The lesson of Loki? Trade less
Going back as far as the Norse gods, the market has tricked investors into making rash decisions.
Loki is notoriously malevolent, and no doubt would love to take the wealth of retail investors and set it on fire, if he could. But when faced with such a — shall we say binding? — constraint, what damage could he really do?
One possible explanation for this behaviour is that investors are deeply influenced by what they’ve seen the stock market doing across their lives so far. The economists Ulrike Malmendier and Stefan Nagel have found that the lower the returns investors have personally witnessed, the less they are likely to put in the stock market. This means that bear markets scare investors away from their biggest buying opportunities.
Morningstar found that the gap between investment and investor returns is largest for more specialist investments such as sector equity funds or non-traditional equity funds. The gap is smaller for plain vanilla equity and smaller still for allocation funds, which hold a blend of stocks and bonds and automate away investor choices. That suggests that the investors who are trying to be clever are the most likely to fall short, while those who make the fewest possible decisions will lose out by the smallest amount.
