I like Fidelity mutual funds because they have low costs. As you know mutual funds are collections of large numbers of quality stocks--100's--- so they are well diversified. I like the following Fidelity mutual funds and their average annual returns over the last ten years averaged.
FSPHX. 12.71% FSRPX. 13.03% FDFAX. 10.79% FSCKX. 14.53% averaged over 4 years fund has existed HDV. 12.82%--ETF of high quality higher dividend stocks, it has almost doubled in 6 years!
I researched all of these funds or ETFs at Fidelity before purchasing and they are all rated 4 or 5 stars by Morningstar rating system where 5 is the highest! If you research them at your broker it will also show you online a graph of what $10,000 invested over the last ten years would be worth ten years later! Most of these funds have tripled your money or more over the last ten years! I hope this helps!!
I hope my mutual fund suggestions and recommendations were okay for you and not too simple! I don't mean to tread on your toes, just trying to help out! Hope I helped!
