Tech Five: Sony to delay PS4 sales in China

The debut of Sony's video game console in China will have to wait a little longer. Let's look at the five technology stocks to watch Thursday:

Sony. The electronics giant has postponed the launch of its PlayStation 4 video game console in China, reports Reuters. A company source in China cites prolonged negotiations with the country as a reason for the delay.

Facebook. The social network says video posts created by its users surged 75% globally, while nearly doubling in the U.S. The company also says the amount of video in News Feeds has more than tripled year over year.

Samsung. The tech titan's fourth quarter profit plunged 37% from a year ago, reports Bloomberg, but it was strong enough to beat estimates. Meanwhile, total sales were down 12% year-over-year.

Google. Investment firm Stifel Nicolaus downgraded the stock to "hold," reports CNBC. However, shares are only down 0.5% in pre-market trading.

Yelp. The Federal Trade Commission has ended its investigation into the online recommendations service over business reviews. In a blog post, Yelp says the FTC found no wrongdoing.
