I bought one Google April 560 Call today just to test it out. News must have leaked out because Google stock price has been up 20+ points for the last 2 days. Someone on the chat room said that there was a 700,000 shares block traded around 3:30pm today. It must be some insider trading. A $400 Million gamble, I don't think so.
China will simply block google.com.hk the same way it blocks Google.com, Wikipedia.org, Twitter.com, Facebook.com and many other US web sites from being accessible from China.
