My good man - specialists can only take offers to liquidate positions not INITIATE positions. This does not mean that once a stock is trading at the offer price the specialist can take an offer, unless he is liquidating a position.
Rule 104 - Dealings by Specialists
(A) The specialist may liquidate a position by selling stock on a direct minus tick or by purchasing stock on a direct plus tick only if such transactions are reasonably necessary in relation to the specialist's overall position in the stocks in which he is registered; and the specialist has obtained the prior approval of a Floor Official;
Trade_Cents,
That doesn't mean the specialist can't participate in the offer. He can take up to 1/2 the offer size once it is "tripped," subject to few restrictions.
Rule 104 (b):
...the purchasing of stock on a direct plus tick or a zero plus tick should be effected in conjunction with the specialist's re-entry in the market on the opposite side of the market from the liquidating transaction where the imbalance of supply and demand indicates that immediately succeeding transactions may result in...a higher price (following the specialist's purchase of stock on a direct plus tick or a zero plus tick).
Translation: The specialist can "reload" at the bottom to provide liquidity for the ensuing rebound.
Specialist do this routinely and make a lot of money from it.
