Middy, to elaborate on what you said. Professional Gamblers try to beat casinos by outwitting them at their own game. The casinos believe that each game has a vig to compensate the casino for being the house. The vig on the games vary but there is always some vig. A sharp gambler knows enough to look for a very low vig in a game that has "bonuses" to overcome the cost of the vig. Whenever the house offers these bonuses the gambler will play because now he has the advantage. If there is no bonus, the sharp gambler will not play.
Professional stock investors do the same thing, trying to outsmart the market. This is easier to do when the vig is low like on stocks on the major exchanges. (less than 1%) However, on the pink sheets when the spread between the bid and ask is 20%+ it is IMPOSSIBLE to overcome such a huge big by the "house". An example of this would be ERHC where the bid is 10 milrays and the ask is 12 milrays. One would start off 20% in the hole buying at this spread. So the share price would have to go up 20% just to break even. Making any money under these circumstances in virtually impossible in the short term, so day trading stocks like ERHC is a no win situation, because of the high bid/ask spread. Anyone that says they can do so is not being truthful.
