"Given that there is no sign of significant changes regarding outsourcing strategy by the major smartphone players, we see limited opportunity for FIH to gain new clients/projects in the near term," Bonnie Chang, an analyst at Yuanta Securities said in a report.

"In addition, FIH had no major breakthroughs in obtaining tablet PC orders, thus missing out on the chance to capitalise on the fast growth of tablet PCs, in our view," Chang said, adding that Yuanta is maintaining a hold rating for the stock.

On Wednesday, Foxconn International, a unit of Taiwan electronics parts maker Hon Hai , posted a net loss of $75.7 million in the second half of last year, as it struggled to regain its footing amid rising costs and falling prices.
