SIMPLE IRA is through Wells fargo with 40K in it and has done well. ANWPX and DWGAX are the holdings in that account. Fees are low and that gets a 3% match through my employer.
Earlier you mentioned a 35% cumulative gain over 5 years. That's about half the U.S. stock market return. If you had invested in a total stock market fund, your gains would have been closer to +75% for the past 5 years.
I'd strongly recommend you look at the expense ratios in your plan, and put everything in the lowest expense ratio fund. In every case I've seen, that's always a low cost, passive index fund. The expense ratio is what percent of your money the fund silently takes from you every year. Your current funds are higher cost:
ANWPX has an 0.76% expense ratio
DWGAX has a 1.30% expense ratio
Good expenses are below 0.30%, and there's a number of funds below 0.10%.
There's also some good books which base their conclusions on historical stock market data. "A Random Walk Down Wall Street" was originally published in 1973, and it's 12th edition came out last month. Any library will have a copy, so you take take a look for free.
