In a year in which stock prices mostly have been driven by news rather than fundamentals, three things stood out last week. First, terrorism has taken on an unsettling new face -- the stay-at-home mom down the street or your long-time co-worker at the plant -- as the dark side of the exponential growth in social media rears its ugly head (with something much more sinister than porn sites or online bullying).

But the technical damage to the charts is severe, particularly to the small caps, which are in full-blown correction mode. The large caps must show leadership and rally immediately -- or it will put at risk the critical and widely-anticipated year-end rally.
