ETFs offer services and investment flexibility that indexed mutual funds generally do not. We expect that if ETFs offer additional benefits over index funds, such as intra-day and option trading, then certain investors should prefer ETFs, leading to a shift in demand from indexed products to ETFs. We test this hypothesis by examining the flow of funds into, and out of, indexed mutual funds that track the S&P 500, and net creation and redemption levels for the ETF Spider. We find that the demand for the Spider has a significantly negative effect on the demand and, thus, the flow of funds of indexed mutual funds. Moreover, the lowest cost mutual fund provider seems to be exempt from this relationship.
