**CFA Practice Question**

A portfolio manager is reviewing a research report generated from running the Monte Carlo simulation model for 4 pass-through securities. There is an obvious error about the data of one security. Which one is it?

A. A or B

B. C

C. D

**Explanation:**Higher interest rate volatility implies lower prices of these pass-through securities. For security C, the price is 95 when the volatility is 10%, and its price should be less than 95 when the volatility is 12%. However, it's estimated to be higher (97).

Given these are results from a Monte-Carlo analysis, this would call into question ALL of the securities' results. Since Monte Carlo analyses will (probabilistically) even produce extreme results, the table above can easily be produced by a Monte Carlo run with too few scenarios. |

Mathematically the price ranges given should increase with interest rate volatility. This is not true for the 15% group. |
