Ok, I just checked again. I looks like I ditched the 1.16% expense fund already. Those I have left are below with my % allocation and expense.
VANGUARD TARGET RTMT 2040 INV 15% expense 0.18%
SCHWAB TOTALSTOCK MKT IDX 20% expense 0.09%
VANGUARD 500 INDEX ADM 25% expense 0.05%
VANGUARD MID CAP INDEX ADM 20% expense 0.09%
VANGUARD SMALL CAP INDEX ADM 20% expense 0.09%
These really are the lowest expense funds available.
How do I know if this is a good mix? Should I get rid of VANGUARD TARGET RTMT 2040 INV (highest expense) and re-allocate between others?
How do determine if this a good diversification? The all have very similar returns, but it's a mix of small, mid, and large caps, plus a target date.
