Yesterday, there was a massive sell-off, which left Google (GOOGL 0.54%) looking like an attractive buy. As far as tech stocks go, Google is on the rise. Even with competitors such as Apple (AAPL 0.53%), Google has still managed to grow its top line by 20%. Google has invested heavily into mobile now, which is grossing an $8 billion business. Now that it has a $200 billion  market cap, Google is in the resounding buy category.
