NEW YORK (TheStreet) - Shares of security specialist FireEye , which reported its first-quarter results on Tuesday, plunged 13.95% to $31.95 as investors responded to the company's weaker-than-expected guidance.

In a note released on Wednesday, FBR Capital Markets lowered its FireEye price target to $70 from $105, citing "multiple compression in light of recent market volatility". FBR, however, maintained its 'outperform' rating on the stock.

FireEye was also one of the most active pre-market Nasdaq stocks on share volume of 305,662.

Yahoo! shares dipped 0.08% to $36.46 in pre-market trading. The Internet giant holds a 24% stake in Chinese online retailer Alibaba, which filed its prospectus for an eagerly-anticipated IPO with a $1 billion placeholder on Tuesday.
