Yup and in my book that is a great trading/position strategy to play in these type of O&G...I have successfully utilized this strategy with HMGP and NVMG..... you are protecting futures profits and or allowing yourself to build a larger position. IMO that is very constructive.
Also the strategy on selling back your initial investment after a triple % move "get your seed money back" is also a nice way to go.....nothing wrong with free shares.
