Big Cap Rally @ New Record Highs; why NOT the Russell 2000 et al......?

Russell 2000 ($RUT) Daily Chart @ Close 08/25/2014

The headline grabbing DOW & S&P500 may be leading the 'charge' higher on Central Bank 'largesse' globally; a peek below the 'hood' of THAT which employs more people than the Big Cap stocks........and it's NOT so bright a story.
Losses since July yet to be retraced beyond 62% & THAT leaves the health/ sustainability of the S&P500's advance rather questionable?
