Moments ago the USD value basket - the DXY - rose to highs not seen since July 2010. The recent 6.6% swing is at an annualized 25% rate of appreciation. The dollar appears to have now become the flight-to-safety currency, which historically has been associated with plunging risk values. However, now that the dollar strength is simply a function of other central banks perceived as diluting their currencies more, and injecting capital flows into the G-0 system, all of which is expected to sooner or later make its way to US stocks, this is paradoxically, now a risk on factor. For US companies that have to export into such an environment, this may not be quite risk on, but that is something one can roundly ignore for now.
