Looking to put in a little cash into oil and gas. Been hearing about the rise of gas and how it’s gonna start up again, so I figure get in before it’s jumped. Just curious if y’all think an etf such as $Invesco Dynamic Energy Exploration & Production ETF(PXE.US)$ , $iShares安硕美国油气勘探与生产ETF(IEO.US)$ or $第一信托ISE-Revere天然气指数基金(FCG.US)$ are preferred over something like $英国石油(BP.US)$ or $雪佛龙(CVX.US)$ . Thanks in advance!
