Historically, medium-priority insider buys have outperformed the S&P 500 by a median ~1% over the 30 days after filing — the edge is concentrated in that first month (n ≈ 7,520, 2022-2026). Past results don't predict the future. How we measure this ↗

Significance 3/10

BLIN President/CEO Kahn purchases 10,000 shares at $0.93 (current $0.99); three buys in five days; stock -53.7% from 52-week high.

Roger E. Kahn purchased 10,000 shares at $0.93 on 2026-03-10, following two prior buys on 2026-02-19, 2026-02-18, and 2026-02-17—a rapid clustering of acquisitions within days. His holdings grew to 1.77M shares post-transaction (+0.6% vs prior). The stock trades 53.7% below its 52-week high of $2.14, having recovered +32.0% over 30 days, but across his prior five trades at BLIN, zero of the measurable outcomes showed positive 90-day performance (ranging from -0.7% to -31.5%). Fundamentally, the company posted quarterly revenue of $3.9M with a net loss of $-86.0K and negligible annual growth of +0.2%, alongside full-year unprofitability. The rapid sequence of small purchases amid weak fundamentals and a poor track record of post-purchase gains at this ticker does not demonstrate conviction aligned with stock-price recovery.

Significance 3/10

Director Ketslakh Michael bought 6,959 shares at $0.85 across 2 transactions (2026-03-02 & 03) totaling $5,915.15 at depressed valuation; stock down 57.9% from 52-week high.

Michael Ketslakh (Director) executed 2 separate purchases totaling 6,959 shares for $5,915.15 at an average price of $0.85, adding 1.4% to his 486.9K share position. The purchases occurred at $0.70–$2.14 52-week range context, with the stock currently at $0.90, representing a 57.9% decline from the 52-week high. Bridgeline Digital has negative trailing net income of $-86.0K and minimal revenue growth of 0.2% year-over-year on a $3.9M quarterly revenue base, reflecting fundamental weakness. Notably, Ketslakh has completed 4 prior purchases at BLIN in February 2026 (within the last week), signaling repeated accumulation at a distressed price level, though his broader cross-ticker buy track record shows 0.00% 90-day win rate and -2.6% average 90-day return.

Significance 3/10

Director Ketslakh Michael purchased 13,041 shares at $0.85 across 2 transactions at BLIN; stock down -59.8% from 52-week high

Director Michael Ketslakh purchased 13,041 shares in 2 separate transactions totaling $11,084.85 at a blended average price of $0.85, increasing his holdings to 486,883 shares. The purchases occur in a weakened context: the stock trades at $0.86, down -59.8% from its 52-week high of $2.14, and the company reported net income of -$86,000 on revenue of $3,913,000 for the latest quarter with annual revenue growth of only +0.2%. Ketslakh's prior buy at this ticker on 2025-03-26 returned +9.9% in 30 days but -2.6% in 90 days, indicating these discretionary buys have not consistently captured durable value. The 30-day price move of +4.2% suggests modest near-term momentum following his purchase, but the company's profitability challenges and weak full-year fiscal performance remain structural headwinds.

Significance 3/10

Director Ketslakh Michael buys 1,353 shares of BLIN at $0.85; stock down 60.3% from 52-week high of $2.14.

Director Ketslakh Michael purchased 1,353 shares at $0.85 on 2026-02-19, increasing his holdings from 472,489 to 473,842 shares. The purchase represents a small 0.3% addition to his existing position at a price that is 60.3% below the 52-week high of $2.14, though modestly above the 52-week low of $0.70. Critically, the company is unprofitable, posting net income of $-86.0K in the latest quarter against quarterly revenue of $3.9M, with annual revenue growth of only +0.2% year-over-year and a market cap of just $10.7M. The insider's prior buy at BLIN on 2025-03-26 generated a positive 30d return (+9.9%) but delivered a negative 90d return (-2.6%), and his cross-ticker track record shows 0 of 1 prior buys were well-timed at the 90-day mark, suggesting limited predictive success in his buy timing.

Significance 3/10

BLIN CEO Kahn bought 54,301 shares for $42,205.75 over 3 days (Feb 17-19, 2026) at $0.78 avg; holds 1.76M post-transaction.

Roger E. Kahn, President and CEO, executed 3 separate purchases totaling 54,301 shares for $42,205.75 between 2026-02-17 and 2026-02-19 at a blended average price of $0.78, raising his holdings to 1,763,736 shares. The current price of $0.90 is 57.9% below the 52-week high of $2.14, placing the stock in the lower end of its annual range. Kahn's prior 5 open-market buys at BLIN all registered negative 90-day returns, with 0 of 5 achieving positive returns post-purchase; his cross-ticker track record shows a 10% win rate over 20 prior buys, with a 90-day average return of -9.1%. Bridgeline Digital's fundamentals remain stressed: the latest quarter revenue was $3,913,000.00, net income was negative at $-86,000.00, and the company posted near-flat annual revenue growth of +0.2% while remaining unprofitable for the full fiscal year.

Significance 3/10

CEO Kahn buys 54,500 shares (54.5K) across 2 purchases for $77,010.00 (blended $1.41); stock down -7.5% in 30 days, -12.3% in 90 days.

President and CEO Roger E. Kahn executed 2 separate open-market purchases totaling 54,500 shares (54.5K shares) for $77,010.00 ($77.0K) on 2025-06-20 and 2025-08-26, expanding his holdings from 1,242,289 shares to 1.30M shares. However, his prior 5 trades at BLIN show a persistent pattern of poor timing: 0 of 5 prior buys delivered a positive 90-day return, with losses ranging from -1.3% to -13.6% over the 90-day window. Against this history, the current stock price of $1.36 sits -42.1% from the 52-week high, and the company reported negative net income of $-789,000.00 (quarterly) alongside -3.3% annual revenue decline. While the CEO's continued purchases suggest internal positioning, his prior trading pattern at this ticker and the company's unprofitable fundamentals provide limited conviction signals for external investors.

Significance 7/10

BLIN CEO Kahn purchases 100,100 shares for $155,591.00 across 7 transactions; now holds 1,156,387 shares.

CEO Roger E. Kahn executed 7 separate purchases totaling 100,100 shares for $155,591.00 at a blended average price of $1.55, raising his holdings from 1,056,287 to 1,156,387 shares (a +9.5% increase). This is a material accumulation by the company's chief executive. At his prior trades at BLIN, his timing has been mixed: two of four measurable outcomes showed positive 90-day returns (+26.4% and +29.4%), but two showed declines (-12.6% and -10.0%), indicating inconsistent predictive power at this ticker. The current stock price of $1.50 sits 36.2% below its 52-week high of $2.35, having declined 10.2% over the past 30 days. Fundamentally, the company is unprofitable (net income $-730,000.00 for the latest quarter, with annual revenue declining 3.3% year-over-year) and carries a market cap of $17,874,882.00. The purchase price ($1.55 blended) is above the current price ($1.50), meaning the executive is underwater on this filing already. Investors should monitor whether this accumulation represents confidence in a turnaround or simply reflects the CEO's continued commitment despite deteriorating operational performance.

Significance 5/10

CEO Roger E. Kahn buys 33,334 shares of BLIN at $1.52; stock down 37.4% from 52-week high, company unprofitable with -3.3% annual revenue decline.

CEO Roger E. Kahn purchased 33,334 shares at $1.52 on 2025-03-26, bringing his holdings to 1,056,287 shares, in a context where Bridgeline Digital trades at $1.47, down 37.4% from its 52-week high of $2.35. The company reported $3,791,000 quarterly revenue with a net loss of $-634,000, and full-year revenue declined 3.3% year-over-year. A cluster of two other insider buys within the past 14 days suggests coordinated executive confidence. However, Kahn's own cross-ticker track record shows a 90-day win rate of only 10.00% with a -13.1% average 90-day return, while his same-ticker history at BLIN reveals mixed timing: 2 of 5 prior buys were well-timed, including recent purchases on 2024-09-13 and 2024-08-20 that returned +26.4% and +29.4% respectively over 90 days. The transaction warrants attention given the company's unprofitable state and depressed valuation, though management's accumulation alongside peer purchases and positive same-ticker recent outcomes provide some counterweight to weak overall timing discipline.

Significance 6/10

Director Ketslakh Michael buys 394.7K shares at $1.52 as BLIN trades 37.4% below 52-week high; cluster pattern emerges with 2 other insider buys in past 14 days.

Director Michael Ketslakh purchased 394,736 shares at $1.52 on 2025-03-26, establishing an initial position worth approximately $600.0K. The transaction is noteworthy because it occurs within a cluster pattern: 2 other insiders also bought within the past 14 days, suggesting coordinated interest at current levels. The timing relative to price action is relevant—the stock trades at $1.47, down 37.4% from its 52-week high of $2.35, though up 8.9% over the past 30 days. The company's fundamentals are challenged: it reported negative net income of $-634.0K in the latest quarter, annual revenue of only $3.8M with year-over-year decline of 3.3%, and a market cap of $15.4M, indicating a distressed microcap. The cluster buy activity by multiple insiders into a deeply depressed small-cap with negative earnings invites scrutiny into the motivation for the accumulation.

@ $1.52
Significance 6/10

Director Joni Kahn bought 6,579 shares of BLIN at $1.52; cluster buying pattern observed among 3 insiders in 14 days

Joni Kahn, a Bridgeline Digital director, purchased 6,579 shares at $1.52 on 2025-03-26 representing an initial position worth $10,000.08. This purchase occurs within a cluster pattern where 2 other insiders also bought within the past 14 days, suggesting coordinated or independently motivated insider accumulation. The transaction coincides with a period of positive near-term momentum (+8.9% over 30 days, +2.8% over 90 days) despite the company's underlying operational challenges: negative net income of $-634,000.00 in the latest quarter, -3.3% annual revenue decline, and a market cap of only $15,350,635.23. The alignment of multiple insider purchases warrants examination of what visibility insiders may have regarding near-term performance or strategic developments.
