Abstract
We use an experiment to estimate the effect of the SEC’s Summary
Prospectus, which simplifies mutual fund disclosure. Our subjects chose an equity
portfolio and a bond portfolio. Subjects received either statutory prospectuses or
Summary Prospectuses. We find no evidence that the Summary Prospectus affects
portfolio choices. Our experiment sheds new light on the scope of investor confusion
about sales loads. Even with a one-month investment horizon, subjects do not avoid
loads. Subjects are either confused about loads, overlook them, or believe their chosen
portfolio has an annualized log return that is 24 percentage points higher than the loadminimizing
portfolio.
