A savvy investor would wait for the market to cool off in a bit and buy at a much lower price. We haven't seen $600/share since March, but if you see how these things operate over a duration you will see that after most spikes there is a pull back. Wait for the pull back.

EDIT: Also, options expire tomorrow (3rd Friday of every month), so there is ample manipulation opportunity.You can get an idea of what's going on in the options market here:

I would agree with this. Google is up over $100 since G+ came out, so I think there will be some people eager to sell tomorrow to cash in on the strong uptick.

Taking a further look: while just looking at the most popular options' strike prices, there are 10,141 put options at a strike price of $500/share, and there are 7,736 call options at a strike price of $550/share. I find looking at the spread with all the details interesting. I suspect most of the people modeling this are paid to keep it proprietary. I wish I had the talent, because it could probably start a fascinating discussion on a site like this.

EDIT: put option numbers were incorrect. Time stamp is ~6:30 PM EST.
