In browsing finance websites Monday, investors may have mistakenly thought they'd gained millions or billions of dollars—or lost as much. In reality, Google Finance, Yahoo Finance, CNNMoney, and Bloomberg mistakenly reported Monday that share prices for a variety of companies were exactly the same: $123.47, reports CNNMoney. That suggested Apple and Amazon stock had suddenly crashed, while Microsoft was up 79%, eBay was up 254%, Mattel was up 473%, and video game developer Zynga was up a whopping 3,292%, per MarketWatch. Nasdaq explains the sites shared incorrect data sent out as part of "normal evening test procedures," adding that no trades were affected. (More stock market stories.)
