Forex news for US trading on Nov 12, 2015:

The USD-stock market correlation was higher than ever Thursday. It was a tick for tick trade in the US dollar and stock markets today.

It hit a crescendo at the end of the day as the S&P 500 fell 29 points to 2046 to end the day and the euro blasted to a session high at 1.0830.

It's all about investment flows at the moment. The US is by far the best market in the developed world for growth and the money is flooding in. Occasionally, there are jitters in stocks and corporate bonds and the money gets skittish.

What set it off today? That's a tough call. There wasn't anything particularly notable from the 5 Fed speakers today (Fischer still to come). But they were inconsistent and that creates a bit of uncertainty.

Tomorrow is the retail sales report so there could be some jitters.

But for the most part it's just the ebb and flow of an inefficient market that's doing its best. Oil stocks took a hit and then the selling took hold.
