Activist investors want the online marketplace to spin off or sell StubHub, the online ticket reseller, and its classified-ads business because they could be worth more on their own. Elliott said StubHub could be worth as much as US$4.5 billion, and the classifieds as much as US$12 billion. Elliott disclosed a four per cent stake, and Starboard is reported to have also taken a significant stake in the company. eBay shares jumped almost 12 per cent at the news in pre-trading, and are up over six per cent on Tuesday. (Wall Street Journal)
