Yes, this is done by hedge fund operator every day. And NO, this is not market manipulation, assuming the buyer did not have access to confidential inside information. That's because there is no guarantee that the price will move up on his purchase, even though it likely will if it is a stock which generally has a lower daily volume.

False. Every trade determines the price of that trade. If the price were artificially inflated to $10.50 by the buyer and should only be $10, who would be the buying party who would buy it at the higher price? While supply and demand is one factor that determines share price, there must be a buyer and seller who agree on a price for a trade to happen.

Your sale may cause the price to fall even more before you can get out.

If a person buys 1 million shares of ao

company at 10 dlls, and that causes the share price to rise to 10.50 dlls and then sell them and earn 50 cents per share, it's considered manipulation?

I have read that this is done every day in the market
