Significance 5/10

Director BOULANGER NORMAND A sold 150,000 shares of SSNC at $85.85 for $12.9M, reducing holdings by -27.9%

Director BOULANGER NORMAND A executed a substantial sale of 150,000 shares at $85.85, representing -27.9% of pre-transaction holdings and generating $12.9M in proceeds. The sale occurred near the 52-week high of $90.20, within a modest 30-day positive window (+0.3%) but against a 90-day decline of -3.0%. His prior trades at SSNC show a timing pattern of 0 of 4 prior sells well-timed at the 90-day mark; historically his sales at this ticker yielded mixed returns (90-day outcomes ranged from +1.7% to +8.6%, meaning stock rallied after his exits). The company trades at a P/E of 24.56 with $1.6B in latest quarterly revenue and 6.9% annual growth, providing a reasonably valued backdrop. The magnitude of this sale—a material reduction of roughly one-quarter of holdings—warrants attention as a data point but absent FLAGS indicating constraint-free discretion, the timing and motivation remain ambiguous from price action alone.

Significance 5/10

Director Zamkow sells 18,900 shares (43.1% reduction) at $77.05–$77.60 totaling $1,463,365.53

Michael Jay Zamkow, a director at SS&C Technologies (SSNC), executed two separate sales on 2025-05-02, liquidating 18,900 shares for $1,463,365.53—a 43.1% reduction in his holdings to 24,976 shares post-transaction. The sales occurred at $77.05 and $77.60, near the stock's current price of $77.95, which is 12.5% below the 52-week high of $89.13. Reviewing his same-ticker trade history, one prior SSNC sale on 2024-09-20 showed a -2.2% 90-day return (well-timed), though a more recent sale on 2025-02-25 showed -5.4% at the 30-day mark (outcome at 90 days not yet measurable). His cross-ticker track record across all holdings shows 2 prior sells with a 100% well-timed rate at the 90-day mark (average 90d return -2.2%), suggesting a pattern of selling ahead of downturns, though the sample size is small. The current transaction does not appear connected to scheduled/announced trading plans, and the market valuation remains solid (P/E 23.55, market cap $19.2B), leaving the motivation for this moderately sized liquidation unclear from fundamentals alone.

Significance 6/10

Director MICHAEL JONATHAN E bought 2,700 shares of SSNC at $75.53 on 2025-05-01; holdings rise to 72,776 shares (+3.9%)

MICHAEL JONATHAN E, a director at SS&C Technologies Holdings Inc, purchased 2,700 shares at $75.53, increasing holdings from 70,076 to 72,776 shares—a 3.9% increase. The purchase occurred at a price 3.4% below the current price of $78.10 and significantly below the 52-week high of $89.13, suggesting the transaction took place in a period of relative weakness. With the company generating Revenue of $1,513,900,000.00 and Net income of $213,000,000.00 in the latest quarter, plus annual revenue growth of +6.9%, the director's modest accumulation occurs within a profitable, growing business context. The significance is moderate rather than critical: the transaction size represents a small percentage of a substantial holding, and without knowledge of whether this was discretionary or part of a scheduled trading plan, the directional signal remains limited.

Director ZAMKOW MICHAEL JAY sold 23,000 shares of SSNC at $88.39 on 2025-02-25 for $2,033,062.00, reducing holdings -37.8%.

Director ZAMKOW MICHAEL JAY executed a substantial open-market sale of 23,000 shares, worth $2,033,062.00, reducing his holdings by 37.8% to 37,876 shares. The sale occurred at $88.39, just 1.1% below the 52-week high of $89.13, while the stock has posted strong recent momentum: +8.9% over 30 days and +14.0% over 90 days. His cross-ticker track record shows a 100% well-timed rate on prior sells, with his one prior sale at SSNC (2024-09-20) demonstrating a -2.2% 90-day return, fitting the pattern of sells executed before subsequent declines. At current valuation (P/E 30.93, market cap $21.8B), this reduction suggests a rebalancing of his concentrated position rather than a forecast of fundamental deterioration.

Significance 6/10

SVP & General Counsel Jason Douglas sells 71,000 shares (91.7% of holdings) at $88.96, leaving 6,412 shares

White Jason Douglas, SVP & General Counsel, executed 2 separate sales totaling 71,000 shares for $6,316,351.70 at a blended average price of $88.96 on 2025-02-18, reducing his holdings from 77,412 to 6,412 shares—a 91.7% reduction. The transaction occurred near the 52-week high of $89.12 (current price at +0.0% from that peak), and the stock has rallied +13.5% over 30 days and +18.6% over 90 days. Against his cross-ticker track record of 2 prior sells with an average 30-day return of -0.2%, this large-scale exit is notable for its scope; his prior trades at SSNC (both on 2024-11-26) showed similar timing characteristics but lacked measurable 90-day outcomes. The near-complete liquidation of a senior legal executive's personal stake warrants attention to whether this reflects personal portfolio decisions or signals in the business outlook, particularly given the company's market cap of $22.1B and recent quarterly revenue of $1.5B.

Significance 4/10

CEO William C Stone sold 132,700 shares of SSNC at $76.85 on 2024-12-10, reducing stake to 31,837,926 shares.

William C Stone, Chairman of the Board & CEO of SS&C Technologies Holdings Inc, sold 132,700 shares at $76.85 for total value of $10,197,649.98. The sale reduced his holdings by -0.4% to 31,837,926 shares post-transaction, representing a modest divestiture. This marks his first prior sell in his cross-ticker track record and follows another sale at this same ticker on 2024-12-05. With the stock currently trading at $77.25 near its 52-week high of $77.36, the sale occurred just below current valuations. The company shows solid fundamentals with $1.5B in latest quarterly revenue, $164.4M net income, and a 27.11 P/E ratio, though the modest -0.4% position reduction offers limited interpretive signal on the CEO's conviction given he retains a substantial 31.84M share stake.

Significance 3/10

CEO William C Stone sells 247,300 shares of SSNC at $76.61 on 2024-12-05, retains 31.84M shares post-transaction.

CEO William C Stone sold 247,300 shares at $76.61 on 2024-12-05, representing a -0.8% reduction from his pre-transaction holdings of 32.09M shares. The sale occurred near the 52-week high of $77.36 and above the current price of $75.46, with the stock having appreciated 0.9% over the past 30 days and 2.8% over 90 days. Post-transaction, Stone retains 31.84M shares in a company with a $18.7B market cap, $1.5B quarterly revenue, and a P/E of 26.48, indicating he remains heavily concentrated in SSNC. The modest 0.8% reduction in holdings alongside substantial retained stakes suggests the sale was a limited proportion of his overall position.

Significance 7/10

SVP & General Counsel sold 69,000 shares (91.5% of holdings) for $5.3M at $77.07 on 2024-11-26

Jason Douglas, SVP & General Counsel at SS&C Technologies, executed two separate sales totaling 69,000 shares for $5,318,112.90 at $77.07 per share, reducing his holdings by 91.5% from 75,412 to 6,412 shares. The timing coincides with the stock near its 52-week high of $77.36 and following a 10.3% gain over the preceding 30 days. This substantial reduction in insider stake is material, as the seller disposed of the vast majority of his equity position in what was presumably his primary wealth-related asset in the company. Given the magnitude of the sell-off (69K shares out of 75.4K pre-transaction holdings), the transaction merits investor attention as a significant capital reallocation by a senior executive with governance responsibilities.

Significance 6/10

Director Zamkow sells 19,000 SSNC shares ($1.4M) at $75.97; retains 22,576 shares post-sale

Director Michael Jay Zamkow sold 19,000 shares at $75.97 on 2024-09-20, reducing his position by 45.7% from 41,576 to 22,576 shares and realizing $1,443,437.60 in proceeds. The transaction occurred near the stock's 52-week high of $76.46, with current price at $74.83, placing the sale at +1.1% versus 30-day average and well above the 90-day trend of +20.5%. SS&C operates at a P/E of 26.26 with recent quarterly revenue of $1,451,500,000.00 and net income of $190,300,000.00, supported by 4.2% annual revenue growth. The substantial reduction in Zamkow's holdings—nearly half the pre-transaction stake—represents a material change in his direct exposure to the company; the timing near recent highs and the magnitude of the reduction warrant investor attention to potential directional signals or portfolio rebalancing intent.

@ $75.38
Significance 5/10

Director Normand Boulanger sold 130.0K SSNC shares at $75.38 on 2024-09-16, retaining 333.6K shares; stock now at 52-week high.

Boulanger executed a substantial sale of 130,000 shares worth $9,798,828.00, reducing his position by 28.0% while still maintaining 333.6K shares. The transaction occurred at $75.38, and the stock currently trades at $75.53—at the upper bound of its 52-week range $48.71–$75.53. His prior three sales at SSNC (September 2023) each generated positive 90-day returns (+8.6%, +6.7%, +4.9%), indicating those earlier dispositions preceded stock appreciation rather than declines, with a 0.00% well-timed rate at this ticker. The current sale arrives after a 22.1% 90-day gain and +3.9% 30-day gain, suggesting disposition near recent strength. This represents a material reduction in insider holdings executed when the security is at peak valuation levels.
