Formula and Logic
The parametric method uses the formula: VaR = Portfolio Value × Z-Score × (Annual Volatility / √252) × √Days. Z-Score depends on the confidence level (1.645 for 95%, 2.326 for 99%). The historical method simplifies past data simulation for practical use.

- Higher volatility increases potential loss; adjust based on your risk tolerance.
- Tax implications may affect net losses; consult a financial advisor for personalized advice.
- Compounding frequency is not directly factored here; focus on daily volatility for short-term planning.
