Recognizing that individual risk models can include debatable assumptions about how market data is distributed, the stability of those distributions, the volatility of individual positions and the correlations between the portfolio holdings, it becomes clear that the final risk projections are highly dependent on many assumptions that may, or may not, hold true in the future. Furthermore, additional assumptions about the “correct” period of time to use for a risk analysis or the confidence level selected, further increase the range of projected risk outcomes from even a single risk model.
