I have a T. Rowe Price ROTH IRA invested in their 2040 target retirement fund (TRRDX). I just tried out Stockchoker (it is kind of fun although slightly painful because I think there will always be a fund that outperformed yours!) and learned that I would have done better had I invested it in VTSMX (15,189.64) vs what I've earned (12,922.83). This is starting from $7056 in Oct 2009. I'm fine with the returns I've gotten as they were pretty good, however the expense ratio is high and may account for a decent amount of that discrepancy in gains. The expense ratio is 0.75%. And I know how it can add up over time. I think the reason I went with TRP originally was I started with small monthly automatic contributions and I didn't have the minimum necessary to start a Vanguard fund back in the day. I can't remember why I went with TRP instead of Fidelity, but it doesn't really matter now.
Anyway it's the expense ratio that's making me think of moving (or if you have a suggestion for something good with lower expense ratio at TRP too) Also I think I can contribute to the ROTH this year because our income is lower this year.
I'm thinking I should roll it over into Vanguard or Betterment. I also have an existing Fidelity account (trad IRA). Any opinions? I don't mind rebalancing myself, and reviewing my investments periodically. I do like Betterment's UI, but they cost more. And with things like Personal Capital I can view all my investments in their pretty UI.
Your first mistake is comparing the return from a stock/bond fund to a 100% stock fund.
Look at Vanguard's 2040 fund and check the performance from when you invested in 2009 through today and compare that to your TROW fund. It will likely be very close.
In the long run, fees will be important if they are significantly higher for a fund that has the same allocation as another fund with lower fees (remember that any price data you see online is Net of fees... meaning fees are removed automatically from the fund assets).
I'm a fan of Vanguard, but if your motivation is performance, there are comparably good options through TROW too. Also, you can purchase Vanguard funds through TROW, I believe, if you really want something that they offer... just check on transaction fees, if any.
Another option would be to open a new IRA or whatever account at Vanguard/Fidelity and start contributing there going forward.
If you really wish, you can roll over the account (for retirement acounts) or do an "in kind transfer" for a taxable account to move the assets between brokerages.
