Can Expense Ratios Signal Performance? An Analysis of Equity ETFs & Mutual Funds

This study examines the impact of the emergence of exchange-traded funds (ETFs) as an alternative investment vehicle to mutual funds. As the number of ETFs continues to rise, we investigate potential risks and disadvantages posed by ETFs in comparison to traditional mutual funds. We compare the returns, performance, and expense ratios of ETFs to those of mutual funds. We find that expense ratios are positively correlated with actively managed mutual fund returns and that passive funds have outperformed active funds since their inception. There is downward pressure on mutual fund fees over time, suggesting increased competition between mutual funds and ETFs. We also find, up to a certain threshold, actively managed funds are worth their costs.
