    A: Your behavior totally explains the house money effect!

    Note: This term refers to the tendency for investors to take more and greater risks when investing with profits. The house money effect gets its name from the casino phrase “playing with the house’s money.” The house money effect forecasts that investors are more prone to buy higher-risk stocks after a profitable trade. Some believe that the house money effect is an example of mental accounting, whereby capital is kept separate from recent profits, leading investors to view said profits as disposable. As a result, they are more inclined to take greater risks with the money.
