RE: Anonymous Pros at work. It is very hard for them to buy when prices are moving up and here is why. Psychology plays a large role when working the market. I do know that when share prices continue to rise I tend to hold my shares a little tighter than a flat or downward market. The reason for this is greed. The pro/marketmaker may sell shares back and forth putting downward pressure causing people to put their shares out for sale at maybe a slightly higher price than the market they have created, at which time they will come up and buy whatever is offered, then they will push the market slightly lower again and repeat until they feel they have a position that makes it worth their while. What quite often happens is these same parties will take the sp up by trading shares back and forth eventually selling off there position to unsuspecting investors who are thinking that something big is happening. Eliminate greed and use a little common sense, money can be made investing in the market.
