I think enough time has been spent on the 1% maximum downward price movement interim rule.I think we should start discussing the yet to be implemented initiatives especially the "market makers" and the "share buy back" initiatives,send in data from different sources and discuss their possible impact on the market both in the immediate and long-term before guidlines for their implementation are announced.These are some things i have on market makers(sources not included,however)-i think they should set the ball rolling on this subject-
The market maker assures that there will be a market for the security; however, they don’t guarantee it will be at the price you want.
Market-makers generally must be ready to buy and sell at least 100 shares of a stock they make a market in. As a result, a large order from an investor may have to be filled by a number of market-makers at potentially different prices.
Market Maker Revenues and Stock Market Liquidity
We use an 11-year panel of daily specialist revenues on individual NYSE stocks to explore the relationship between market-maker revenues and liquidity. If market makers suffer substantial trading losses, lenders may respond by increasing funding costs or reducing credit lines, and market makers should respond by reducing liquidity provision. The data indicate that when specialists in aggregate lose money on their inventories, market-wide effective spreads widen in the days or weeks that follow, even after controlling for stock returns, volatility, and volume. This suggests an important role for market-maker financial performance in explaining liquidity time-variation. Revenues at the specialist firm level explain liquidity changes in that firm's assigned stocks. Revenues at the individual stock level do not explain changes in individual stock liquidity, consistent with a financial constraints model with broadly diversified intermediaries. Aggregate specialist revenues are increasing in conditional return volatility, as is revenue volatility. Specialist margins (specialist revenue per dollar of trading volume) are essentially constant across stocks, implying limited scope for cross-subsidization.
market maker
Definition
A brokerage or bank that maintains a firm bid and ask price in a given security by standing ready, willing, and able to buy or sell at publicly quoted prices (called making a market). These firms display bid and offer prices for specific numbers of specific securities, and if these prices are met, they will immediately buy for or sell from their own accounts. Market makers are very important for maintaining liquidity and efficiencyfor the particular securities that they make markets in. At most firms, there is a strict separation of the market-making side and the brokerage side, since otherwise there might be an incentive for brokers to recommend securities simply because the firm makes a market in that security.

How can "Market Makers" operate under the (1%) minimum loss and (5%) maximum gain environment which is very contrary to the way they operate?
