Default investment acceptance increases for target date funds with lower expense ratios, lower levels of equity risk and higher relative performance, according to a new Morningstar report.
But expense ratio clearly has the largest effect among those three factors, David Blanchett, head of retirement research at Morningstar Investment Management, says in the report, "Made to Stick: "The Drivers of Default Investment Acceptance in Defined Contribution Plans."
The "expense ratio relation is notable because it suggests funds with higher expense ratios not only have a higher level of expenses to overcome to generate alpha, but they also may result in lower levels of default investment usage," Blanchett writes. That "creates an additional implicit cost for participants, since those who self-direct their accounts tend to experience lower returns than those who invest in professionally managed investment options."
The "negative expense ratio/default investment acceptance relationship is especially interesting because higher expense ratios already create a higher explicit return hurdle," he writes. His research suggests there is an "additional implicit cost as well with the lower potential default investment acceptance."
A fourth factor explored by Blanchett was the size of the sponsoring TDF company, which is "assumed to be a proxy for general brand awareness," he points out in a related blog post.
