There are two thoughts of play that come after a nice breakout, that depending on your bias you can spin it either way you want. Below is a good example of this with the chart of the XBI. One which I fully endorse is that the best breakouts work right away, and should continue on an upward climb in a rapid fashion. The bearish view on breakouts that stall, are that they are exhibiting signs of exhaustion and a ripe for a fall which could eventually become a bull trap. On the XBI I am a believer that this will break higher, as the ETF has done a three things I like. First it is holding the very round par number with just two CLOSES below the figure since finishing above it on 5/11. Secondly last Friday it bounced firmly off its rising 50 day SMA after its recent break above the double bottom pattern, often a good entry point. Thirdly it is shrugging off bearish candlesticks with engulfing candles on 4/28 and 5/26 and a dark cloud cover on 5/12. On its WEEKLY chart the XBI has the look of a bull flag formation. A break above 108.25 would carry a measured move of about 50 handles higher.
