Naked shorting is illegal and I doubt very much that any reputable broker would allow it. Market makers have an exemption from the rule, which allows them to maintain a liquid market. (That's their purpose in life, after all.) If mms weren't allowed to go naked short, there would be plenty of occasions when you wanted to buy, but the mm had no shares to sell you and the trade couldn't be completed. The only ways a mm can go naked short is by selling to another mm (so the net total mm position stays the same) or by you and me buying. Except by trading with another mm, there's no way he can initiate a naked short. He might intentionally build a naked short position by playing around with his prices, but unless he knew for certain that he could close the position out at a lower price (by doing a deal with a company about to do a low-priced placing, for example) he would be running the risk that he will be short in a rising market. Once again, most mms don't really care where the sp is - they make their money on the spread between their bid and their ask whether the sp is rising, falling or standing still. Although I'm told some mm firms have an active trading division that do take positions, a straight mm wants to keep his position, whether long or short, as low as possible most of the time. It's the trading volume that means profit, while sp movement can often mean loss.
