Sony’s $100 Billion Lost Decade Supports Loeb Breakup

Sony Corp. has a $100 billion reason to consider Daniel Loeb’s breakup proposal.

Loeb, whose Third Point LLC hedge fund just took a $1.1 billion stake in Sony, is pushing the Tokyo-based company to sell as much as 20 percent of its entertainment business and focus on the “considerable and underappreciated value” of its electronics unit. After Loeb’s proposal sparked the biggest rally in Sony shares in more than four years, the $21 billion company still languishes at a cheaper valuation relative to profit than 90 percent of similar-sized consumer electronics makers, according to data compiled by Bloomberg yesterday.
