This document discusses Value at Risk (VaR) and related concepts over multiple learning outcomes (LOs). It introduces VaR and explains why it was widely adopted as a risk measure. It also defines how to calculate VaR for single and multiple assets, and how to convert between time periods. The document discusses assumptions of VaR calculations and reasons for using continuously compounded returns. It also addresses factors that affect portfolio risk and how to calculate VaR for linear and non-linear derivatives. Finally, it introduces cash flow at risk (CFaR) and how VaR and CFaR can be used to evaluate projects and allocate risk.
