most investors can't short pennies but MM's have no problem doing it. Hope you noticed who has been playing bid and ask lately and the spread.
Copy and paisted from investors web site:
There are a few things that you need to know about the market maker NITE. Knight Securities uses the ticker $NITE. This market maker is known for being one of the most abusive market makers in the penny stock market. Most of the popular penny stock brokers route from NITE because they are quick to execute most orders. One thing that I’ve noticed is that NITE tries to screw you over. You have to realize that each market maker has it’s own complex algorithm that tries to make them money. Sometimes they make money by shorting the ask and then covering on the bid. Sometimes when a stock is running and you place an order on the ask and you don’t get filled, it is actually the market maker taking shares on the ask.
