Can I open long and short positions, and then just collect the dividends on my long position?
You can't have be long and short the same stock in the same account at the same time. The positions will cancel each other out.
If you are long the stock, it is not possible to sell the stock short. The broker will sell the stock that you own. If you are short the stock, and you place an order to buy, that order will either be rejected, or it will be treated as a "buy to cover" order.
I understand ill get paid dividends for my short position too, but Ill have to pay those to the person I borrowed the shares from
You will
not "get paid dividends for your short position."
When you are short stock, you don't collect dividends. But you still have to
pay the dividend out of your own pocket.
Why? Because you only
borrowed the stock in order to sell it. You don't own it.
The company will pay only one dividend: to the guy who bought the stock
from you, after you borrowed it and sold it short.
You don't get a dividend, 'cause you don't own the stock. But guess who also expects to get a dividend?
The guy you borrowed the stock from. He still owns it, and he wants his dividend.
Guess who has to pay that dividend?
You could be long the stock in one account and short the stock in a different account, and it's still going to come out as a wash. You would collect a dividend in one account, and have to pay it in the other account.
