Big players accumulating on the down draft. Happens ALL the time . Look at the 2 year chart and the trend is clear , but it happens in many, many other stocks as well.
flatwood - you bet they are. EXC grossly undervalued here. NG will totally drive the price in the near term. That's what the runup last spring was all about and the next one should carry us comfortably in the mid $4mcf range.
Close below $28.58 is very bearish, no apparent support except through dividend, could easily drop to below $26 pretty fast.
