I'd recommend Fidelity. They have some no-fee type mutual funds of different risk levels.
I was advising someone who was 'married' to Fidelity.
During the Bush/Paulson crash, Fidelity moved FINANCIALS into a gold mutual fund, killing all the profit I had carefully squeezed out of a down ward market.
I can no longer cannot trust them. the State of NY was able to sue Fidelity about that incident, 25 million to the injured parties.
You look at the components of the mutual fund, it looks great, and they can move ANYTHING into your supposed X fund, so its underlying weakness becomes unrelated to the supposed X, and the Z portion tanks.
Pick your own damn stocks.
