Stock price when the opinion was issued
If you want to speculate on oil, is this a good vehicle? Very, very risky.
One good thing about being in the stock market is that if you don't get it right, right away, over the long term you tend to get bailed out. Products like this have serious tracking errors. You have to be very careful. Only for very short term. He wouldn't use it. The oil price is manipulated.
Lots of oil stocks are pretty cheap, pay nice dividends, have good shareholder returns. That's what he'd do. It's more boring, but less risky.
