For those of you who may not be aware, Ray Dalio, founder of Bridgewater Associates (reputed to be one of the largest and longest lasting Hedge fund in the world) wrote a book in 2011, called Principles. In this he has a little blurb on diversifying which most attribute to as the best form of risk management. 197d) Don’t bet too much on anything. Make 15 or more good, uncorrelated bets. Unfortunately for the rest of us, Mr. Dalio true to the title of book, keeps the entire book very abstract that forces the user to ponder those 15 uncorrelated income streams. Experts have theorized that at 15 assets would reduce risk by 80%. Over last few years of trading, I've tried to diversify my trading strategies (and also business ventures) to achieve uncorrelated income streams. As a trader, some of the areas that I see slight levels of uncorrelations from Stocks/Equities - Stocks & Equities - Hedging with Options - Emerging Markets Equties - Volatility Trading and Vol Arb - Commodities Trading (Crude / Metals) - Hedging of Commodities - Bonds and Fixed Income - Real-Estate To a certain extend most of these correlate to the economy (look at the market, today). I'm curious what others see as Uncorrelated Asset classes and income streams that are time tested through good times and bad times. PS: This topic was briefly discussed in a previous post, 5 years ago. However, very little specifics https://www.elitetrader.com/et/threads/trade-like-ray-dalio.276864/ Times have changed and everything seems to be correlated.
