Looking at a weekly chart for a more smooth trend view, we can notice that in recent weeks Google has been trading inside of a range (620-700, roughly). For now, it is still inside of the range, but it is on the higher end of the range. With earnings coming up, I believe that Google will close above 700 for the first time prior to the report, and a large upside breakout of the current range. I think it can rally as high as 780 or even briefly touch 800. There has been a large accumulation (sideways trading/consolidation) since they announced the split and prior to Q2 15 earnings report. Recent analyst ratings show that the company still has more room to go, with some analyst price targets as high as 850.
