NEW YORK ( TheStreet) -- Google ( GOOG) seems to be one of the giants in the social-media stock sector and is surely one of the stocks most followed by analysts. That attention has been a blessing as well as a curse. The challenge of investing in Google is not trying to project the stock's numbers, but trying to determine just how far over or under the real numbers will be from analysts' projections and investors' expectations. In the third quarter, the market overestimated and was disappointed; in the fourth quarter, it underestimated and was surprised. The stock-price acted accordingly -- each time, it pulled back to almost mirror the market. In the above graph, provided by Barchart, notice how in September and January the stock over-reacted prior to financial results being released when compared to my market proxy, the Value Line Arithmetic Index. Let's take our own look at the numbers and plan how to play this stock. (Technical indicators provided by Barchart.)

They also estimate that earnings will be up 14.80% this year, 17.50% next year and continue to increase annually by 14.19% a year for the next five years.
