Ray Dalio's All Weather Strategy

With just a few lines of code, I have implemented  Ray Dalio's All Weather Strategy.

The strategy is based on a target portfolio of weighted etfs representing different markets:

  • 30% Vanguard Total Stock Market ETF (VTI)
  • 40% iShares 20+ Year Treasury ETF (TLT)
  • 15% iShares 7 – 10 Year Treasury ETF (IEF)
  • 7.5% SPDR Gold Shares ETF (GLD)
  • 7.5% PowerShares DB Commodity Index Tracking Fund (DBC)

The rules are ridiculously simple, since all there is to do is rebalancing the portfolio once a year, to the fixed target weights.

The attached backtest shows, that the strategy works quite well and with a relatively low drawdown and low interest rates, you can even use some leverage. 

Feel free to comment and improve.

Somewhere or other on my website you will find a python standalone interpretation of the all weather strategy. I chose, a la Dalio, to adopt some bond leverage although arguably an allocation to the long bond is leverage enough.

Google all-weather-portfolio-1928-2018. I used the T Bill rate, bond futures and total returns for the S&P 500 as extended.  You will also find some arguments on my website as to why (in my opinion) rising interest rates will not screw the strategy provided it does not happen too fast (as in the Volker period).

Nice strategy.

Personally I do not favour commodities. But that is only my view. At least stocks and bonds have an obvious upwards bias. No so commodities over time.

But who am I to say....

Thanks for sharing! That beta (-0.018 !!) is pretty amazing, given the low rebalancing frequency. I think I'm going to manually implement this for my 401k for this year.

Awesome strategy; this definitely inspired me to try something similar!

For anyone interested in this, it's also worth exploring other fixed portfolios. Some examples:
