If you want to do that, you need a lot of money, maybe $1milion? Really, really big you need to influence the price, although in a small percentage.
1 million is chump change for these kinds of moves in my head. I believe you need at least 10 million, if not 100 million with a few other individuals. Then you can really move the needle, whereas 1 million may only cause a small intraday swing.
