<prompt> Human: I just tried to invest in Vanguard 500 Index Admiral Fund VFIAX through my Schwab account and it said that it was closed to new accounts, only existing investors can add funds. Does anyone else see this? Do I have to open an account at Vanguard to buy shares? I would prefer to keep my accounts consolidated.  <response>: If youre investing through Schwab so purchasing this fund isnt fee-free, no reason not to just by SPY instead SPDR SP 500 index. Its the classic SP 500 fund, and has an even lower expense ratio.
