Google (NASDAQ:GOOGL) announced some impressive fourth-quarter results on Jan. 30. Since the results were announced, the stock has gained 6%. As of market close on Friday, the stock was trading just short of its all-time high. Even more, the stock is up a whopping 52% in the past 12 months. Have Google's recent gains erased any buying opportunity for investors?

In the following video, Fool contributor Daniel Sparks and Motley Fool technology bureau chief Evan Niu take a closer look at Google stock and how investors should think about the valuation today. While he acknowledges that the business is performing exceptionally and that it may even have another lever of growth to tap into by beefing up its mobile ads to levels that rival Facebook, he thinks much of this growth is already priced into this stock.

Check out the video to see whether Daniel thinks Google is a buy, sell, or hold.
