Do you allocate your 401(k) investments based on how funds' names are listed alphabetically? Sounds crazy, right? Well, it could be that because it can be difficult to make those kinds of decisions, absent other information that's really helpful, you could scan a list of funds arranged alphabetically and well... Click.

In a research paper titled, Alphabeticity Bias in 401(k) Investing, the authors say structural factors which cause irrational investment in defined contribution savings plans are of great concern. Using a proprietary database of 401(k) plans they show that alphabeticity - the order that fund names appear when listed in alphabetical order - significantly biases participants' investment allocation decisions. While there appears to be a larger impact as the number of funds in the plan increases, this bias is strong even when relatively few funds are available in the plan menu. Importantly, their findings suggest that a more strategic ordering of funds could result in favorable outcomes for participants.
