I've been following (or, trying to follow) the index investing strategy for years on my own, and the final culmination of that was switching to betterment.com for my small savings and retirement accounts (no affiliation). They use MPT and a host of other things to take the decision making control out of the hands of the investor (except for risk tolerance) and provide a really great modern product to do that. And the best part is that it's probably cheaper than just setting up your own online brokerage account and paying fees for transactions. They charge a percentage fee for assets under management like a normal advisor might. Anyway, I just feel strongly that the robo advisor category is major win for average people trying to invest and I wish more people looked into it rather than getting killed in the market or paying high fees to managers. Lets you just put your money in and just focus on your own life and achieving your goals, which is often the point of investing for an average person. Wealthfront is also good, but from what I understand betterment has better returns (and I prefer their interface)
