NEW YORK (TheStreet) -- Facebook was a loser in premarket trading on Thursday, falling 1.18% to $31.85 as investors responded to analysts' mixed reviews of the company's prospects.

Wednesday was the first day that companies involved in underwriting the largest-ever tech IPO could issue recommendations on Facebook. Shares of the social networking phenomenon closed down 2.63% in Wednesday trading after a slew of analyst reports struck a generally cautious tone on Facebook.

Facebook shares are down more than 15% since the company's IPO last month.

Shares of key Facebook partner Zynga were also pressured in premarket trading on Thursday, down 1.07% to $5.57.

Investors were underwhelmed by the social gamer's "Unleashed" event earlier this week, which saw Zynga announce several new games and a new social network.

Zynga shares closed down 2.34% on Wednesday.

Qualcomm , which announced plans for a new corporate structure early on Thursday, slipped 0.64% to $54.56 before market open.

Embattled Canadian handset maker Research In Motion , which reports its first-quarter results after market close, was up 0.33% to $9.21 in premarket trading.

Analysts surveyed by Thomson Reuters are looking for RIM to report a loss of 1 cent a share on revenue of $3.11 billion, compared to earnings of $1.33 a share and sales of $4.9 billion in the same period last year.

TheStreet will be live-blogging RIM's first-quarter earnings, starting at 3:45 p.m. EDT.
