Here's a question I have about that: minimum to invest is $3,000. I invested $3,000 in a Vanguard fund in June. Looked this morning and it's down to $2,974, which is now below the minimum to invest. Will Vanguard want me to divest myself of that fund? I have traditional, Roth IRA's as well as taxable funds already in Vanguard, so it's not the only money I have there.
