Steven Sosnick on investors piling into Apple and Microsoft

The one thing that does worry me is the concentration in everybody's favorite stocks, so to speak.  You've got now Apple and Microsoft combining to be 25% of the Nasdaq 100.  Stop and let that sink in: two stocks being 25% of a major index.  They're 13% of the S&P 500, give or take, combined.
