Short sellers have every reason to feel that the market deck is stacked against them. When company stock shares go through the roof for no apparent reason (.com companies with no value, solar energy stock quardupling over a year with no products to market, etc), no one stops that. It's "normal market forces" speculating on future value (cough). Where is the government handouts to the shorts that are losing when the market gets out of whack to the upside?
So when companies finally have their hat handed to them and longs are screaming uncle, the government comes in and bails everyone out. All they get is a firm wag of the finger and short sellers are shafted.
Again, I don't short sell for a number of reasons, and this is a good one unfolding right before us. I don't usually make any recommendations on this blog, but I will here ... do not short sell stocks for the long term. If you must do some short term speculation to the downside or hedge an existing bet, please consider doing so with options. Short selling is no way to make money long term.
