CAPITAL RAISE. When times are good, cashing in is smart. Media group ViacomCBS, worth over $50 billion, is taking advantage of its surging stock price to sell equity, and $10 billion-plus video-game retailer GameStop may do the same. The opportunity is clear. Over the past three months, ViacomCBS stock has more than doubled and GameStop is up more than sixfold against indexes that have barely budged. Selling pricey shares beats expensive buybacks, something ViacomCBS used to indulge in, and both companies can afford the share-price declines that came on Tuesday. The media company plans to invest its up to $3 billion of proceeds in streaming, which at least matches one reason the stock has zoomed upward. Reddit star GameStop, which said it would invest any proceeds in e-commerce, is a different case. True, its fourth-quarter online revenue surged 175% year-on-year, but overall quarterly sales fell 3% to $2.1 billion. Social-media love doesn’t make the investment case any stronger.
