NEW YORK (Reuters) -Options traders are pricing in about a $260 billion swing in Nvidia’s market value following the chipmaker’s second-quarter earnings expected on Wednesday, U.S. options market data showed. Nvidia options implied a roughly 6% swing for the shares in either direction following the results, which will be reported after markets close on Wednesday, according to the data. That is below the 7% long-term average move, suggesting that investors may now have a better handle on what to expect as the company matures.
