Default Re: Difference Between Poker and the Stock Market

[ QUOTE ]
If you send a large market order the the NYSE I guarantee the specialist (head market maker) will fade your bet every time and take the EV between the market equilibrium price and the price you are executed at. This difference is the Market Maker's vig. Examples are best seen in illiquid stocks, as their markets tend to be wider, but they trade smaller volume. The purest form of a market maker makes the bulk of his/her money in the same way that a casino does, by taking many small +EV bets (much like a successful poker player).

What kind of order are you talking about? Anyway what you described here isn't in the least bit similar to what a casino does. Perhaps similar to casino's competing for customers business. In the scenario you describe both sides can be +EV, DUCY? Of course OP was about poker not casino gambling.
