<prompt> Human: Im wondering why this sub recommends Vanguard more often. However, there are very posts that says Charles Schwab has the lowest expense ratios. Is there a catch we dont know about?  <response>: Vanguard, Schwab and Fidelity are all good low-fee options. Schwab has some of the lowest fees right now, but theyre all in competition with each other for low fees and that could change at some point.Vanguard is well-liked because of its role in the popularization of index funds and the fact that its a mutual company owned by the shareholders of its funds.
