Significance 6

Director Stephen Schillig buys 80 shares of CSBB at $68.48, raising stakes by over 40% amid recent recovery.

Director Stephen Schillig made an open-market purchase of CSB Bancorp shares at a price above current levels, meaningfully increasing his ownership stake by more than 40 percent. The purchase comes as the stock has recovered sharply from its recent lows and is now trading just shy of its 52-week high, a timing that's notably different from the typical insider-buying pattern—most board members buy during selloffs, not during rallies. The company's financial fundamentals are solid: it remains profitable with reasonable valuation metrics, suggesting Schillig is buying into a relatively healthy business rather than catching a falling knife. The combination of a director's conviction purchase with a large percentage increase in holdings, paired with strong recent momentum and stable profitability, indicates Schillig sees value at current levels—though the near-peak pricing demands scrutiny about whether the recent rally has fully run.

Director Kirkbride buys 9 CSBB shares at $62.00, matching 52-week high; stock +8.8% in 30 days, +12.7% in 90 days.

Director Cheryl M Kirkbride purchased 9 shares of CSB Bancorp at $62.00 on 2026-03-24, bringing her total holdings to 1,374 shares—a modest 0.7% increase. The transaction occurred at the current 52-week high, with the stock having appreciated 8.8% over the prior 30 days and 12.7% over 90 days, suggesting the purchase came after recent upward momentum rather than at a depressed level. Her SAME-TICKER HISTORY at CSBB shows 3 of 5 prior buys were well-timed at the 90-day mark, with mixed near-term outcomes (30-day returns ranging from -7.1% to +0.1%), though longer-term results leaned positive. The company trades at a P/E of 9.49 with a market cap of $162,874,930.00. The small share count and minimal portfolio movement limit the apparent conviction signal from this transaction.

At the current price of $57.00, the stock is trading near its 52-week high of $58.50 and up 6.3% over the prior 30 days and 16.3% over 90 days, reflecting recent upward momentum. The company's P/E of 10.86 and net income of $4,151,000.00 provide a small-cap valuation context.

The current price of $57.52 places the stock near its 52-week high of $58.50, and recent momentum is strong (30-day: +7.5%, 90-day: +16.8%). The company's valuation remains conservative at a P/E of 10.96 on net income of $4,151,000.00, with market cap of $151,233,079.52. The consistency of Steiner's timing success across all five prior CSBB buys—a 100% well-timed rate—alongside his cross-ticker track record showing a 95.00% 90-day win rate and an average 90-day return of +6.1%, suggests disciplined execution at this security.

Director Kirkbride bought 125 shares in 2 transactions at $51.75–$53.00; flat post-purchase vs 52-week high, poor prior timing record

Cheryl M Kirkbride, Director, purchased 125 shares across 2 separate transactions on 2025-10-30 at a blended average price of $52.50, increasing holdings from 2,130 to 2,255 shares. The current price of $50.00 is 4.9% below the 52-week high of $52.60, placing the purchase near recent peaks. Kirkbride's prior trade history at CSBB is unfavorable: of 5 prior trades, only 1 of 4 measurable CSBB buys achieved a positive 90-day return (+7.4% on the 2024-01-26 trade), while the other three posted 90-day declines ranging from -1.3% to -2.8%. Her cross-ticker track record shows an average 90-day return of -0.3% across 7 prior buys with a 16.67% win rate. The combination of purchases near the 52-week high and a consistent pattern of underperformance in both this ticker and across her broader trading history presents a cautionary signal for assessing the fundamental conviction behind this accumulation.

Schillig's prior buy at this ticker on 2025-07-31 showed minimal 30-day movement (+0.2%), while his cross-ticker track record across 3 prior buys reflects mixed timing with a 50.00% 90-day win rate and an average 90-day return of +1.9%.
