Mainland China is the place to be, right? Not according to Peter Stock. The president and chief investment officer of Stock Investment Management says Hong Kong is a better value -- and he thinks the mainland is a bubble slated to burst. He joined CNBC's Mark Haines to tell "Squawk on the Street" viewers which Hong Kong companies' shares are poised to jump.

Stock said that Hong Kong is trading at "16, 17 times earnings," as compared to the mainland's A-share (Chinese common stock) market, trading at "50-plus." He believes continental China is "definitely" due for a correction.
