Market Manipulation and Insider Trading
About This Lesson
Manipulation and insider trading are the headline-grabbing prohibited activities, and the SIE tests them at the recognition level: given a scenario, can you name the violation?
What you'll cover
- Manipulation schemes: pump and dump, front running, marking the close, wash trading, matched orders, painting the tape, capping, pegging, and spoofing
- Insider trading under Rule 10b-5: material nonpublic information and who counts as an insider
- The two theories of insider trading: classical and misappropriation
- Tipper and tippee liability, and information barriers
- The penalties: treble civil damages and the criminal maximums
For insider-trading scenarios, two things have to line up: the information must be material and nonpublic, and the person trading must have a duty they are breaking. Keep both in mind and the scenarios get much easier.
Market Manipulation
Market manipulation is any deliberate attempt to interfere with the free and fair operation of the market, usually by faking price, volume, or demand. The SIE wants you to recognize the named schemes. Start with the most common ones:
- Pump and dump: hyping a stock with false or misleading positive statements to inflate the price, then selling into the spike.
- Front running: trading ahead of a known large customer order to profit from the price move that order will cause.
- Marking the close (or open): placing trades right at the close or open specifically to move the reported price.
- Churning: excessive trading in a customer's account to generate commissions rather than to serve the customer.
- Backing away: a market maker refusing to honor its own published, firm quote.
A second cluster of schemes works by manufacturing fake trading activity or pinning a price in place.
Wash trading
Buying and selling the same security at the same time (often through coordinated accounts) so ownership never really changes. It pumps up volume to fake demand.
Matched orders and painting the tape
Matched orders are pre-arranged trades between colluding parties to create a false picture of activity. Painting the tape is running a series of trades that print to the tape to give the impression of heavy interest.
Capping and pegging
- Capping: placing sell orders to keep a price from rising, often to stop a written call from going in-the-money.
- Pegging: placing buy orders to keep a price from falling, often to protect a written put.
Spoofing and layering
Entering large orders you intend to cancel before they execute, faking supply or demand to nudge the price. It is prohibited under the Exchange Act and Dodd-Frank.
Free-riding
In a cash account, buying a security and selling it before ever paying for the purchase. It violates Regulation T and can freeze the account for 90 days.
Manipulation Types: Quick Reference
| Practice | What It Is | Key Identifier |
|---|---|---|
| Wash trading | Buy and sell same security simultaneously; no real ownership change | Fake volume, no economic purpose |
| Matched orders | Pre-arranged trades between colluding parties to inflate activity | Coordinated, two or more parties |
| Painting the tape | Executing a series of real trades to create false appearance of activity | Actual trades, designed to mislead |
| Capping | Placing sell orders to prevent price from rising | Keeps price DOWN, benefits short calls |
| Pegging | Placing buy orders to prevent price from falling | Keeps price UP, benefits short puts |
| Spoofing/layering | Placing large orders with intent to cancel before execution | Orders canceled before fill |
| Front running | Trading ahead of a large customer order using knowledge of pending order | Uses customer order information |
| Churning | Excessive trading in a discretionary account to generate commissions | Excessive activity, customer harm |
An employee of a broker-dealer learns that a large customer is about to place a major buy order. The employee buys the stock for their personal account first. This is an example of:
An investor places multiple large buy orders with no intention of executing them, hoping to drive up the price of a stock. This practice is known as:
Insider Trading
Insider trading means trading on material, nonpublic information in breach of a duty. It is prohibited under Rule 10b-5 (the SEC's anti-fraud rule under Section 10(b) of the Securities Exchange Act of 1934). Two pieces define it:
- Material: information a reasonable investor would consider important, earnings before release, a pending merger or tender offer, an FDA approval, a major management change, a bankruptcy, or a stock-split or dividend change.
- Nonpublic: not yet released to the general public.
The two theories
Courts reach insider trading two ways. Under the classical theory, a corporate insider breaches a duty to the company's own shareholders by trading on its secrets. Under the misappropriation theory, an outsider breaches a duty to the source of the information by trading on it, which is why you do not have to be a corporate insider to be liable.
Who counts as an insider
- Corporate insiders: officers, directors, and 10%+ shareholders.
- Temporary insiders: attorneys, accountants, and investment bankers who receive the information through their work.
- Anyone who misappropriates material nonpublic information, no corporate role required.
Information barriers
To keep inside information from leaking across a firm, broker-dealers maintain information barriers (sometimes called Chinese walls) between departments that may hold material nonpublic information, like investment banking, and those that make trading recommendations, like research and retail.
A corporate officer privately tells a friend that the company will report unexpectedly poor earnings next week, and the friend sells their shares before the announcement. Under insider trading law:
Penalties and Liability
Civil penalties: Up to 3× the profit gained or loss avoided (treble damages), enforced by the SEC
Criminal penalties: Up to $5 million fine and 20 years imprisonment for individuals; up to $25 million for firms
Controlling person liability: Firms that fail to prevent insider trading by employees can face civil penalties of up to the greater of $1 million or 3× the profit/loss
Under the Insider Trading Sanctions Act, civil penalties for insider trading can be as high as:
Chapter Essentials
Market manipulation is any deliberate interference with fair pricing, and the SIE tests it by name. Schemes that fake activity or demand include wash trading (no real ownership change), matched orders (colluding parties), painting the tape (a run of trades to look busy), and spoofing (large orders meant to be canceled). Schemes that pin a price include capping (sell orders to hold it down, protecting short calls) and pegging (buy orders to hold it up, protecting short puts). And schemes that exploit order flow or hype include front running (trading ahead of a known customer order) and pump and dump (inflate on false news, then sell).
Insider trading is trading on material, nonpublic information in breach of a duty, prohibited under Rule 10b-5. It reaches corporate insiders (officers, directors, 10%+ holders), temporary insiders (lawyers, accountants, bankers), and anyone who misappropriates the information, and both the tipper and the tippee can be liable. Penalties are steep: civil up to three times (treble) the profit gained or loss avoided, criminal up to $5 million and 20 years for an individual ($25 million for a firm), and controlling firms that fail to prevent it face the greater of $1 million or 3× the profit or loss.

The reliable gotchas in this chapter:
• Spoofing cancels its orders; painting the tape uses real trades. Both fake activity, but spoofing never intends to execute, while painting the tape actually fills the orders. The phrase "no intention of executing" points to spoofing.
• Front running uses a customer's order; insider trading uses the company's secret. Trading ahead of a pending client order is front running, not insider trading. Insider trading turns on material nonpublic information about the issuer itself.
• Capping holds a price down (helps short calls); pegging holds it up (helps short puts). Easy to flip, so anchor on which option position each one protects.
• You do not have to be a corporate insider. Under the misappropriation theory, anyone who trades on material nonpublic information in breach of a duty is liable, and the tipper is liable right alongside the tippee.
• Civil penalty is treble, 3× the profit or loss. Not 2× and not 5×. Criminal maximums are $5 million and 20 years for an individual, $25 million for a firm.
• Free-riding is a cash-account problem. Selling before paying for the buy violates Regulation T and freezes the account for 90 days; do not confuse it with the manipulation schemes.
