US equity markets were again weaker on Monday, investors worried that tariff policy uncertainty would tip the economy into a recession, something President Donald Trump did not rule out over the weekend in an interview. 'Risk-off' sentiment can definitely be seen in US market trading. The Dow fell 890 points or -2.08%, the 30-stock index dragged down by Nvidia, Goldman Sachs and Apple, down -5.07%, 5%, and 4.85% respectively.
