Typically, EV’s portfolio and asset returns are updated quarterly to reflect the latest economic scenarios best. In addition, however, an updated set of portfolios and returns would be created when a significant event occurs, e.g. a stock market crash or a key political vote (such as leaving the European Union).
If the event were relatively close to quarter-end, then no change in process would occur. However, if the event happened towards the start of the quarter, an update would be conducted as a special event, and our tools would be updated within two weeks.
