Churning
The Formal Definition
An illegal, unethical practice wherein a financial advisor or broker-dealer excessively executes trades in a discretionary client account primarily to generate transaction commissions and fees rather than to pursue the client's investment objectives.
Churning Indicator: Annual Turnover Rate (Total Purchases / Average Account Equity) > 6.0 AND High Cost-to-Equity Ratio
Cole Barrett's Reality Check
The Unvarnished Bottom Line"Churning is an advisor using your account as their personal ATM. If you give a broker $100,000, and they buy and sell $600,000 worth of stock in six months just to generate $12,000 in trading commissions, that is churning. Your portfolio goes nowhere while your broker buys a new boat with your fee drag."

Real-World Example: Scenario Breakdown
Examining the real numbers for: $100,000 discretionary brokerage account subject to excessive commission generation
| Execution Metric | Fiduciary Fee-Only Advisor (Zero Commissions) | Commission-Billed Broker (Churning Account) |
|---|---|---|
| Fee / Rate | Flat 0.75% annual fee ($750) | $50 per trade commission |
| Spread / Buffer | Executed 4 strategic rebalancing trades during the year | Broker executed 180 discretionary buys and sells during the year |
| Execution / Status | Total transaction fees incurred: $40.00 | Generated $9,000 in trading commissions (9% account drag) |
| Total Cost / Result | Portfolio aligned with long-term compounding | Severe capital erosion caused by broker fee extraction |
How Brokers Weaponize This Term
Traditional wealth management desks hide churning by labeling frequent transactions as 'active risk mitigation,' charging trading commissions on both legs of rebalancing trades.

How does FINRA prove churning occurred?
FINRA evaluates three elements: the broker exercised control over the account, the trading was excessive relative to client objectives (high turnover ratio), and the broker acted with intent to maximize commissions.
What is the turnover ratio threshold that typically indicates churning?
An annual portfolio turnover ratio exceeding 6.0 (meaning the account value was turned over 6 times in a year) is widely viewed by regulators as evidence of churning.
