Monday Morning Outlook: How to Handle a Spiking VIX

Volatility surged last week as stocks took a turn for the worse

...Foreword: There was finally some volatility in the market last week. The S&P 500 Index (SPX) was down 2% on Tuesday, and then fell some more on Wednesday. Over those two days, the index fell a total of 2.6% -- which is its biggest short-term loss since last August.
