High conviction

This is a high-conviction signal — the insider is a first-time or occasional buyer, historically the strongest subset. Such buys have outperformed the S&P 500 by a median ~3% over the 30 days after the trade (n ≈ 3,001, 2024-2026). Past results don't predict the future. How we measure this ↗

Director Clark C Kellogg buys 3,000 shares of RLI at $50.90; holdings surge +199.7% as cluster buy pattern emerges among 3 other insiders in 14 days

Clark C Kellogg (Director) purchased 3,000 shares at $50.90, increasing his holdings from 1,502 to 4,502 shares (+199.7% increase). The transaction occurs within a cluster period in which 3 other insiders also bought RLI within the past 14 days, suggesting coordinated or independently aligned interest at current valuations. The stock is trading at $50.63, down 34.4% from its 52-week high of $77.24 and down 20.0% over the past 90 days, providing context for the timing relative to recent price weakness. With fundamentals showing net income of $54.9M on quarterly revenue of $423.9M and a P/E of 11.77, the company's valuation and recent price retreat appear to be the backdrop against which multiple directors are making purchases.

Director David B. Duclos bought 2,500 shares of RLI at $51.99 (May 2026); cluster of 2 other insider buys within 14 days.

Director Duclos purchased 2,500 shares at $51.99, increasing his holdings from 7,280 shares to 9,780 shares (+34.3%). This purchase occurs within a cluster pattern: 2 other insiders also bought within the past 14 days, suggesting aligned interest among multiple company insiders at this price level. Duclos's cross-ticker track record shows 1 prior buy with a 100% 90-day win rate and +2.2% average 90-day return; his prior RLI purchase on 2025-01-29 returned +2.2% over 90 days, demonstrating consistency in entry timing at this ticker. RLI trades at a P/E of 11.64 with quarterly revenue of $423.9M and net income of $54.9M, and the stock is currently -35.2% from its 52-week high of $77.24. The cluster activity and repeated insider participation warrant observation as a potential signal of management conviction near current valuations.

CEO Craig W Kliethermes buys 2,000 RLI shares at $52.00; stock down 33.3% from 52-week high of $77.24.

Craig W Kliethermes, Chief Executive Officer, purchased 2,000 shares at $52.00 on 2026-05-27, expanding his holdings from 149.0K shares to 151.0K shares. The purchase occurs with the stock trading 33.3% below its 52-week high of $77.24 and down 17.4% over 90 days. His prior two trades at RLI show mixed results: a January 2026 buy returned +6.0% in 30 days but -4.4% over 90 days, while a January 2025 buy returned +4.5% in 30 days but +5.4% over 90 days. The company's fundamentals remain solid with $423.9M in latest quarterly revenue, $54.9M net income, and a P/E of 11.98, though annual revenue growth of +6.3% and the stock's recent downward momentum warrant attention to near-term catalysts or headwinds.

Craig W Kliethermes, Chief Executive Officer of RLI Corp, purchased 5,000 shares at $52.00 on 2026-05-21, raising his holdings to 148,990 shares. The purchase occurred at a price -32.3% below the 52-week high of $77.24, following a 90-day decline of -15.2%, yet the stock is currently trading at $52.31—essentially flat to the transaction price. His prior trades at RLI show mixed timing: a January 2026 buy yielded a 90-day return of -4.4%, while a January 2025 buy returned +5.4% over 90 days. The company's fundamentals remain solid, with a P/E of 12.17, quarterly net income of $54.9M, and annual revenue growth of +6.3%. This transaction represents a modest increase (3.5%) to his existing position rather than a material accumulation.

RLI COO Jennifer Klobnak buys 2,000 shares at $53.42; stock now -32.5% from 52-week high, 1 of 3 prior RLI buys had positive 90d return.

Jennifer Klobnak, RLI's Chief Operating Officer, purchased 2,000 shares at $53.42 on 2026-05-19, increasing her holdings to 102,318 shares. The transaction occurs when RLI trades at $52.14, down 32.5% from its 52-week high of $77.24 and down 11.7% over the past 30 days. Klobnak's cross-ticker track record shows 3 prior buys with an average 90-day return of -4.0%, whereas her prior purchases at RLI specifically generated mixed results: one of her three prior RLI buys showed positive returns at the 90-day mark. The company's fundamentals remain solid—$423.9M in quarterly revenue, net income of $54.9M, and a P/E of 12.13—suggesting the stock's recent decline may reflect market volatility rather than fundamental deterioration. This insider purchase against a backdrop of short-term weakness and middling prior timing success warrants observation of whether RLI stabilizes in the coming weeks.

RLI CEO Kliethermes purchases 5,000 shares ($287.2K) at $57.45 as stock down 29.5% from 52-week high

Craig W. Kliethermes, Chief Executive Officer of RLI Corp, purchased 5,000 shares at $57.45 on 2026-01-23, raising his holdings to 144.0K shares from 139.0K shares. This buy occurs as RLI stock trades at $56.97, down 29.5% from its 52-week high of $80.82 and down 12.7% over the past 30 days, suggesting the CEO is willing to add to his position during a period of stock weakness. Kliethermes' prior buy at RLI exactly one year prior (2025-01-24) demonstrated positive 90-day returns (+5.4%), indicating a consistent pattern of open-market purchases at this ticker. RLI's fundamentals show revenue of $509.3M in the latest quarter with annual growth of 17.1% and net income of $124.6M, alongside a relatively modest P/E of 14.84, providing context for an insider investment during a down period.

RLI COO Jennifer L Klobnak bought 2,000 shares ($115,980) on 2026-01-23; stock down 29.5% from 52-week high.

Klobnak, RLI's Chief Operating Officer, purchased 2,000 shares at $57.99, expanding her holdings by 2.0% to 100,318 shares. The transaction occurred as RLI stock trades at $56.97, down 29.5% from its 52-week high of $80.82. Fundamentally, the company shows strength with $509.3M in quarterly revenue, $124.6M net income, 17.1% annual revenue growth, and a P/E of 14.84. However, Klobnak's historical track record provides limited conviction signal: across all tickers she has a 50% 90-day win rate on her 2 prior buys, and at RLI specifically, her prior 2 buys split outcomes (one up 4.3% at 90-day, one down 11.1%), making only 1 of 2 well-timed at the 90-day mark. The purchase occurs during a period of near-term weakness (down 12.7% in 30 days) but at a valuation discount to recent highs.

Director Duclos buys 2,000 shares of RLI at $72.50; cluster pattern with 4 other insiders in past 14 days

Duclos David B., a director of RLI Corp, purchased 2,000 shares at $72.50 on 2025-01-29, increasing his holdings by 38.4% from 5,214 to 7,214 shares. This $145,000.00 buy occurs within a broader cluster pattern: 4 other insiders also bought within the past 14 days. The stock is trading at $73.64, down 18.6% from its 52-week high of $90.44 and down 10.6% over the past 30 days, suggesting the purchase occurred in a period of price weakness. RLI trades at a P/E of 8.04 with a market cap of $3.4B, but faces headwinds: annual revenue contracted 11.0% and the latest quarter generated $470.0M in revenue with $95.0M in net income. The clustering of multiple insider purchases in a short timeframe, combined with recent price declines, provides a substantive signal for investor attention.
