(CNBC) — U.S. stocks surged on Tuesday, with the S&P 500 and the Nasdaq Composite extending gains into a fourth day, as investors embraced earnings from corporations including Apple, Texas Instruments and United Technologies.
"When you look at Apple, it almost takes your breath away. It's such a big company, and so important to the S&P 500 and the technology sector, so it has a lot of weight," said Hugh Johnson, chairman of Hugh Johnson Advisors, who owns Apple shares, but would not purchase more at current prices.
Verizon Communications gained after the wireless carrier tallied revenue above estimates; Coca-Cola and Chipotle Mexican Grill were active to the downside, as the beverage maker and Dow member cited currency headwinds in cutting its growth outlook, and the burrito chain signaled increased growth in quarterly sales would not continue forever.
