1. Overview: Market Manipulation in China
Market manipulation (ๆ็ธฑ่ญๅธๅธๅ ด็ฝช) is the crime of using improper means to influence the price or volume of securities trading, disturbing market order, where the conduct is serious. It is among the largest-dollar and most severely penalized securities offenses in China. In 2025 the CSRC investigated 57 manipulation cases with an average amount involved of RMB 580 million.
With the spread of programmatic and algorithmic trading, new manipulation techniques have emerged. Traditional "market-making/position-building" schemes are giving way to spoofing, reverse trading, and quant-driven manipulation, creating new challenges for both enforcement and criminal characterization.
๐ Article 182, Criminal Law of the PRC (excerpt)
"Whoever manipulates the securities or futures market under any of the following circumstances, where the circumstances are serious, shall be sentenced to up to five years imprisonment or criminal detention, and shall also or solely be fined; where the circumstances are especially serious, shall be sentenced to five to ten years imprisonment and fined: (1) jointly or severally concentrating capital advantages, shareholding advantages or information advantages, or cooperating with others to continuously buy or sell; (2) colluding with others to trade securities/futures with each other at pre-agreed time, price and manner; (3) trading securities between accounts under one's own actual control, or buying and selling futures contracts with oneself as the counterparty; (4) frequently or massively placing and canceling orders without the intent to execute; (5) inducing investors to trade by using false or uncertain material information."
2. The Four Types of Manipulation
Continuous Trading Manipulation
Alone or in collusion, concentrating capital, shareholding or information advantages to continuously buy and sell, manipulating price or volume. Typical tactics: end-of-session mark-ups, intraday ramping, large orders to steer the market.
Matched (Collusive) Trading
Colluding with others to trade with each other at pre-arranged times, prices and manners, creating the illusion of active trading. Typical feature: counterparties with synchronized execution and matching prices.
Wash Trading
Trading between accounts under one's own control โ buying and selling to oneself โ to fabricate volume. Common in "tractor account" schemes where one controller operates many accounts to trade against each other.
Information-Based Manipulation
Using false or uncertain material information to induce investors to trade, or "pump and dump" (buy first, recommend, then sell). Newer variants exploit social-media rumors and "black-mouth" accounts.

4. Core Defense Strategies
Prove the trades followed a legitimate investment strategy or quant model, not a manipulative purpose. Quantitative and algorithmic strategies have inherent trading characteristics that require expert trade-data analysis.
Show the trading lacked a causal link to the price movement. Securities prices are affected by multiple factors โ argue the movement came from market forces, not the alleged manipulation.
Challenge the finding of actual control over accounts. Where accounts are nominally held by others but the control structure is complex, evidence must be examined account-by-account.
For programmatic-manipulation allegations, present strategy source code, trade-logic documentation, and risk-control records showing the strategy had a legitimate commercial purpose.
5. Comparison: China Article 182 vs. SEC Rule 10b-5
If the same conduct is investigated by the CSRC, the U.S. SEC, and/or the Hong Kong SFC at the same time, you face dual-enforcement risk: information you provide to one regulator may be shared with the others and used against you. Read more: Cross-Border Enforcement: SEC & CSRC โ
