Quote from optionsgirl:
So how does a market maker hedge differently than what a retail trader can do? Like it is indicated before, I suppose because of lower hedging costs, this is how a market maker can make money and not just because of the bid/ask spread.
I read somewhere that about 90 percent of market makers make money and 90 percent of retail traders lose money. Ignoring the exactness of the numbers, I assume this is one of the reasons why people accuse market makers of manipulation and ripping off retail traders...
Regarding market manipulation, you usually hear about short manipulation. What about long manipulation? Is it harder to manipulate a market upwards? I mean I am not looking to manipulate the market with my puny resources, but I would like to know how I am thrashed about by this.
The Market Maker's Edge by Josh Lukeman. I read in an amazon review that this book didn't really talk much about market making techniques, but then again, sometimes amazon reviews are untrustworthy.
