SmartStops comment: just came across this interesting point that indicates the DIY’ers are doing better then clients of Financial Advisors:
.. These added services (education etc. from brokerage) seem to be helping, as self-directed investors tend to see quite a bit of success, even outperforming investors with financial advisers in many cases. According to SigFig, a website that helps investors manage their money, investors who were clients of financial advisers had returns of 14.1 percent in their portfolios in 2013, while self-directed investors saw 17.1 percent returns.
