We had a pretty decent pull-back in spot gold, so I think there is some profit-taking here.

The pullback in crude is mostly related to the tentative deal between Russia and Iran on uranium enrichment, and gold is softer mostly for the same reason.

There's been a lot of selling and profit taking — across all asset classes, actually. Oil is weaker, gold, silver, platinum and palladium are weaker, and base metals are weaker. It's just fed on itself.

It's pretty much from experience. You learn from experience. And you make mistakes ... of course you make mistakes, you know. But you learn from them, and you go forward, and you won't make the same mistakes twice, hopefully, you know.

The firmer tone for crude futures should underpin the market at the open.

The surprise fall in crude stocks has helped the rally and the energy sector has keyed off that.
