 Insider of the Week: 51Talk CEO Buys $9.5M in Shares CEO of 51Talk Online Education Group (COE) Huang Jack Jiajia purchased 384,960 shares at $24.83 — that's $9.56 million of personal funds invested in the company. Not options, not bonuses, but a direct open market purchase. Why this is a strong signal: • CEO increased his stake by +1% — modest in percentage terms, but huge in amount • Purchase price of $24.83 is a benchmark for traders, below which the CEO considers shares undervalued • The company operates in EdTech (English for Asia) — a niche recovering from the post-COVID slump Other significant insider purchases on April 22, 2026: • Kailera Therapeutics (KLRA) — Rtw Investments fund bought 500,000 shares for $8M at $16.00 (+5% stake) • H2O America (HTO) — Atlas Holdings Ltd bought $3M at $59.06 • Nuburu (BURU) — Co-CEO bought 4.3 million shares at $0.35 (but the deal is from December 2025) My analysis: COE is the most interesting case. The CEO invested nearly $10 million of his own money. At the current price of ~$14.63, this is 40% below his purchase price — potential for a rebound. Low liquidity (0.14% turnover) adds risk, but an insider purchase of this magnitude outweighs it. For investors and traders: watch COE this week. If the price starts moving toward $24 — confirmation of the signal.
