Last week marked the sixth consecutive week with a rising New York stock exchange and ended with record highs for both the Dow Jones industrial index and the broad S&P 500 index.
At Monday's close, the Dow Jones industrial index stood at minus 0.8 percent and the S&P 500 index fell 0.3 percent. Nasdaq's composite index held above water, plus 0.3 percent.
Nvidia performed strongly and rose 4 percent, a new record high for the chip giant after several banks raised their target price for the stock.
Among the losers, the retail chain Target stood out, falling 3.8 percent. The pharmacy chain CVS, which fell over 5 percent on Friday after the news that the CEO would be leaving the company, lost another 2.4 percent.
Later in the week, quarterly figures are expected from major companies such as Tesla, Coca-Cola, and crisis-ridden Boeing. The aircraft manufacturer rose over 3 percent after last week's news that the union would vote on a collective agreement proposal that could end the ongoing major strike.
