Three offensive sectors closed above Oct. high: XLI, XLK, and XLY. Consider them as lead sectors. All of them, as well as $SPX, are above strong short term up trend line. It's dangerous to short the market before all of them break down their up trend line.
Also, there are three offensive sectors did not fill the gap: XLF, XLI, and XLB. As said, XLI is already a lead sector. The rest two show their strength today and may become new leaders.
