The S&P 500 hit a three-week low on Tuesday as weak results and forecasts from a bunch of retailers including Target and Kohl's fanned worries about holiday season sales, while tech stocks continued to slide on concerns about iPhone sales.
Apple Inc's 3.8 percent fall added to the pressure as the stock that led the market through much of its bull run opened at its lowest level since early May, pushing the tech-heavy Nasdaq to more than 7-month lows.
Should Apple's loss hold through the day, its shares would have lost more than 20 percent of their value, or around $250 billion, since closing at a record high on October 3.
Goldman Sachs trimmed its price target on Apple for the second time in just over a week, saying the balance of price and features in the new iPhone XR may not have been well-received by users outside of the United States.
Retailers took a hammering with Target down 9.9 percent after it posted a lower-than-expected third-quarter profit. Home improvement chain Lowe's Cos Inc fell 2.6 percent after it unveiled more restructuring plans in the face of worse-than-expected comparable sales numbers.
Department store operator Kohl's Corp shed 10.9 percent after its full-year profit forecast fell below expectations.
The S&P 500 retailing index shed 3 percent.
"It's a growth related selloff. It's not a specific name. People think growth has peaked and earnings have peaked," said Michael Antonelli, managing director, institutional sales trading at Robert W. Baird in Milwaukee.
"Some of the big retailers are now cracking and that's just adding fuel to the fire."

Signs of slowing demand for Apple's flagship iPhones have wide-ranging implications for technology and internet companies at a time when investors are fretting over peaking corporate earnings growth, rising borrowing costs, and a global economy weighed down by trade tensions.
