Meanwhile, it did show some deceleration in revenue growth -- something that has become apparent over the past two quarters. Its net revenue has shown a noticeable decline from 27.7% in Q4 2011 to 24.4% in Q1 2012. So investors would be wise to keep an eye on that area. Moreover, while it has done an excellent job managing a reduction in ad revenue, it has yet to provide additional details regarding its strategy in terms of its acquisition of Motorola ( MMI). From an investment perspective, I maintain that Google is one of those stocks that is a buy at any level. At its current level of $576, the stock is down 14% from its 52-week high of $670. I would be adding shares at current levels and buying more on any signs of weakness. The stock should easily cross the $600 mark before the end of the third-quarter on its way to at least one more 52-week high before the end of the year.
