I am a big fan of tactical investment approaches, those that get you out of the market as a large decline is building. That body of knowledge has been popularized by Mebane Faber and Gary Antonacci, both of whom have books and SSRN whitepapers. You can Google / Bing them. I have been doing DIY Faber and Antonacci.
Recently, I found professional advisory services that offer money management based on Faber and Antonacci strategies. I am going to split up most of my money and give it to both of these firms. That will reduce the risk of a DIY screw-up, emotionally based decisions, and will make life less stressful generally, though I still have to implement DIY for my employer's retirement plans.
Fee: 1.15% all inclusive (no other hidden fees)
Licenses Gary Antonacci's proprietary "Enhanced Global Equities Momentum" (E-GEM) signals. Regular GEM is detailed in his book. After Shrier's fees are subtracted, E-GEM has a theoretical backtested performance (1971-2015) of 18.25%, with one down year, a loss of less than 1%, which was 2008. The maximum temporary drawdown was -24%. The improved E-GEM performance more than pays the Adviser fees, over time. Theoretically.
18.25% is huge. $10,000 in 1971 turned into $1.89 million. Even if you captured only half of that in reality... $944k... that still is a killer 16.44%. The S&P500 from 1971-2015 returned 10.1% during 1972-2015, and had nine calendar years with losses, the worst year was a withering -37%.
The DIY GEM, which anyone can do yourself (I verified independently that it works), returned 16.8% over the same 1971-2015 period. Also killed a 100% passive stock allocation.
Fee: 0.25% robot advisor
Mostly based on Mebane Faber's 5-fund mimic of the Ivy League endowments, referred to as "IVY-5", with a mix of 10-month moving average risk control and Gary Antonacci style momentum risk control. The portfolio spend more time in cash than Antonacci. The risk and returns are less. The backtest is posted here, go down to bullet point 4.9. The results match the returns of the 100% S&P500 allocation, around 10% during 1992-2013, but much less risk of loss.
If you're going to go with a robot... go with this one. NOT Betterment, not WealthFront. Those are dumb, passive robots. They will stare in the face of a withering market decline (the stuff since August 2015 is just a warm up), and just rebalance you on the way down. They will not get you out to cash.
Faber and Antonacci do so well because they aim to "win by not losing".
