CEO Jack Huang buys 216,300 shares for $4.6M across 6 days (blended $21.13) under 10b5-1 plan; stock now -72.5% from 52-week high.

Jack Jiajia Huang, CEO of 51Talk Online Education Group (COE), executed 6 purchases totaling 216,300 shares for $4,570,569.60 at a blended average price of $21.13 between June 8–15, 2026, as disclosed in a Form 4 filed on June 8, 2026. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-25, meaning the purchases were scheduled rather than discretionary. The stock currently trades at $15.42, down 72.5% from its 52-week high of $56.13, and down 43.9% over the preceding 30 days. Huang's post-transaction holdings stand at 27,032,940 shares, an increase of 0.8% from his pre-transaction position. While the CEO's cross-ticker track record shows 20 prior buys with an average 30-day return of −23.3%, the structured nature of the 10b5-1 plan removes discretionary timing from this particular filing and limits inference to the pre-arranged schedule rather than market signal.

CEO Jack Jiajia Huang purchased 165,240 shares for $4,128,862.20 across 6 transactions; stock down -60.9% from 52-week high

Jack Jiajia Huang, Chief Executive Officer, executed 6 separate purchases totaling 165,240 shares for $4,128,862.20 from 2026-05-29 through 2026-06-05, with a blended average price of $24.99. The current price is $21.97, representing a -60.9% decline from the 52-week high of $56.13. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-25, meaning it is scheduled rather than discretionary. Huang's same-ticker history at COE shows 5 prior buys with 30-day and 90-day returns all in the -16.1% to -18.5% range, and his cross-ticker track record across 20 prior buys reflects an average 90-day return of -17.4% with a 0.00% win rate over 90 days.

CEO Jack Jiajia Huang purchased 183,000 shares (183.0K shares) for $4,847,652.60 ($4.8M) across 4 transactions via pre-arranged 10b5-1 plan.

Jack Jiajia Huang, Chief Executive Officer of 51Talk Online Education Group (COE), executed 4 separate purchases totaling 183,000 shares for $4,847,652.60 at an average price of $26.49 between May 22 and May 28, 2026. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-25, meaning the purchases were scheduled rather than discretionary. The current stock price of $25.75 is -54.1% from the 52-week high of $56.13, and the stock has declined -8.0% over the past 30 days. Notably, Huang's same-ticker history shows 5 prior purchases at COE all occurring May 15–21, 2026, with each resulting in negative 30-day and 90-day returns ranging from -2.2% to -8.0%, indicating a pattern of purchases during a prolonged downtrend with no reversal to gains in the measured windows. The scheduled nature of these purchases and the continuation of a buying pattern across a period of persistent stock decline preclude timing-based characterization, but the sustained negative post-purchase returns across all recent same-ticker transactions merit monitoring.

COE CEO Jack Jiajia Huang purchased 155,220 shares for $4,185,772.20 across 5 trades via pre-arranged 10b5-1 plan

Jack Jiajia Huang, CEO of 51Talk Online Education Group, executed 5 separate purchases totaling 155,220 shares for $4,185,772.20 between May 15–21, 2026, at prices ranging from $26.34 to $28.00 with a blended average of $26.97. This activity was part of a pre-arranged 10b5-1 trading plan adopted on 2025-12-25, meaning the purchases were scheduled rather than discretionary. The current stock price of $26.40 is 53.0% below the 52-week high of $56.13, though it has appreciated 13.7% over the prior 30 days. The CEO's holdings increased from 26.31M to 26.47M shares, representing a 0.6% addition to his existing position.

CEO Huang Jack Jiajia purchased 84,180 shares for $2,140,178.40 across 4 trades (May 11–14) via pre-arranged 10b5-1 plan

CEO Huang Jack Jiajia executed 4 separate purchases totaling 84,180 shares for $2,140,178.40 under a 10b5-1 trading plan adopted on 2025-12-25, meaning these were scheduled transactions rather than discretionary decisions. The purchases occurred at prices ranging from $25.22 to $26.42, with a blended average of $25.42, while the stock currently trades at $27.50. His post-transaction holdings of 26,313,180 shares represent a 0.3% increase from his pre-transaction position. With recent 30-day and 90-day price appreciation of +14.4% and +4.7% respectively, the stock has recovered significantly from its 52-week low of $15.32, though it remains -51.0% below its 52-week high. Given the pre-arranged nature of this acquisition under Rule 10b5-1, no timing-based inference regarding conviction can be drawn.

CEO Huang Jack Jiajia acquired 119,400 shares across three open-market purchases as stock trades 54% below 52-week high.

CEO Huang Jack Jiajia acquired more than 119,000 shares in three consecutive trading sessions, continuing an aggressive buying pattern that has defined his activity over the past three years—30 open-market purchases with zero sales. The purchases occurred as the stock retreated significantly from its 52-week high, presenting a lower entry point into a company with a substantial market value. His prior buying history at this ticker shows mixed results: of his five previous purchases with measurable outcomes, the stock subsequently rose after two of them (well-timed buys) but fell after three of them (poorly-timed entries). This current buying spree mirrors that mixed pattern—he's buying into weakness, but his track record at this specific company suggests that timing has been inconsistent. The absence of any sales in his 36-month filing history underscores a buy-and-hold conviction, yet the recent downturn from the 52-week high and his mixed prior outcomes at this ticker mean this accumulation carries real execution risk, even for the company's CEO.

CEO Huang purchases 447K shares over 8 days totaling $12.2M in stock trading well below recent highs.

CEO Huang Jiajia executed a substantial open-market accumulation of roughly 447,000 shares across eight trading days in late April and early May, committing over $12 million to the purchase. This is a significant commitment by the company's top executive, though it occurs in a context that warrants scrutiny: COE's stock has declined substantially from its highs and trades well below that level, making this a purchase into material weakness. Huang's own track record at this ticker shows mixed results—of his five prior purchases in COE stock, two were followed by gains but three were followed by declines, suggesting his timing at this specific company has been inconsistent despite a stronger cross-company buying record overall. The CEO's substantial allocation and the fact that he has never sold shares—only accumulated across 19 prior open-market purchases and one stock-compensation transaction—suggests a long-term commitment to the company. However, the repeated purchasing at deteriorating prices during a broader downturn, combined with his uneven historical timing in COE specifically, indicates this should be monitored to see whether the stock rebounds or whether the CEO is catching a falling knife.

CEO Jack Jiajia Huang buys 146,400 shares in 4 transactions (Apr 20–23) for $3,644,185.20 at blended average $24.89

CEO Jack Jiajia Huang executed 4 separate open-market purchases totaling 146,400 shares for $3,644,185.20 between April 20–23, 2026, at prices ranging from $23.59 to $25.71, representing a 0.6% increase to his 25.66M-share post-transaction position. The timing of these purchases is notable: they occurred during a period when the stock was down 52.6% from its 52-week high of $55.56 yet up 39.4% over the prior 30 days, suggesting the CEO acted as the price stabilized after a sharp rally. His cross-ticker track record shows 17 prior buys with an average 30-day return of +36.6%, though same-ticker prior outcomes at COE remain immeasurable as of this filing. The scale of capital deployed ($3.6M) and the concentration of purchases within a four-day window warrant attention to whether this reflects a material conviction signal or routine portfolio activity.

CEO Huang Jack Jiajia purchased 384,960 shares ($9.6M) across 5 transactions at $22.22–$25.79 on Apr 13–17, 2026.

CEO Huang Jack Jiajia executed 5 separate purchases totaling 384,960 shares for $9,557,599.20 at a blended average price of $24.83 over four trading days (April 13–17, 2026), adding 1.5% to his existing stake of 25.13M shares. The timing is notable: purchases occurred while the stock traded near its 52-week midpoint ($22.22–$25.79), following a 39.6% surge over 30 days but amid an 8.0% decline over 90 days and well below the 52-week high of $55.56. This volume of insider accumulation in a company with $8.1B market cap by the CEO warrants attention as a data point in assessing how leadership views current valuation relative to the stock's recent volatility. Prior trades at this ticker remain too recent to measure outcome (all five prior COE purchases lack 90-day return data), and his cross-ticker buy track record shows 13 prior purchases but no historical 90-day outcome pattern has yet emerged.

CEO Huang Jack Jiajia bought 1,740,240 shares (1.74M) for $35,332,456.80 across 10 transactions from 2026-03-26 to 2026-04-09 at blended average price $20.30.

Over a two-week window spanning March 26 to April 9, 2026, CEO Huang Jack Jiajia executed 10 separate open-market purchases totaling 1,740,240 shares (1.74M shares) for $35,332,456.80 ($35.3M). This aggressive accumulation represents a 7.4% increase to his holdings (from 23.39M to 25.13M shares). The timing coincides with the stock at $13.71–$55.56 52-week range; current price at $22.30 is 59.9% below the 52-week high, though 30-day momentum shows +16.5% gains. The CEO's purchase prices ranged from $18.35 to $22.96, with multiple tranches concentrated in the $19–$22 band. This multi-tranche, concentrated accumulation warrants examination of concurrent company developments or market conditions that may have prompted a significant capital deployment by the top executive.
