As the European debt crisis once again makes headlines, with no indications of a quick solution on the horizon, the US equity market has reacted by suffering from a bout of increased volatility. Should there be any doubt as to why, correlation of the S&P 500 to the Euro has been increasing as well. Below, we present a chart showing rolling 90 day realized volatility of the S&500 index (red line) along with rolling 90-day S&P 500 correlation to the Euro currency (blue line).

The system applies user-defined underlier price and implied volatility stresses and re-evaluates positions to determine individual and total P&L impacts. In addition, a very handy feature is the ability to select hypothetical index moves and see how these translate into potential moves in an equity, future, or option position. For example, users can input a hypothetical 3% drop in the S&P 500. The system will translate this into corresponding moves in each option underlier (or direct equity position) and then re-evaluate the entire portfolio based on these moves. The result is a P&L impact identifying whether the portfolio would lose money or not.
