RE:RE:RE:RE:RE:Next stop $20. Timing is everything with this one. If you bought when S&P was 2090 in August, you could have made 300 %. That is rare of course, and you are right that you will likely lose with this (I sure have, only week I didn't have any was Aug 19). When VIX drops below 16, your odds improve greatly. Best time is when VIX drops below 12. You can't hold this though, as the contract renweal will eat your money at ~ 10 - 20 % per month.
The reason I own this is investing is dead and it has all been turned into a casino. Smart thing would have been take all moeny out of market, but I have only recently learned hits.
