My wife started a new job recently and we're looking at getting into the best fund possible. It's through Wells Fargo, and unfortunately, a lot of the options don't have any information associated with them (e.g. I can't click a link that tells me anything about the fund).
The best of the ones that I AM allowed to get additional information seems to be RFNEX, which is an American Funds large cap, with a .66 expense ratio.
That said, one that didn't have extra info and intrigued me was BlackRock S&P MidCap Index. Unfortunately, Google didn't find me a stock symbol for this one, but I assume it's an index of the S&P 400 midcap. The large cap version (WFSPX) is .07 expense, so I'd imagine this is similar. But would a MidCap be something we'd actually want to invest ~$20k of 401k money a year into, with a FIRE goal of 8-10 years? It seems like MidCap would be significantly more volatile.
The other funds are:
Wells Fargo Advantage Asset Alloc Adm
ASTON/Fairpointe Mid Cap N
Federated Kaufmann R
Aston/Tamro Small Cap/N
Dodge & Cox International Stock
Eaton Vance Large-Cap Value A
American Funds Fundamental Invs R4
Goldman Sachs Mid Cap Value Inst
Oakmark Equity & Income I
American Funds Growth Fund of Amer R3
Wells Fargo Enhanced Stock Market CIT N
Wells Fargo Stable Return Fund N
TCW Total Return Bond I
WF/Causeway International Value CIT N
JPMorgan Large Cap Growth R5
Goldman Sachs Small Cap Value Inst
Goldman Sachs High Yield A
WF/BlackRock Russell 2000 Index CIT N
WF/BlackRock S&P MidCap Index CIT N
WF/BlackRock Intl Eq Index CIT N
Baron Growth Institutional
And then the default which is just a mashup of about 20 other mutual funds.
