so a hedgefund cant just dump amazon stock like chatrooms do with penny stocks
You need to sit down a look at the basic stats for these companies and do some basic math. Ask yourself:
What would it cost to buy or sell 2x the average daily volume of stock X? What would it cost to buy a 5% ownership stake in the company?
If you can't do that, I suggest you discontinue trading individual stocks immediately.
Also, keep in mind that many of the largest firms are managing other people's money. They are generally constrained by the prospectus for a variety of funds. An SP500 fund might have hundreds of billions of dollars of AUM, but the can't use it all to go buy puts or calls on a given stock. They have to buy a basket of stocks that tracks an index. The set of funds that have many billions of dollars that they can use for short term speculation is going to be rather small.
For market makers it is.
Why wouldnt they pump a stock same way as penny stocks?
This is saying it's as easy to fill a concert venue for 100,000 as it is for 100. It's obviously silly drivel.
Does it really make a difference what you are trading?
Yes. It does.
The entire market is manipulated whats the difference
With that kind of attitude I bet you're killing it.
In some ways manipulation is almost a best case scenario. If an asset is selling for 1/10 or 100x what it should be, those are opportunities. Figure out if you're right and figure out a way to profit.
If you've got real evidence of actual manipulation, call the SEC top line and cash in.
