- Scenarios can be driven by events or problems that may arise from a company's portfolio of business lines and risks. Event-driven scenarios are based on plausible events and how they might affect a firm. Portfolio-driven scenarios are driven by the vulnerabilities of the portfolio held by a firm.istorical scenarios are easier to design, but hypothetical scenarios are more flexible. Stochastic scenarios are based on simulations -- typically between 1,000 and a million -- and are driven by adjustments to the parameters and input variables, based on their historical distributions and co-variances.
