Last night Google shares (GOOG) dropped from $548.59 per share to $502.47 a share, a drop valued at around $13 billion in total value. $13 Billion is enough to buy some very big companies. It’s a shame to see this happen, but, it’s also good to see that Google isn’t perfect. At least this will encourage some competition to jump in while Google is down. Interestingly enough, Google stock opened this morning at $511.90, up a bit from the low $502 early morning and late last night.

It’s safe to say that if Google goes back over $548.59 that anybody who gets in now is bound to make some cash. The only problem is that with a drop of $13 billion, a lot of people are going to be hesitant to jump on board right away. Google has been purchasing several companies lately including Doubleclick, which has earned them a court date in Washington. On top of that, several Google AdSense publishers have reported that their AdSense checks have been bouncing lately. I don’t know what would have caused that, but, I doubt Google is going out of business anytime soon. At the very least their stock value is simply balancing itself out. A lot of people have considered it to be very saturated over the past few years. It seems that every once in a while it takes a drop like this. So far it has managed to rebound each time.
