Don't short stocks. Period. The loss potential is unlimited and you will get margin called if it keeps going up.
If you really want to short SPCX, buy puts on the options market. Your max loss is the cost of the put.
Also, if an inverse ETF gets created eventually, don't do that as the child thread suggests. Inverse ETFs have a specific purpose, same as the leveraged ETFs. They are intended for day trading and short term hedging. The ETFs have to settle positions daily so there there isn't a perfect correlation the the actual rise and fall of the underlying security.
Enjoy. I bought 10 lousy shares at trading started. I always kick myself for not being more aggressive, not much of a risk taker. That little trade is up 30% so far, still holding.
