the weekly chart below denotes a 'bullish' consolidation phase by way of a 'flag' pattern. the way these things work is that I buy them at a breakout out of the trading range on good volume.
the much juicier trade however is if this bullish setup fails and prices break below the trading range. I am watching this stock for now, not trading it yet. A break below 126 or above $143 would get my attention though.
