Guy Chiarello, Chief Operating Officer, executed 2 separate sales totaling 45,000 shares for $10,599,607.50 on 2025-02-20, reducing his position by 16.5% to 227.7K shares. The transactions at $235.34 and $236.19 occurred near the 52-week high of $236.34 (only -0.8% below peak), and the stock has risen 12.2% over the prior 30 days. His prior 5 trades at Fiserv show consistently positive 90-day returns (ranging 17.3% to 29.2%), with none achieving negative returns that would indicate well-timed sales relative to subsequent declines. The current execution coincides with elevated valuations (P/E 42.09) and the stock near its 52-week peak, though the timing outcome versus subsequent price action remains to be determined.

FISERV COO Guy Chiarello sold 24,000 shares at $164.97 on 2024-08-15 for $3,959,280.00

Guy Chiarello, Chief Operating Officer of FISERV INC, sold 24,000 shares at $164.97 in an open-market transaction, reducing his post-transaction holdings to 163,699 shares (a -12.8% reduction from prior holdings). The stock is now trading at $165.72, essentially at its 52-week high, having risen 8.5% over 90 days and 5.5% over 30 days. Chiarello's prior five trades at FISERV have all been sells, with the most recent three (all in June and July 2024) showing strong post-trade performance: his June sales yielded +6.5% and +6.0% within 30 days, and his July sales returned +5.8% and +6.0%. His only measured 90-day outcome at FISERV (from the May 15 sale) was +4.9%, and across his broader cross-ticker history, his sell-timing success rate stands at 26.67% well-timed (meaning the stock fell after the sale). The recent sales cluster during a period of sustained stock strength, combined with an unbroken pattern of sales at this ticker, warrant investor attention given the company's strong fundamentals (P/E 27.67, +7.6% annual revenue growth, $95.4B market cap).

Guy Chiarello, COO of Fiserv, executed 2 separate sales totaling 24,000 shares for $3,716,563.58 on 2024-07-15, reducing his holdings by 12.8% from 187.7K to 163.7K shares. The blended average sale price of $154.86 was just 1.5% below the current price of $157.14 and well above the 52-week low of $109.61, placing the transaction near the upper end of the 52-week range. His cross-ticker track record shows a 90-day well-timed rate of 33.33% across 20 prior sells (meaning only one-third of prior sales have been followed by stock declines), while at Fiserv specifically, 0 of 1 measurable prior sales demonstrated well-timed execution at the 90-day mark. The transaction represents normal portfolio adjustment rather than an obvious signal of conviction or concern given the stock's recent positive 30-day (+5.5%) and 90-day (+6.8%) performance.
