Hi Clay, I dunno about the supply thing. Every time I place a market order, and I mean EVERY TIME, I am always getting a price volatility message from my broker. (Etrade) Next time I get it, I will post it. It reads something like this: "Due to unavailability of shares price volatiltiy may ensue". Or words to that effect. Now is this because Etrade doesnt have any?? I doubt that. They simply purchase them.. but if there are none ... well then ....
I was ask slapping in the 1.10 ~ 1.20 zone.
Edit: I slap the ask on a stock that I like hence the market order. LOL
