Baidu, Amazon, Facebook: Tech Premarket

NEW YORK ( TheStreet) -- Baidu ( BIDU) shares plunged in pre-market trading, weighed down by the company's weaker-than-expected first-quarter results.

However, the Chinese Internet search giant reiterated its second-quarter revenue guidance when it released its results after market close on Thursday.

Baidu shares tumbled 8.71% to $84.30 before market open.

Amazon ( AMZN) was another loser, slipping 1.14% to $271.58 after the Internet retailer noted slowing unit growth in its first-quarter results.

Facebook ( FB), which reports its first-quarter results next week, crept up 1.76% to $26.60. The social network was also one of the most active pre-market Nasdaq stocks on share volume of 299,773.

Zynga ( ZNGA) rose 0.96% to $3.16, while Apple ( AAPL) was up 0.31% to $409.66.
