S&P 500 up just 5 points

Biotech stocks are under pressure and the Nasdaq has fallen into negative territory. The S&P 500 is up just 5 points to 1963 after rising as high as 1979.

One of the catalysts was a tweet from US Presidential candidate Hilary Clinton lamented price gouging in pharma and said tomorrow she will outline a plan "to take it on."

The negative correlation with EUR/USD and stocks is rocky at best. We don't need to look beyond Friday for an example as stocks tumbled and so did the euro. However, in general the euro has tended to strengthen on soft stock markets.
