Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled

A statistical measure of the potential loss in value of a portfolio or position over a given time horizon at a given confidence level, stating for example the loss that is not expected to be exceeded on ninety-nine days out of a hundred, computed by historical simulation, parametric or Monte Carlo methods, used by banks, asset managers and regulators for risk management and capital requirements, and criticised for ignoring the size of losses beyond the threshold; value at risk is described here without investment advice.

Why it exists Filled

Let an agent explain value at risk and its definition, calculation methods and limitations, describe its use in regulation and risk management, present criticisms with attribution, and avoid personal investment advice.
