Apple shares were stung by a broker downgrade for a second straight week on Monday, sending the stock lower to keep the tech sector under pressure for a second straight session.
Mizuho Securities cut its rating on the iPhone maker to "neutral" from "buy," and reduced its price target to US$150 from US$160 per share.
"The stock has meaningfully outperformed on a year-to-date basis and we believe enthusiasm around the upcoming product cycle is fully captured at current levels, with limited upside to estimates from here on out," said analyst Abhey Lamba.
Last week, Pacific Crest Securities lowered its rating on the stock to "sector weight."
Of the 46 analysts covering Apple, 11 now have a hold rating, according to Thomson Reuters data. There is one "strong sell" rating on the stock and the remainder are "buy" or higher. The median price target of US$160 is up from US$145 three months ago.
Apple shares were down 3.6 percent to US$143.59, the biggest drag on each of the three major Wall Street indexes.
Despite the recent decline, Apple shares are still up more than 23 percent for the year. The stock has added about 185 points to the Dow's climb this year, behind only Boeing, McDonald's and 3M Co.
Tech shares had come under heavy pressure on Friday, as the S&P technology sector dropped 2.7 percent and were down more than 2 percent on Monday, to put the sector on track for its worst two-day performance in almost a year.
Apple slumped on Friday after Bloomberg News reported that iPhones launched later this year will use modem chips with slower download speeds than some rival smartphones.
