# Market Risk Measurement and Management

## Reading 6 (Correlation basics...) LO 6.d - Risk Management (Schweser Book 1, Page no 73)

Standard deviation of the portfolio = (Bh X C X By)

Above formula is given in the reference topic, however inputs are the same as a normal calculation for standard deviation using weights.

I am not able understand, how to identify which formula to use - I mean in exam, when we see inputs for standard deviation calculation, we will tend to use the formula with weights.

Any solution/thoughts?

## Delta Hedging a short call with a long stock

I’m having trouble understanding the following statement

“If the delta of a call option is 0.4, then in order to hedge the sold call option, the option seller needs to purchase 0.4 stocks for every option sold”

I understand the math behind delta. What I don’t understand is, why does someone hedge a sold call? (While the call itself is a hedge)

Is it to be able to close the short call position and exit their obligation in the event that the spot price of the underlying far exceeds the strike price?

## what rate of return to use in Monte Carlo Sim

Hi All, I have been reading for days trying to get to the bottom of this question, however I don’t have a solid enough math background to reach the answer. I want to simulate the performance of an asset and I am assuming it is normally distributed and it will behave in a similar manner in the future.

1-) Take the daily changes in an assets price

2-) Apply natural log on those price (LN)

3-) Calculate the Average and Sd of (2)

4) Multiple the average by 250 to arrive at the annual expected return and Sd by Sqrt(250) to arrive at annual volatility

## Joint Probability With Hazard Rate

Hello, I found out two different methods to calculate the probability: Here you are the question and answer:

Question 1:

## Lognormal Var Formula Question

Hello, I’m confused about a very easy question, how to calculate the lognormal Var. Here you are the question and answer:

## 10 year bond equivalent notional

how is this calculated?

## Question about the 2009 practice exam 2, question 1.

The answer is B. However, I don’t think this is the right answer. My calculation is as follows:

Assuming we should buy x contracts,

300100000*1.1/(300100000+x*250*1457)+x*250*1457/(300100000+x*250*1457)=0.75.

That is, x=-1153.

It will be grateful if anyone could point out my mistake in calculation.

## Wiley: FRM Exam Review - Study Guide part II - errata or am I wrong?

Hi,

I’m studying with the new material from Wiley, but I’ve found some (I think) inconsistencies:

A) volume 1 page 59: the formula at the center of the page should be 1000/(1+0.065/2)=968.52 and not 1000(1+0.065/2)…
