+ your own wordsQuote from SteveD:
Their stock is restricted as to when they can sell. If it is a "dog" stock could be at $10/when lockup period expires.
Don't understand what you mean by "dumped". There are no extra shares just laying around, LOL. All shares are very definitely accounted and sold to someone at the offering price of $27/share.
I suggest you get a prospectus and read it over very carefully and it will help you understand the process better.
Good luck

And, remember, the MM also has a lot of inventory of IPO's that dropped from the first day. Very few like BIDU.
my words-any excess or unwanted inventory is dumped in normal MM operations."
i suggest that you read up on marketmaking. it will prove helpful.
i will read an ipo prospectus to review how overallotments are handled and market stabilization is handled.
good luck.
