Billionaire investor and founder of hedge fund Bridgewater Associates, Ray Dalio has shared his simple investing mantra to build an all-weather portfolio that can balance risk in amid a volatile equity market. Speaking to Investopedia on a range of topics, including how he ensures risk balance and steady returns, Ray Dalio noted that his mantra is “investing in 15 good uncorrelated return streams, risk-balanced”. An uncorrelated asset is an investment that has little to no correlation with the traditional asset classes such as stocks and bonds, hence stabilising your portfolio during a market downturn.
