US stocks mixed as trade questions linger

Boeing propelled the Dow to a record high, but US stocks were otherwise under pressure with investors still racked by uncertainty over trade talks and as political tensions in Hong Kong flared up. Activity on Wall Street was subdued owing to the Veterans Day holiday, with equities trading but the Treasury market closed. The S&P 500 fell 0.2 per cent, while the Nasdaq Composite eased 0.1 per cent lower coming off their record highs on Friday.
