Nasdaq's Kevin Davitt turns to historic data in the index on Fed days and why Wednesday's "kneejerk" downside reaction to an interest rate hike can reverse in sessions ahead. While realized volatility in Nasdaq-100 (NDX) options remain low now, Kevin points to catalysts ahead that he expects to change that outlook. He then examines heightening dispersion between the iShares Expanded Tech-Software Sector ETF (IGV) and the PHLX Semiconductor Index (SOX) to explain how it adds onto lingering Nasdaq volatility.
