OK, let me correct my statement -- I should've said that market makers might be short or long during the course of the day, either from providing liquidity or trading for their own account (when the firm permits it), but generally they seek to end the day flat every day. The typical refrain "the MMs are loading up!" is nonsense.

Also, generally a MM will short first and cover second, and rarely the reverse. When a MM sells a stock to provide liquidity (as distinguished from selling on behalf of someone who placed a sell order), it's almost always a short sale and he'll go on the bid to cover. That means that the other typical refrain, "the MMs need shares!", can have some truth to it with a rapidly rising stock -- IF the MMs have been selling short to provide liquidity.
