Asset allocation defies norms with only zero, infinite risky investment options.
The study looked at how people invest their money in risky assets when they are afraid of losing money. They found that with this fear, people either don't invest at all, invest a lot, or even borrow money to invest. This goes against the usual way people think about investing when they are worried about losing money. So, it seems that when it comes to investing for a short time, it's better to use a different way of thinking about risk than just being scared of losing money.
