Consequences of buying/selling a large number of shares for a low volume stock?
If you are the only one who puts in a large market buy order, then it would definitely push the price up. How much up would depend on how many would be willing to sell at what price point. It would also be possible that your trade will not get executed as there are no sellers. The same would be true if you put in a large sell order, with no buyers. The price would go down or trade not get executed as there aren't enough buyers.
