Samsung announced today that it will undertake a massive $2 billion stock buyback. This would make it the company's second-largest buyback ever, the first one to have been initiated since 2007, of about 1.65 million common shares and 0.25 million preferred shares.

The Korean giant is taking steps to ensure that its stock price doesn't sink further (down 12% in 2014). Some major restructuring is happening at Samsung, with the mobile portfolio getting a 30-40% cut and several services (such as ChatOn) getting shut down permanently.

Samsung's investors and board members certainly do hope that this enough to get their company back on track.
