Bailey McCann, Opalesque New York: 2021 could be the year where investors remember why they keep uncorrelated strategies in the portfolio, according to hedge fund manager Roy Niederhoffer founder of New York-based R.G. Niederhoffer Capital Management. 2020's rebound in stocks could be giving investors a false sense of security given the potential for inflation as well as continued macro uncertainty. "It's really critical for investors to remember that stocks and bonds can go down together," Niederhoffer tells Opalesque. "A mix of stocks and bonds is not always enough diversification to preserve capital when they are going down together." Indeed, both asset classes did fall during the March crash last year. That event is likely in the rearview for many investors given the scale of the rebound.
