Id like to continue having the flexibility of trading the leveraged and inverse ETFs. They not only provide me with enhanced return but also help me to hedge my portfolio as I am not able to buy options (puts) per our companys trading policy. I have a good understanding of these ETFs and happy to have them as part of my risk management tools.
