RE: Silly question...You short NG is you believe price of NG is going to down and to go long on NG means you believe the price of NG will go up. If you think it will go up, buy HNU, and buy HND if you think it will go down.
This is not a very good board for newbies, There are some people on this board who are total douchebags who think they are financial geniuses and act like they are so smart when it comes to buying/selling ETFs. It all comes down to luck and has nothing to do with being smart. We all know know who I am referring too.
