$0.05 for 10K shares would be $500. If you have enough margin, you can short and buy back (or buy and sell if price increases) at the same day, and you do not need any cash for transactions. The settlement will be in 3 days, and you just collect profit at the settlement day if you are lucky. This is what DTs do everyday. However, if you are wrong, you pay the result. Good luck! |
