NEW YORK – Think Dow 11,000 is a big deal? Think again.
The Dow Jones industrial average briefly hit the milestone Friday for the first time in 18 months before closing at 10,997.
But Wall Street analysts who study key stock index levels say all the attention paid to 11,000 is more like a big distraction.

As stocks have risen over the past year, the volume reflects the vulnerability of a rally riding on the shoulders of relatively few participants.
