CBOE Volatility Index (.VIX) is up .19 to 19.69 despite a 6.5-point gain in the S&P 500, as investors brace for a busy week of economic news — including ISM and construction spending in about 7 min. and monthly jobs Friday. In the options market, one player seems to be bracing for volatility in the VIX and bought the Mar 20 staddle at $2.50, 25000X in early trading Monday. It might close an existing position because open interest is sufficient to cover in both contracts.
