Really, we've had some focus (on oil) since mid-February, when both markets made a significant low, and both markets had a near retest of those lows on Wednesday. Oil is emerging as the focus for the gold market as a surrogate for general commodity inflation. Without that kind of commodity inflation, then gold becomes a less attractive investment.
The oil companies themselves aren't interested in building new refineries and will tend to denigrate the chances of any new investors actually succeeding in their business. They'll say, 'What does Richard Branson know about oil refineries' He doesn't have to know about that part of the business, but he can easily see that oil refiners are making a margin far superior to what he's making in the airline business.
