Pseudo history in VaR modeling is about reconstructing hypothetical portfolio returns using current positions combined with historical market movements. Rather than using actual historical P&L, which reflects old positions that may no longer be relevant, pseudo history applies historical market changes to your current portfolio holdings. This tells you how your portfolio as it exists today would have performed during past market conditions. For example, if you currently hold €10 million in EUR/USD but historically only held €5 million, the pseudo history will show twice the impact of historical FX moves compared to your actual historical P&L. This makes the VaR estimate more relevant for current risk management since it reflects your current exposures and trading activity rather than past positions that may no longer exist in your portfolio.

A is incorrect. While backtesting is important, "pseudo history" is about capturing the impact of position changes, not just historical market events.

C is incorrect. While "pseudo history" uses historical data, its purpose is not to predict future portfolio losses. Instead, it evaluates how the current portfolio would have performed under historical market conditions. Predicting future losses involves forward-looking stress tests or scenario analysis, not pseudo history.

D is incorrect. Pseudo history involves combining actual historical market data with current portfolio positions, not generating synthetic data. Synthetic data typically refers to artificially created data, which is not the goal of pseudo history.
