If you even understood how it is done, you would not be able to do it on a penny stock. ASK YOUR FUCKING BROKER IF YOU CAN SHORT PENNY STOCKS!!
Shorting 10,000 shares of NSAV would cost you $25000 in margin, if it was permitted. That is $25K you 'give' to your broker to hold to cover any loss. You get it back when you cover, if you 'win' the short. But with a stock rising quickly, why would anyone bet that it would go down? Or even better, why would they bet $25K that it would go down.
Nice try, Alice, but all you have shown is that you are ignorant and tossing around words you hear from 'real' traders without knowing what they mean. But that's fine, I put ignorant asses on ignore anyway...buh-bye...
