To put the value of NVIDIA's stock price in perspective, its price is expected to swing at least 8 percent (one way or the other) in response to today's earnings release. Bloomberg writes: "That would equate to close to a $300 billion swing in market value — bigger than all but 25 companies in the S&P 500 Index. And according to strategists at Bank of America, the report carries more risk for the benchmark than the next Federal Reserve meeting or inflation data."
