Forward Risk

If you need to estimate how much you could lose on a portfolio, this handles the standard risk toolkit: parametric VaR using variance-covariance, Monte Carlo simulation for non-normal distributions, Expected Shortfall for tail risk beyond VaR, and component/marginal VaR to see which positions contribute most to total risk. It also covers stress testing and scenario analysis with historical or hypothetical shocks. The formulas are straightforward and it walks through converting daily to multi-day horizons, decomposing risk into systematic factors versus idiosyncratic noise, and the difference between coherent measures like CVaR and plain VaR. Useful for regulatory capital calculations or just understanding your downside before things get ugly.
