Whatever investors are worried about right now, those concerns are not showing up in Wall Street’s fear gauge. The CBOE Volatility Index (^VIX), or VIX, closed on Friday at 11.36, its lowest level since March 2013. With the typically slow summer months just ahead and little on the horizon to shake the market from its current course, investors could be looking at even lower VIX levels, some analysts said. The S&P 500’s record high and the drop in the VIX are not the only signs that fear is not a factor on Wall Street.
