We talk about it. Right now there is no stock to talk about - but we still talk about it.
There is certainly room for concern. When everyone and there mother wants in on something - that is generally a poor time to be in on it.
I did that when netscape went public. I was sure they were going to bomb. Shorted it in online stock game. No way they were worth that much - and just got my goat as they went higher and higher.
Google will need to maintain massive growth to be able to support what is almost certainly going to be an inflated stock price. Can this bubble outrun the markets pin and last until google gets up to a reasonable growth level to support such a price?
I don't know. Neither does anyone else. Nothing like this has happened before - unless you want to go back to tulips. Not exactly what I had in mind anyway.
Speaking of adwords - when we find out the growth figures of profits - I would encourage everyone to throw out any data post 11/15. Look at the growth before that - then extrapolate from there.
I guess some are wondering if they can get in at IPO price and sell and make some cash the day it goes public. Possibly. Google has every reason to try and get every dollar they can out of the public. This won't be going for bargin prices.
No matter what price it goes for - people are gambling in taking this strategy - they are not "investing". The gamble may pay off.
After they go public - every rumor and analyst upgrade and downgrade will likely have a fair impact on stock price. The opening day after day 1 will almost certainly not be within 5% of closing price on day 1. People will either panic one way or another "Oh My God - what did I do" or "Oh My God - I should have mortgaged the house". Only time will tell.
Earnings growth seems to drive stock prices. Unless Google can continue theirs - it is unlikely the stock will have any real upward momentum for any long period of time. Nothing that would justify the risk of concentration into one stock versus a basket of diversified investments.
Remember - as most on here already know - Google owns (or at least did for the time period we will se figures for if the go public in April) the majority of search traffic. It is hard to imagine them ever having the monopoly on traffic as they do now. They can grow as the admarket grows, as the internet population grows, as they cut costs, and so forth, but their core growth phase - the one the most engines stive for is over.
