November 2022: the largest joint operation in SFC and ICAC history — 190 officers, 50 premises searched — against a pump-and-dump syndicate that ran like a business: "investment teacher" chatrooms, brokerage insiders, nominee accounts, and retail investors as exit liquidity. The alleged illegal gains: HK$191 million.

1. The industrial supply chain

Pump-and-dump supply chain Syndicate → insider accounts → influencer chatrooms → retail victims → laundered exits. Syndicate accumulates the float Inside men brokerage ROs / chairmen Influencer rooms "teachers" + fake students Retail victims buy the top Stage 1 — accumulate: nominee accounts quietly buy the illiquid small-cap float Stage 2 — pump: chatroom "teachers" hype the stock; fake students post profits Stage 3 — dump: syndicate sells into retail demand; proceeds laundered through insider accounts
Fig: the industrialised loop — insiders made the pump look legitimate; social media made it feel safe.

2. Why retail investors fall for it

The scam doesn't steal your money — it makes you press the buy button yourself. The "teacher" calls trades; the "fellow students" (mostly the syndicate's own accounts) post wins; FOMO does the rest. By the time the victim owns the shares, the syndicate is already out.

3. Why the enforcement is hard

RegSir's take

The structural finding is the "inside man" problem: the regime's first line — self-reporting by intermediaries — fails when the intermediary is the fraud. Controls assume compliance staff report anomalies; these cases had ROs running the anomaly. The answer isn't more rules for honest firms — it's independent anomaly detection (transaction surveillance that doesn't rely on the desk flagging itself) and rotation/removal incentives that make insider collusion expensive. Regulators also need to price in that Telegram-era manipulation is telecom fraud wearing a market face — coordination, not just statute, is the tool.
