kotek01, I very much doubt it has anything to do with manipulation.
Much more likely is that they are programmed trades by one of several brokers who run computerised programs. I've seen it in a number of stocks, how they can ever make a $ out of these tiny trades beats me, RDF has long been subject to this but usually the trades are in the low hundreds, 112, 224, 160, etc, oddball amounts like that.
My guess is that they try to beat the odds by selling at the average high so far that day and buying at the average low. Sounds crazy, anyone else with a better idea of how it works?
