What Is Trade Churning?
Churning is trading your account not because the trades help you, but because each one pays the broker. The tell is activity that has no relationship to any coherent strategy — positions bought and sold within weeks, the same security cycled in and out, commissions quietly consuming the account while your balance shrinks.
Under FINRA rules, a broker must exercise control or de facto control over the account and engage in trading that is excessive in light of the client's investment objectives. Courts and arbitration panels evaluate churning using two key quantitative metrics: the turnover ratio (how many times the portfolio is bought and sold each year) and the cost-to-equity ratio (how much the account must earn just to break even after commissions).
Warning Signs
Constant Trade Confirmations
Confirmations arriving constantly for trades you did not ask for or understand.
High Fees Relative to Account
Commissions and fees that consume a large share of the account each year.
In-and-Out Trading
The same position bought, sold, and repurchased repeatedly without a clear reason.
Losses in Rising Markets
Your balance shrinks even in periods when the market rose significantly.
How Churning Damages Are Calculated
In a churning case, damages typically include:
- Excess commissions: The difference between what you paid and what a reasonably managed account would have cost
- Margin interest: Interest charges generated by unnecessary trading on margin
- Tax consequences: Short-term capital gains taxes that could have been avoided with a buy-and-hold strategy
- Lost opportunity costs: What the account would have earned in a suitable, properly managed portfolio
Key Quantitative Tests
Arbitration panels rely on two well-established metrics:
- Turnover Ratio: The annualized ratio of total purchases to average equity. A turnover ratio above 6 is generally considered excessive for any account; ratios of 2–4 may be excessive depending on the client's stated objectives.
- Cost-to-Equity Ratio: The annualized total costs (commissions, markups, margin interest) divided by average equity. If the account must earn 12%+ per year just to break even, the trading is presumptively excessive regardless of market conditions.

Signing trade confirmations does not necessarily mean you authorized the trading strategy. If your broker exercised de facto control over investment decisions and the overall pattern of trading was excessive, you may still have a viable churning claim.
Yes. In fact, a discretionary account — where the broker has written authority to trade without your prior approval — makes the control element easier to establish. The question becomes whether the trading was excessive given your stated objectives.
FINRA's eligibility rule generally requires that claims be filed within six years of the events giving rise to the dispute. However, the sooner you act, the stronger your position.
