DEFINITION of 'Double Up'
An investing strategy in which a trader doubles his or her current position in an asset when an adverse price movement occurs. By doubling the risk, the trader hopes to earn a larger return when the security moves in a favorable direction.
BREAKING DOWN 'Double Up'
When executing a double-up strategy, the investor believes that the latest adverse price fluctuation is only temporary and will shortly correct itself. To capitalize on the price reversal, the investor amplifies his or her current position. Doubling up is a risky strategy, but it can yield large returns.
