Monte Carlo simulation and other open-form techniques will become the basis for measuring risk in large portfolios. In the past, the goal was to obtain closed-form solutions, equations that pre-ordained the answer once the variables were filled in. Open-form techniques, which have only become feasible with the advent of computers, do not produce a single predetermined result.
