It may not be as far-fetched as the CIA dispatching a celebrity tabloid show host and his producer to assassinate North Korean dictator Kim Jong Un. Yet a 43 percent rally in the shares of money-losing Sony Corp. is pretty remarkable.

Sony has delivered a one-year return that's on par with that of Apple Inc. and is one of the top performing stocks in Japan in 2014, easily beating gains of about 9 percent by the Nikkei average and Topix benchmark indexes.

This is the same Sony that's forecasting to lose ¥230 billion for the fiscal year ending in March 2015. Sony Pictures Entertainment, meanwhile, has had sensitive corporate emails and film properties hacked and publicized, much to the embarrassment of top executives.
