Well, you certainly have a plate of stinking poo there. Even their core bond fund underperformed its index. The stable value is almost 1 percent below the Prudential stable value fund in my 457 plan.
The first question I would ask myself if I were in your shoes would be how much do I have in this account and how much of my total assets does this account represent? As long as I had other accounts to use for asset allocation, I would cherry pick the best of what is offered. The index accounts are a good start. The index equity funds I would consider would be the S&P 500, the broad market index fund, and the small/mid cap index fund. I would also look at one managed fund, the T Rowe Price Small Cap Value fund. Small caps tend to be more volatile, which you are trying to avoid, so I would consider only a small percentage in my overall asset allocation.
Fidelity Puritan is similar in philosophy to Vanguard's Wellington. It's a balanced fund, but in my opinion, it owns riskier equities. For what you want, some of that would be ok. The MP Conservative Growth Fund is a fund of funds. That's multiple layers of expenses. I would ditch that one. I don't care for any of their international or specialty funds. You can do much better outside of this account.
So generally, I think you are headed in the right direction. If you look at your overall asset allocation and tweak your choices, you will have made the best of what's offered.
