GameStop's $55.5 billion eBay bid baffles markets

GameStop shares dropped more than 10% after CEO Ryan Cohen told CNBC he didn't understand questions about how the video games retailer could possibly finance its surprise $55.5 billion bid for eBay. The offer is many multiples of GameStop's own market value, and Cohen's non-answers have done little to reassure investors that the deal is grounded in anything resembling a plan. Markets are now treating the announcement less as a corporate strategy and more as a riddle.
