A fundamental risk management technique is to measure the P&L impact on a portfolio of changes to market conditions. The Hanweck Stress Test module offers you the ability to see how changes in price, volatility and the passage of time will affect all securities in a portfolio – in real-time.
Stress Tests are a natural extension of the Hanweck Options Analytics' Scenario Analytics data feed. The complex computations are performed in the generation of the per-security P&L vector – it is simply the application of the customer’s proprietary position information.
Similar to the Hanweck Options Analytics' Scenario Analytics content, the Stress Test module generates P&L vectors for each position in a portfolio – these vectors can then be used to aggregate across positions, analyze worst-case scenarios, as well as compute expected shortfall and tail risk.
Knowing how a portfolio would behave during the recurrence of a significant historical event can provide valuable insight into the inherent risks. If we were to witness a stock market crash of the magnitude of the Crash of 1987, how would your portfolio fare? The Hanweck Stress Test module can help answer that question.
