Types of Market Manipulation
Wash Trading
Wash trading involves buying and selling the same security to create the illusion of market activity.
Definition: Simultaneously buying and selling the same security
Purpose: Create appearance of active trading
Result: No change in beneficial ownership
Violation: Securities Exchange Act, FINRA Rules
Example: A trader sells 1,000 shares to a related account and immediately buys them back, creating artificial volume.
Matched Orders
Matched orders are prearranged trades between parties with no real change in ownership.
Orders entered knowing a matching opposite order exists
Creates misleading appearance of active trading
Often used with wash trades
Painting the Tape
Painting the tape involves executing a series of transactions to create the impression of active trading.
Definition: Transactions creating misleading activity appearance
Purpose: Attract other investors to trade
Name Origin: From ticker tape showing trade activity
Note: Painting the tape and matched orders often work together to manipulate prices.
Pump and Dump
Pump and dump schemes artificially inflate a stock's price through false promotion, then sell at the inflated price.
Pump: Spread false positive information to inflate price
Dump: Sell shares at artificially high prices
Result: Innocent investors left holding devalued stock
Spoofing and Layering
Spoofing involves placing orders with the intent to cancel before execution.
Definition: Placing non-bona fide orders to move prices
Intent: Cancel before execution
Purpose: Manipulate other traders' behavior
Layering is a form of spoofing where multiple orders are placed at different price levels:
1. Place large orders on one side of the market
2. Execute smaller order on opposite side at better price
3. Cancel the large orders
Example: Place large sell orders to push price down, buy at lower price, cancel sell orders, price rises.
Front Running
Front running is trading ahead of a customer order to profit from the expected price movement.
Definition: Trading ahead of known customer order
Who: Broker-dealer or representative
Purpose: Profit from price impact of customer order
Violation: Breach of fiduciary duty
Example: A broker learns a client will buy 100,000 shares. Before executing the client's order, the broker buys shares for their own account, knowing the large order will push the price up.
Marking the Close/Open
Marking the close (or open) involves placing trades near market close (or open) to influence the closing (or opening) price.
Marking the Close: Trades at end of day to affect closing price
Marking the Open: Trades at start of day to affect opening price

Portfolio valuations
Index calculations
Options settlement
Performance benchmarks
Churning (Excessive Trading)
Churning is excessive trading in a customer's account to generate commissions.
Definition: Excessive trading for commission generation
Control: Broker must have control over account
Intent: Generate commissions, not serve customer

Who: Market makers
