Jay C. Horgen, President and CEO, sold 17,500 shares of Affiliated Managers Group at $338.27, reducing his non-derivative holdings from 222,206 shares to 204,706 shares (-7.9% vs pre-transaction holdings). The sale occurred when AMG traded -0.4% from its 52-week high of $338.07, and the stock has appreciated 11.2% over the prior 30 days and 19.9% over the prior 90 days. Horgen's prior two sales at AMG in August 2024 were followed by 30-day returns of +5.8% and +2.2%, respectively, and 90-day returns of +9.0% and +8.4%—neither sale preceded a decline, yielding a 0 of 2 well-timed rate at the 90-day mark. The company reports a P/E of 11.78 and net income of $110,400,000.00 against quarterly revenue of $544,900,000.00, suggesting stable profitability, though annual revenue growth stands at +1.6%.

Director Annette Franqui buys 750 AMG shares at $304.88; holdings rise 61.9% to 1,962 shares

Annette Franqui purchased 750 shares of AMG at $304.88 on 2026-06-01, increasing her holdings by 61.9% from 1,212 to 1,962 shares. The purchase occurred near the 52-week high, with the stock currently trading at $311.61, down 6.9% from its 52-week peak of $334.78. Across Franqui's cross-ticker open-market trading history, her prior buy has delivered a 90-day average return of +7.4% with a 100.00% win rate, though this limited track record applies across all tickers rather than specifically at AMG. The company's P/E of 10.91 and recent quarterly net income of $110,400,000.00 on revenue of $544,900,000.00 provide a valuation backdrop for the decision.

Director Ryan Christopher sells 3,402 AMG shares for $1.04M, reducing stake by 76% near recent highs.

Director Ryan David Christopher sold a substantial portion of his holdings in Affiliated Managers Group, divesting roughly three-quarters of his stake in a single transaction. The sale occurred while the stock was trading near its recent highs but down modestly from peak levels. The company itself remains solidly profitable with modest revenue growth and a reasonable valuation, suggesting the transaction reflects personal portfolio management rather than fundamental concerns about AMG's business. Christopher has no history of open-market buying activity—his prior filings show only stock-compensation transactions—making this a material disposition that simplifies his direct equity exposure to the company. Without additional context on his overall wealth, investment strategy, or board-level discussions, the large sale warrants monitoring to see whether other directors or officers follow suit or if this represents an isolated liquidity event.

Director Cates Staley buys 1,500 AMG shares at open market; stock trades below 52-week high while company remains profitable.

Director Cates Staley purchased 1,500 shares of AMG in open-market trading, significantly increasing his stake by roughly one-third. The timing is noteworthy: while the stock trades somewhat below its recent high, it has rallied sharply over the past month, suggesting Staley is buying after a near-term advance rather than catching a falling knife. More importantly, Staley's purchase occurs at a moment when the company demonstrates solid financial health—profitable operations with healthy margins and a reasonable valuation multiple—providing fundamental support for his conviction. As a director with governance responsibility, his decision to deploy personal capital into AMG shares adds credibility to management's public stewardship and suggests he sees value in the company's prospects despite recent gains.

President/COO Thomas M. Wojcik sold 8,000 shares at $286.30; stock now -14.9% from 52-week high, down -7.8% in 30 days

Wojcik sold 8,000 shares (a -4.8% reduction in holdings) at $286.30 on 2026-03-06, bringing his position to 159.5K shares. The stock has since declined -7.8% over the past 30 days and trades -14.9% below its 52-week high of $330.75, with current price at $281.53. His prior two sales at AMG yielded positive 90-day returns (+4.7% and +8.4%), indicating historically poor timing at this ticker—the stock has risen after his prior sales. Across all his tickers, his 2 prior open-market sells averaged a 90d well-timed rate of 0.00%, suggesting no pattern of prescient timing. The company's fundamentals remain solid (P/E 10.20, $212.4M net income on $528.0M quarterly revenue, +1.6% annual growth), and the recent price weakness represents an opportunity rather than a fundamental deterioration.

General Counsel Kavita Padiyar sold 2,200 shares of AMG at $278.24; stock now at $281.53, -14.9% from 52-week high.

Padiyar, as General Counsel, sold 2,200 shares for $612,128.00, reducing holdings from 44,872 shares to 42,672 shares. At the sale price of $278.24, the stock was positioned between its 52-week low of $143.35 and high of $330.75, and is now trading at $281.53, modestly above the transaction price. AMG trades at a P/E of 10.20 with $528.0M in latest quarterly revenue and $212.4M in net income, suggesting valuation compression relative to earnings generation. The sale represents a routine portfolio adjustment by a senior executive with substantial remaining holdings equal to 42.7K shares post-transaction.

AMG President/COO Wojcik sells 16,000 shares ($3.7M) at $231.03; stock up 9.8% in 30 days, 26.6% in 90 days

Wojcik sold 16,000 shares (representing 9.2% of his pre-transaction holdings) at $231.03 on September 9, 2025, bringing his stake to 158,710 shares. The sale occurred near the 52-week high ($233.05), with the stock currently trading at $231.96. His cross-ticker track record shows 1 prior open-market sale with an average 90-day return of +8.4%, indicating prior sales have been poorly timed; at AMG specifically, his one prior sale on 2024-08-16 returned +8.4% over 90 days. The stock has appreciated 9.8% in the past 30 days and 26.6% over 90 days, reflecting strong recent momentum despite flat annual revenue growth (-0.8%) and modest valuation metrics (P/E 14.90, $6.6B market cap). The transaction reflects a partial reduction in an otherwise substantial executive position held by the company's President and COO.

Head of Affiliate Investments sold 8,622 shares of AMG at $172.89; retains 128,457 shares post-sale.

Jamal Rizwan M, Head of Affiliate Investments at Affiliated Managers Group, executed a sale of 8,622 shares at $172.89 on 2024-08-16, reducing his holdings by 6.3% to 128,457 shares.

The company faces material headwinds with annual revenue declining 11.7% year-over-year, though near-term price momentum has been positive (+7.5% over 90 days). The insider retains a substantial position (128.5K shares), indicating continued ownership stake in the business.

AMG COO Thomas Wojcik sold 4,786 shares at $172.71 (−5.4% of holdings); stock trades −8.3% from 52-week high.

Chief Operating Officer Thomas Wojcik sold 4,786 shares of Affiliated Managers Group at $172.71, reducing his holdings from 89,178 to 84,392 shares. The sale occurred when AMG's stock was trading −8.3% below its 52-week high of $185.62, amid a backdrop of declining annual revenue (−11.7% year-over-year) and a low valuation (P/E of 7.94). The modest reduction (−5.4% of pre-transaction holdings) combined with the company's challenged growth trajectory and depressed stock price relative to recent highs presents a data point worth monitoring in the context of broader insider positioning and sentiment.
