Amid heightened volatility in domestic as well as global stock market, even as investors look to tweak their asset allocation, billionaire hedge fund manager Ray Dalio says that gold should form a part of every portfolio. In an interview to ET Now, Ray Dalio, the founder of the world’s largest hedge fund, Bridgewater Associates said that explained the importance of diversification into various asset classes. “Gold is a diversifying asset and should make for 5-10% of a person’s portfolio. This share could go up later into the cycle,” he said.
