Oct 28 (Reuters) - The S&P 500 index and the Nasdaq were weighed down by Amazon and healthcare stocks on Friday, while Chevron lifted the Dow.
Shares of Amazon.com were set for their worst day in nearly nine months, falling 4.7 percent to $780.17 after the online retailer warned heavy investments in the crucial holiday quarter would drag profits.
“Right now we’re seeing this tug-of-war between the sentiment that the earnings recession is ending versus worry when big companies such as Amazon and Apple fail to live up to expectations,” said Art Hogan, chief market strategist at Wunderlich Securities in New York.
