That might be true, I didn't check, but the ups and downs of the stock matter a lot to your broker when you're using margin. Let's say you use your own $100 and borrow another $50 and buy $150 worth of this stock. If the stock drops 66%, your $150 investment is now worth $50 and you owe that entire $50 to your broker (they would have sold you out with a margin call somewhat before this). You will be wiped out and lose everything if this stock drops by 2/3 at your suggested level of margin. This isn't hypothetical - this actually happened in 2008-2009 less than 8 years ago. Do you want to bet your entire $1M that it doesn't happen again, ever?
Good luck with your choice and be careful.
