The VIX, as the Chicago Board Options Exchange Volatility Index is known, rose 8.6 percent to 18.14 at 2:19 p.m. in New York, its highest level in a month. The VIX measures the cost of options on the Standard & Poor’s 500 Index, which has fallen four straight days, retreating 0.9 percent today to 1,385.47.
