There are quite frequently selling stockholders in addition to the company and the managing underwriter frequently works with a "Green Shoe" which is a form of over allotment which allows that syndicate manager to short stock against the box -- the box being the option he has to cover by buying additional stock from the company. It is that short position that allows him to support the market when an IPO gets off to a shaky start. Instead of exercising his option to buy additional shares from the company he executes in the market thereby bringing in buying power and covering his short; the cover is frequently at or a touch below the initial offering price.
Quote from Bob111:
THERE IS NO SELLERS,NO SHORT SELLERS EITHER at initial offering. they can't exist at that time.t.the company give you piece of paper in exchange to your money.
