FX:USDOLLAR Dollar Index
Both the Dollar and S&P 500 advanced through the past few years. The positive relationship is fundamentally atypical for a safe haven like the USDollar and speculative benchmark like the index. That positive relationship has come under moderate 'risk' appetite that kept rising under on moral hazard while the Greenback climbed on shifting forecasts. That positive relationship may carry through should the recent S&P 500 drop deepen.
