CoreLogic (CLGX) broke out of a cup-with-handle base Thursday, but left investors with reasons to be wary. First, the breakout lacked volume. A valid breakout should be accompanied with volume 40% or more above average. Second, the handle in the base wedged upward, meaning the lows trended upward. That doesn’t provide the kind of final shakeout of weak holders that a valid handle should provide and is considered a flaw.
