It's hard to say at this point on PBR. The stock is below all sorts of resistance. The real sell should've been yesterday, at the open, when the stock opened below previous support, at 42.50. If I were in the stock now, though, I'd set a stop-loss at $39.95. If that level gets breached, then, take the hit -- unless you're comfortable holding until 37.50 (the next support level).
