i think it was normal, actually more than half of that 80k should be from MM, the rest is from the weak hands, who want the profit so bad. i can't see why it's illegal--we have a 100% free market, dont we, then MM is also one of the participants, they can sell/buy in what ever price they want to right?
you said "low price", actually there is no low or high price, market is changing in uncertainty, you view it as low, maybe someone else think that's good price to sell, that's basically how the market works.
bigbrother, You would be right if the price was determined strictly on supply and demand. But the MM is in control and he can drop the price in a flash of an eye. Naturally, some traders then sell to try and lock in some of their profits causing it to drop further. You can spot these walk downs when you see the price drop 10% on a few hundred shares, but it takes thousands of shares purchased to raise the price.
The market maker knew that he was going to have demand for this stock today, so he walked it down to scare people into selling and pick up cheap shares that he knew that he could sell later in the day for a big profit. Is this leagle? If it is, it shouldn't be. But that is how the NAZ works.
