By Michael Gable The Aussie market has pushed past that key 7400 level and clearly remains in an uptrend for now. Today's research has identified a buying opportunity with a chart on Commonwealth Bank ((CBA)). Our prior CBA comment was on 13 April when it was trading near $87. We noted the formation of the ascending triangle and commented that "as soon as we get a break above the horizontal line (if we get a break), CBA shares would then likely make a run higher and attempt to test the $100 level." After making that run to over $105, CBA suffered a couple of large days down on high volume. This put an end to the uptrend momentarily.
