Definition of '2% Rule'
A trading practice where an investor should concentrate no more than 2% of available capital on a single trade. To follow the 2% rule an investor first calculates 2% of the available trading capital, called the capital at risk. Brokerage fees for buying and selling shares are then factored into the capital at risk, and this figure is divided by the current share price. The resulting figure is the total amount of shares that can be purchased. If market conditions change and result in the trader losing the total value of that trade the downside exposure is only 2%, since the value of the original trade was limited to 2% of the total amount of trading capital available.
