— Use a factor model to generate a forward-looking portfolio value distribution, which relates each asset class to the same core set of factors using asset-class-specific conditional valuation functions
— Measure risk of the portfolio in terms of simulated volatility and probability of large drawdowns in portfolio value
— Estimate the contribution of each individual exposure/position/sub-portfolio to portfolio volatility and expected shortfall (average loss in down-states of portfolio value)
— Compare risk measures to expected return measures (i.e., risk premia) — Estimate the portfolio's fragility
