At all time highs AND at resistance

Yes, 'tis possible. And when one is able to discern trends, oscillations are no longer random. See, for example, the trend line of resistance (now, at ~$234) delineated in the chart (below) of Google/GOOG...

Please do not misunderstand this trend line, nor me. If this trend line continues to prove valid, I expect it merely to restrain GOOG's upside, if it does even that. It could even allow GOOG to 'fill the chart' with a base or other consolidation/congestion type of pattern. I do not expect the shares to turn down suddenly, materially. In fact, contrary to the claims of the bears (who are really getting it handed to them) there is nary a sign of a reversal anywhere to be found. And how sad it is for them: to be on the wrong side of such a historic opportunity.
