COO Jonathan Lum sold 5,000 shares of CACC for $2,875,000.00 on 2026-05-29 via 10b5-1 plan

Jonathan Lum, Chief Operating Officer, sold 5,000 shares at $575.00 per share on 2026-05-29 under a pre-arranged 10b5-1 trading plan, reducing his holdings from 36,608 shares to 31,608 shares. The transaction is scheduled rather than discretionary, limiting inference about his real-time market assessment. Examining his prior trades at CACC specifically, his five prior sales showed mixed post-trade performance: the 2026-04-20 sale saw +5.0% over 90 days and the 2026-05-06 sale saw +2.1%, while three sales on 2025-08-25 each recorded declines of -16.0%, -16.2%, and -16.4% over 90 days. His cross-ticker track record across 14 prior sales shows an average 90-day return of -13.4%, but this broader pattern does not necessarily predict outcomes at CACC. The company trades at a P/E of 12.50 with $580.0M in latest quarterly revenue and 7.2% annual growth.

COO Jonathan Lum exercises and immediately sells 4,000 shares same-day, offsetting gains in profitable company with strong revenue growth.

Jonathan Lum, the company's Chief Operating Officer, exercised stock options for 4,000 shares and sold the entire position the same day at a higher price, netting a gain. This is notable because Lum has never purchased shares on the open market in the prior three-year window—his entire trading history consists of 14 open-market sales and 6 stock-compensation transactions. The immediate exercise-and-sell structure is consistent with his established pattern of liquidating equity compensation. The company itself remains financially sound, with profitable operations and growing revenue, trading modestly below its recent highs. While Lum's prior five sales at this ticker all proved well-timed (the stock declined after each sale), that consistent track record of exits predates this transaction—the most recent prior sale was just weeks earlier. The current trade is a mechanical equity-comp conversion rather than a discretionary open-market position, making it a routine liquidity event rather than a signal of insider conviction or concern.

COO Jonathan Lum sells 3,000 CACC shares at $535.00 on 2026-04-20; stock up 20.2% in 30 days; his prior 5 CACC sales all matched with 90d declines (100% timing).

Jonathan Lum, Chief Operating Officer of Credit Acceptance Corp, sold 3,000 shares at $535.00 on 2026-04-20, reducing his holdings by 8.7% to 31.6K shares. This sale warrants attention given the insider's remarkable track record at this ticker: his prior 5 trades at CACC were all sells executed on 2025-08-25, each followed by 90-day declines ranging from -15.8% to -17.4%, establishing a 100% well-timed rate. The current stock has risen 20.2% in the past 30 days and trades at -3.1% from its 52-week high of $543.74, positioning this sale near recent peaks. Cross-ticker, Lum's broader track record shows 12 prior sells with a 100.00% 90-day well-timed rate and avg 90d return of -16.2%, suggesting consistent pattern recognition in his exit decisions. Whether this sale signals anticipated weakness or reflects portfolio rebalancing at current valuations remains to be observed.

COO Jonathan Lum sold 6,000 shares of CACC for $3.1M across 10 transactions; prior same-ticker sales both well-timed (90d declines).

Jonathan Lum, Chief Operating Officer of Credit Acceptance Corp, executed 10 separate sales totaling 6,000 shares for $3,075,683.85 on 2025-08-25, reducing his holdings from 37.5K shares to 31.5K shares (-16.0%). The 10 transactions ranged from $508.69 to $518.39 per share, with a blended average of $512.61. Current price stands at $510.27, near the blended sale price. His prior two trades at CACC (both in March 2024) demonstrated strong 90-day timing, with 100% of same-ticker prior sells well-timed (both followed by declines of -13.6% and -13.8% at the 90-day mark). Cross-ticker, his track record shows a 100% well-timed sell rate across 2 prior transactions, though with mixed intermediate returns (30d +0.8%, 90d -13.7%). The company's fundamentals show healthy growth—annual revenue growth of +13.7%, P/E of 13.51, and the latest quarter posted $87.4M net income on $583.8M revenue—but the sale pattern mirrors his established behavior at this ticker and supports the historically consistent 90-day outcome pattern rather than signaling fundamental deterioration.
