Didn’t realize there were carrying costs to cover the short. Makes sense.So normally you buy a stock that you think is going up, and sell it when it hits the target, right? In this case you sell a stock that you think is going down, and buy it when it hits the target. There's no real difference, except when you short a stock you have to pay a cost to borrow the stock to sell to someone else, and that carries a percentage that is typically .30% or so per year, so relatively small. But in the case of a hard to borrow stock, the rates will be much higher, and is usually calculated daily, if you can borrow it at all.
The other factor to consider is risk. If you go long (buy) a stock, you have at risk the entire amount of your purchase, in the case that the stock goes to zero. If you short a stock, you theoretically have unlimited risk to the upside, so you have to do things to mitigate the risk. Your brokerage will require additional margin to cover this, and you may wish to purchase protective options to further mitigate your risk.
Lastly, if the stock is a dividend stock, you'll be responsible for paying any dividends that the stock pays to the buyer. Your broker will debit your account when this time comes, so it pays to remain aware of ex-dividend dates to avoid this happening to you.
Thanks for thorough answer!
