Ray Dalio manages monster AUM and much of it is now in All Weather, a passive portfolio that's somewhat better than the standard 60% stocks 40% bonds. It mostly applies a bit of leverage to the bonds to put them on equal footing with the stocks when it comes to portfolio construction. That helps to put equal risk in the asset classes unlike 60/40 which has almost all risk in stocks. It's possible to get 10% return and less than 10% volatility p.a. with such a risk balanced approach.
