Stress testing a portfolio
Stress testing is a computer simulation technique used to test the resilience of an investment portfolio against possible future financial situations. By simulating a drop in the market, you can see by how much your portfolio may lose value. You can also take the beta of securities in your portfolio into account, to provide a potentially more accurate picture of how your portfolio may react to the change in the market.
- To stress a portfolio, check the Stress toolbar check box.
- The Stress Portfolio window appears.
- Move the slider to select the percentage by which to stress the portfolio. To simulate a market drop, move the slider to the left. To simulate a market rise, move the slider to the right. To clear the existing stress, click Clear.
- To provide a potentially more accurate picture of how the portfolio will react, check the box Use beta to compute stressed prices. Beta is a measure of a stock's volatility in relation to the overall market. By definition, the market, such as the S&P 500 Index, has a beta of 1.0, and individual stocks are ranked according to how much they deviate from the market. When you check this box, TakeStock 2 will use each security's beta to compute the effect of the stress on that security.
- To automatically switch to the "Current market value (stressed)" view after stressing the portfolio, check the box Automatically switch to stressed positions view.
- Click OK to apply the selected stress.
- The portfolio reflects the applied stress.
- Click the stress value text "-15% (β used)" to change the amount of stress you want to apply.
- Check the Stress box to alternate between a stressed and unstressed view of the portfolio.
