Tech Five: Amazon, Broadcom falling

Amazon's stocks dip in pre-market tradingInvestors started this week with skepticism about technology stocks. Here are five tech stocks to watch Monday morning:

Amazon. Shares of the online retailer are down more than 6% in pre-market trading. It had a rough ride last week after predicting an operating loss in the current quarter although its first-quarter net income rose 32%.

Broadcom. The semiconductor manufacturer saw its shares dip nearly 5% in pre-market trading, following a modest first-quarter 2014 earnings report last week. Company CEO Scott McGregor said the overall results were “ahead of expectation” and “driven by strength in Broadband and Infrastructure, stronger-than-expected gross margins and continued operating expense discipline.” He said he expects technology upgrades in the current quarter.

Tesla. Shares of the luxury electric vehicle maker dropped nearly 3% in pre-market trading. The company, which has seen stock prices generally rising, got unofficial support last week from the U.S. Federal Trade Commission in its battle to sell vehicles directly to consumers when three FTC staff directors wrote on the agency’s blog that state laws barring direct auto sales is “bad policy.”

Facebook. The social media giant, which enjoyed a bounce last week’s from a heady first-quarter earnings reports, had its shares dip 1.5% this morning. The compnay blew away investors with its hefty mobile ad sales, which accounted for nearly 60% of its ad revenue.

eBay. The trading website is slated to release its first-quarter earnings  Tuesday. One of its companies, eBay Enterprise,  announced  a new Ship-From-Store offering Thursday  that it says will lower shipping costs for retailers and brands.
