Executive VP Peterson sells 10,000 SEIC shares at $90.00 for $900,000; stock now $91.05

Peterson Michael, Executive Vice President at SEI Investments, sold 10,000 shares (10.0K shares) at $90.00 on 2026-04-23 for $900,000, reducing his holdings by 33.2% from 30,148 to 20,148 shares. The sale occurred near the 52-week high ($93.80), with the stock currently at $91.05 and up 16.2% over the past 30 days. His cross-ticker track record shows 8 prior sells averaging +0.7% return at 30 days and +2.1% at 90 days, with a 90-day well-timed rate of 37.50%. At SEIC specifically, Peterson's 5 prior sales show mixed outcomes: 2 of 5 were well-timed at 90 days, with the most recent two sales (2025-11-12 and 2025-08-07) both negative at 90 days. The company's fundamentals remain solid, with $578.5M quarterly revenue, $164.2M net income, and a P/E of 13.37, suggesting the sale reflects position sizing rather than fundamental concern.

Sharma sold 25.0K SEIC shares (38.6% reduction) at blended $90.12 on 2026-04-23.

Sanjay Sharma executed 2 separate sales totaling 25,000 shares for $2,253,013.35, reducing his SEIC holdings from 64,828 to 39,828 shares. The sales occurred at a blended average price of $90.12, near the current price of $91.05 and within the recent 52-week range. Sharma's same-ticker history at SEIC shows 2 prior sells (2025-05-14 and 2024-02-12) with mixed post-transaction returns, neither well-timed on a 90-day basis. The fundamental backdrop is stable—SEIC reported $578.5M revenue growth of +8.1% year-over-year with a P/E of 13.37—providing no obvious distress signal. The sale represents a material reduction in his stake but absent additional context (such as scheduled plan language or external events), the transaction stands as a factual reduction in exposure at current market levels.

CEO West sells 62,447 shares (~$5.0M) across 5 transactions; retains 6.88M shares in $9.7B firm.

Alfred P West Jr. (CEO) executed 5 separate sales totaling 62,447 shares for $5,003,141.58 at a blended average of $80.12, reducing holdings by 0.9% to 6,875,783 shares. The sales occurred at prices within the 52-week range ($66.45–$93.80), near recent levels, while the stock has declined 3.8% over 30 days and 4.6% over 90 days from the transaction dates. His cross-ticker track record shows a 40.00% well-timed rate across 20 prior sells (average 90d return: -1.0%), but at SEI specifically, 0 of 5 prior sales preceded gains, with the most recent sale (December 2025) followed by a +2.2% 90-day return. The company remains fundamentally solid: $578.5M quarterly revenue, $164.2M net income, +8.1% annual growth, and an 11.62 P/E, supporting the modest sale magnitude within the context of retained substantial holdings.

CEO Ryan Hicke sells 80,000 shares for $6,989,060.42 in 3 transactions on 2026-01-29, reducing stake by 28.9%

Hicke Ryan, CEO of SEI Investments, executed 3 separate sales totaling 80,000 shares (80.0K shares) for $6,989,060.42 ($7.0M) at a blended average price of $87.36, reducing his holdings from 277,163 shares to 197,163 shares—a 28.9% reduction in stake. The transaction occurred near SEIC's 52-week high of $93.80 (current price $88.69 is -5.4% from that peak), within a period of strong momentum (+6.8% over 30 days, +8.6% over 90 days). His prior same-ticker sells have shown mixed timing: the most recent sale on 2025-08-19 suffered a -10.8% decline at 90 days, but an earlier sale on 2024-10-25 preceded a +12.5% gain. Across his cross-ticker history, his prior 3 sells averaged +2.5% return over 90 days with a 33.33% well-timed rate (meaning sells that preceded declines), indicating his open-market sell decisions have not consistently preceded downturns. The underlying company fundamentals remain solid: $578.5M quarterly revenue, $164.2M net income, +10.7% annual revenue growth, and a 15.53 P/E ratio.

Executive Chairman West sold 24,770 shares of SEIC at $80.87; remains largest shareholder with 6.94M shares post-sale.

West Alfred P Jr, as Executive Chairman, sold 24.8K shares at $80.87, reducing his holding by only -0.4% to 6.94M shares—he remains a dominant shareholder. At the time of sale, the stock was -13.5% from its 52-week high and down -1.6% over the prior month. His cross-ticker track record shows 20 prior sells with an average 90d return of -0.7% and a 40% well-timed rate, indicating modest but above-random predictive power. However, his same-ticker history at SEIC across 5 prior trades reveals a very different picture: all prior sells resulted in positive subsequent returns (ranging from +4.4% to +7.4% over 90 days), meaning 0 of 5 were well-timed by the sell-timing standard (well-timed sells should precede declines). The current sale, executed at a price -13.5% below the 52-week high, occurs after the stock has already declined materially from its peak. Fundamentally, SEIC reported $578.5M in latest-quarter revenue, +10.7% year-over-year growth, net income of $164.2M, and a P/E of 14.20 across a $9.9B market cap—metrics consistent with a mature, profitable business. The sale is modest in scale relative to his total holdings, and without a documented trading plan or scheduled disposition, represents a discretionary open-market transaction.

EVP Peterson sold 25,000 shares of SEIC at $84.21, reducing holdings 64.9%; stock now -12.3% from 52-week high.

Peterson Michael, Executive Vice President of SEI Investments Co., sold 25,000 shares (25.0K shares) at $84.21 on 2025-11-12, reducing his holdings from 38,500 shares (38.5K shares) to 13,500 shares (13.5K shares)—a substantial 64.9% reduction. The stock has declined -12.3% from its 52-week high of $93.80 and is trading below the transaction price. His cross-ticker track record shows a 28.57% well-timed rate across 7 prior sells, with positive 90-day average returns of 2.7%; however, his same-ticker history at SEIC tells a different story—only 1 of 5 prior sells at this ticker were well-timed at the 90-day mark, and recent trades in August 2025 and May 2025 both resulted in negative 90-day returns (-7.0% and -5.1% respectively). The magnitude of this reduction and the recent pattern of poorly-timed exits at SEIC merit observation, though the company's fundamentals remain sound (revenue growth of 10.7%, P/E of 14.41, and $164.2M net income).

CEO Ryan Hicke sold 35.0K shares of SEIC at $88.30 for $3.1M, reducing holdings by 17.0% to 171.3K shares

Ryan Hicke, CEO of SEI Investments, sold 35,000 shares at $88.30 on 2025-08-19, reducing his holdings by 17.0% from 206.3K to 171.3K shares. The stock currently trades at $88.40, only -5.8% from its 52-week high of $93.80, while the company reports strong fundamentals with $559.6M quarterly revenue, $227.1M net income, and 10.7% annual revenue growth at a reasonable P/E of 15.84. His cross-ticker track record shows 2 prior sells with a 90d well-timed rate of 0.00%, and his same-ticker history at SEIC reveals 2 prior sales posted positive 90d returns (+5.6% and +12.5%), indicating neither sale preceded a decline. This transaction occurred at a price near the 52-week high, and the modest recent decline of -2.8% over 30 days offers no signal that the insider moved ahead of material deterioration.

Peterson (EVP) sold 7,089 shares of SEIC at $88.55, reducing holdings 34.4% to 13.5K shares; stock now -6.7% from 52-week high.

Michael Peterson, Executive Vice President, sold 7,089 shares for $627,730.95, reducing his holdings by 34.4% from 20,589 shares to 13.5K shares. The sale occurred at $88.55 per share when the stock was already -6.7% from its 52-week high of $93.80, and the stock has declined a further -5.5% over the past 30 days. His prior sales at SEIC show mixed timing outcomes: of 4 measurable prior sales at this ticker, 0 were well-timed at the 90-day mark, with returns ranging from -9.3% to +13.1% at the 90-day horizon. The sale size and percentage reduction represent a meaningful portfolio action by an EVP at a company with $559.6M quarterly revenue and a 15.68 P/E.

Executive Chairman West sells 141,126 shares over 2 days for $12.0M at $85.08 avg; retains 6.94M shares.

Alfred P West Jr sold 141,126 shares across 3 separate transactions (75,000 shares at $85.78 on 2025-05-28; 64,498 shares at $84.26 and 1,628 shares at $85.21 on 2025-05-29) for a combined $12,006,823.36, resulting in a blended average price of $85.08. This represents a -2.0% reduction of his pre-transaction holdings of 7,078,708 shares, leaving him with 6,937,582 shares post-sale. His prior trades at SEIC show negative 30-day returns across all 5 measurable sales (ranging from -1.6% to -4.8%), though 90-day outcomes remain immeasurable for those earlier March 2025 trades. Against his cross-ticker track record of 20 prior sells with a 57.14% well-timed rate and -1.9% average 30-day return, this sale occurs at prices near the 52-week high of $86.58 (within -1.5%) and during a period of recent strength (+8.9% over 30 days). The company's fundamentals remain solid with $551.3M quarterly revenue, +10.7% annual growth, and a P/E of 17.65.

The company continues to demonstrate solid operational momentum with 10.7% annual revenue growth and a P/E of 17.68, suggesting he sold into a strong valuation environment rather than during weakness.
