Shorting all ULTRA etf's is stupid
It has been shown that shorting all leveraged etf's will over the long term provide you with a positive score and accuracy points for all picks. It is not however the best way to use those tickers within CAPS.
Instead, if you think the SP 500 or a sector will go down short the ultralongs. If you think the sp 500 or a sector will go up short the ultrashorts.
At least attempt to demonstrate some market timing ability. If you get it wrong at least you pick will turn green at some point in the future.
