Behavioral Funds

  

Mutual funds in which the manager selects stocks based upon behavioral finance tenets.

Donnie firmly believes that, when investors are experiencing euphoria, they will bid up stock prices, while the opposite is true when they are feeling angst. To capitalize on this theory, he started a Twitter-based behavioral fund whereby he buys/sells stocks based on the general tone of 500 accounts he follows. Donnie's fund, like most behavioral funds, is underperforming the market, but that's way better than, say, trying to govern an entire nation using similar tactics.

01:04

determine the best way to maximize your returns depending on

risky investments but it all comes down to risk reward

02:17

Tolerance in the end if for whatever reason you feel

02:20
