Anti-Martingale System(redirected from Anti Martingale System)
An investment strategy in which an investor increases the size of his/her investment with each gain. For example, if an investor buys stock at $10 per share and the price goes to $20 per share, he/she may sell the first stock and then buy another stock at $20 per share. In other words, with each profit the investor adds to the size of his/her portfolio, accepting additional risk only with additional earnings. This contrasts with the Martingale System, in which the investor increases his/her risk more with losing investments. Both systems are used in gambling as well as investment.
