Market makers provide liquidity. Contrary to what you read on the Yahoo message boards, they don't purposely "take out" stops. The stock market is a virtual auction, made up of buyers and sellers. DECK is declining now, because there are more sellers than buyers.
Do you see why you can't rely on a stock that closes at the high of the day (yesterday) to be guaranteed to rise the next day? There's much more at stake here, including the fact that DECK is in a confirmed downtrend, even though it traded countertrend the past several sessions with the market. That said, it's still early, and anything can happen.
Okay, I'll let you be naive. But just to ask you a question; how is it that Goldman Sachs makes the most of its money?
I'll save you some time and answer the question; MARKET MAKING!
They are all thieves. Market Makers make money off spreads and front running. It is not a BIG SECRET. It is outright manipulation and the SEC is a joke. The fox is in the henhouse. It is not hard to see. Long term, BIG MONEY like Goldman Sachs buying in the low 30's pushes a stock higher over time, but in the short term, meaning hour to hour, day to day, MM's definitely doing things nobody else can and making money from it.
A great trading stock. In at just below 50 over the last couple of weeks, out yesterday at 53.59 for a quick $3500. Will buy back at 50 to 51sh and do it all again. Done this all year, rarely a losing trade.
