I personally use Vanguard ETFs which are known to be one of the oldest, consistent annual return ETFs, 7% minimum annual returns. Some of the best known tickers for Vanguard mutual funds are VISVX, VLCAX, VTSAX, VWINX.

You can buy ETFs for vanguard ticker from robinhood as well without any cost. Vanguard stock ETFs have ticker (VTI... etc) Vanguard themselves offer mutual fund for same ETFs for free if you invest $10K or more and sign for electronic statements.

I use optionshouse as my broker. They have one of the best platform for options trading (risk analysis, pre and after hours trade window, realtime news...).  They do have fee but not as bad as other big brokers/traders.
