$29.86), with the stock -11.2% from its 52-week high and down 9.0% over 90 days. His cross-ticker track record shows 8 prior open-market sells with an average 90-day return of +7.4% and a well-timed rate of 0.00%, meaning prior sales occurred before stock appreciation rather than declines. At MTG specifically, his five prior January sales all occurred too recently for 90-day outcomes to be measurable. The company trades at a P/E of 7.82 with $304.5M quarterly revenue and $191.1M net income, but annual revenue growth is minimal at +0.5%. The sale represents a substantial reduction in his equity stake by a sitting executive during a period of modest positive stock momentum.

MTG President & COO sells 30,000 shares at $27.04; stock now $26.72, off 10.5% from 52-week high

Salvatore A Miosi, President & COO of MGIC Investment Corp, sold 30,000 shares (30.0K shares) at $27.04 on 2026-03-02, reducing his holdings from 761,203 shares to 731,203 shares (-3.9%). At his same-ticker MTG trades, 2 of 3 prior sells that have measurable 90-day outcomes were well-timed (stock declined after the sale). The current price of $26.72 is -10.5% from the 52-week high of $29.86, suggesting the stock has faced downward pressure since the transaction. His cross-ticker track record shows a 28.57% well-timed rate on prior sells, indicating above-average timing accuracy historically, though this metric spans multiple stocks and does not necessarily predict MTG-specific timing. The fundamental valuation remains modest (P/E of 7.88) and the company posted solid recent quarterly results ($191.1M net income on $304.5M revenue), but the pattern of repeated sales at this ticker over five months, combined with recent price depreciation, merits monitoring of his conviction level and any forward guidance that might explain the disposition activity.

Maggio (EVP & General Counsel) sold 20,000 shares of MTG at $27.51 on 2026-02-06; stock now $26.62, down 10.8% from 52-week high.

Maggio sold 20,000 shares of MGIC INVESTMENT CORP at $27.51, reducing holdings by 14.8% to 114,688 shares. The sale occurred at a price above the current $26.62 level, and MTG has declined 10.8% from its 52-week high of $29.86 and 8.2% over the past 30 days. Maggio's prior sales at MTG show mixed timing: 1 of 3 prior sells were well-timed at the 90-day mark, with returns ranging from -1.6% to +5.7% post-sale. The company shows solid fundamentals with $304.5M quarterly revenue, $191.1M net income, 4.6% annual revenue growth, and a low P/E of 7.90, suggesting the sell occurs amid reasonable valuations rather than distressed circumstances. The sale reflects a significant reduction in exposure but does not indicate urgent concern given the otherwise stable financial metrics.

MTG President & COO Salvatore sells 30.0K shares at $27.27; stock down 12.5% from high, down 10.4% in 30 days.

Salvatore A Miosi, President & COO of MGIC Investment Corp, sold 30,000 shares at $27.27 on 2026-02-02, reducing holdings by 6.2% to 454.2K shares. The stock has declined 12.5% from its 52-week high of $29.86 and is down 10.4% over the past 30 days, suggesting he sold into weakness rather than at peak valuations. His prior trades at MTG show mixed timing—only 1 of 3 measurable 90-day outcomes were well-timed (negative returns after the sale), and his most recent MTG sale on 2026-01-02 already shows a -7.6% 30-day return. At a P/E of 7.75 with strong Q-end net income of $191.1M, the fundamentals remain stable, but the pattern of selling as the stock declines warrants observation of whether management sees deteriorating near-term conditions.

CEO Mattke sells 139,203 shares for $3,689,849.65 in 6 transactions via scheduled 10b5-1 plan

Timothy J. Mattke, CEO of MGIC Investment Corp, executed 6 separate sales totaling 139,203 shares for $3,689,849.65 on 2026-01-13 under a pre-arranged 10b5-1 trading plan, reducing his holdings from 961,791 shares to 822,588 shares. Because this transaction is part of a scheduled 10b5-1 plan rather than discretionary, it reflects a predetermined program established in advance and does not provide insight into the CEO's current conviction regarding the company's stock. The blended average sale price across the six transactions was $26.51. Post-transaction, Mattke retains significant holdings of 822,588 shares, maintaining material skin in the game despite the reduction.

MTG President Miosi sells 30,000 shares at $29.13; stock at $29.56 near 52-week high, up 5.6% in 30 days

Salvatore Miosi, President & COO, sold 30,000 shares (23.2% of pre-transaction holdings) at $29.13, reducing his stake from 129,401 to 99,401 shares. The sale occurred near the stock's 52-week high of $29.86 (just 1.0% below), following strong recent momentum of +5.6% over 30 days and +9.3% over 90 days. His prior five sales at MTG show mixed timing outcomes: the last three measurable 90-day periods posted gains of +5.1%, +3.1%, and +4.9%, and crucially, 0 of 3 were well-timed (none saw the stock decline after the sale). His cross-ticker selling track record is similarly uninspiring, with a 0.00% well-timed rate on 7 prior sells averaging +4.4% returns over 90 days post-sale—indicating his past sales have generally occurred before stock rallies rather than declines. The company trades at a low P/E of 8.77 with solid fundamentals (net income $191.1M on revenue of $304.5M, +4.6% annual growth), suggesting the stock has upside potential, yet the sales pattern suggests the insider has systematically sold into strength rather than positioned defensively before weakness.
