Investors should sell the dollar, as chances grow for a decisive win by Democrat Joe Biden at next month’s US presidential election and as progress continues towards an effective vaccine against Covid-19, Goldman Sachs strategists said on Friday. Business Insider quotes Goldman as saying the chances of a so-called “blue wave” have risen to more than 60%, based on Biden’s growing lead over President Donald Trump in the polls, suggesting that investors should short the dollar against a volatility-weighted basket made up of the South African rand, Indian rupee and the Mexican peso, as well as buying Australian and Canadian dollars and the euro.
