Risk Management Flashcards
26.a: Discuss features of the risk management process, risk governance,
risk reduction, and an enterprise risk management system.
**The risk management process requires: **
1. Top level management of the organization setting policies and procedures for
managing risk.
2. Defining risk tolerance to various risks in terms of what the organization is willing
and able to bear. For some risks tolerance will be high, for others it will be low.
3. Identifying risks faced by the organization. Those risks can be grouped as financial
and non-financial risks. This will require building and maintaining investment
databases for both types of risk.
4. Measuring the current levels of risk.
5. Adjusting the levels of risk-upward where the firm has an advantage and seeks
to generate return to exploit an advantage, downward in other cases. As part of
adjusting risk levels the firm must:
Risk governance -overall process of developing and putting a risk management system into use.
LOS 26.b: Evaluate strengths and weaknesses of a company’s risk management
process.
LOS 26.c: Describe steps in an effective enterprise risk management system.
A
Identify each risk factor to which the company has exposure.
Quantify the factor in measurable terms.
Include each risk in a single aggregate measure of firm-wide risk. VAR will be the
most commonly used tool.
Identify how each risk contributes to the overall risk of the firm. This is an
advantage of VAR.
Systematically report the risks and support an allocation of capital and risk to the
various business units of the firm.
Monitor compliance with the allocated limits of capital and risk.
26.d: Evaluate a company’s or a portfolio’s exposures to financial and
nonfinancial risk factors.
Market risk - interest rates, exchange rates, equity prices,
commodity prices,
Credit risk - the risk of loss caused by a counterparty’s or debtor’s failure to make a promised payment.
Liquidity risk is inability to take or liquidate a position quickly at a fair price.
Operational or operations risk is a loss due to failure of the company’s systems and procedures or from external events outside the company’s control.
Settlement risk - One party could be making a payment while the other side of the exchange could be in the process of defaulting and fail to deliver on the transaction. ( Herstatt risk)
Model risk/ Sovereign risk / regulatory risk / tax accounting and legal / contract risk
Performance netting risk / Settlement netting risk
26.e: Calculate and interpret value at risk (VAR) and explain its role in
measuring overall and individual position market risk.
The percentage selected will affect the VAR. A 1 % VAR would be expected to show
greater risk than a 5% VAR.
( refer orignal cfa materia)
26.D Compare the analytical (variance-covariance), historical, and
Monte Carlo methods for estimating VAR and discuss the advantages and
disadvantages of each
5% VAR is 1.65 standard deviations below the mean.
• 1 % VAR is 2.33 standard deviations below the mean.
Disadvantages of -
Many assets exhibit leptokurtosis (fat tails). When a distribution has “fat tails,” VAR
will tend to underestimate the loss and its associated probability as extreme returns occur more frequently than assumed by the normal distribution.
The difficulty of estimating standard deviation in very large portfolios.
26.g: Discuss advantages and limitations of VAR and its extensions,
including cash flow at risk, earnings at risk, and tail value at risk.
Incremental VAR (IVAR) is the effect of an individual item on the overall risk of the portfolio. IVAR is calculated by measuring the difference between the portfolio VAR before and after an additional asset, asset class, or other aspect of the portfolio is changed
Cash flow at risk (CFAR) ——–
26.h: Compare alternative types of stress testing and discuss advantages
and disadvantages of each.
Scenario analysis is used to measure the effect on the portfolio of simultaneous movements in one or several factors.
Other forms of scenario analysis include actual extreme events and hypothetical events,
which are quite similar.
Stress testing is just an extreme scenario.
Factor push analysis is a simple stress test where the analyst pushes factors to the
most disadvantageous combination of possible circumstances and measures the
resulting impact on the portfolio.
Maximum loss optimization uses more sophisticated mathematical and computer
modeling to find this worst combination of factors.
Worst-case scenario is the worst case the analyst thinks is likely to occur.
LOS 26.i: Evaluate the credit risk of an investment position, including forward
contract, swap, and option positions.
Current credit risk (also called jumpto-default risk) is the amount of a payment currently due. Because payments are only due on specific dates, current credit risk is zero on all other dates.
Potential credit risk is associated with payments due in the future and exists even if there is no current credit risk. It will change over time.
cross-default-provisions
interest rate and equity swaps - credit risk is hgiher in the middle of the life cycle - for currency swap it is at the end of the life
LOS 26.j: Demonstrate the use of risk budgeting, position limits, and other
methods for managing market risk.
Risk budgeting which risks are acceptable and how total enterprise risk is allocated across business units or portfolio managers.
LOS 26.k: Demonstrate the use of exposure limits, marking to market,
collateral, netting arrangements, credit standards, and credit derivatives to
manage credit risk.
Limiting exposure - limiting the amount of loans to any individual debtor or the amount of derivative transactions with any individual counterparty.
Marking to market-. The party whose value is negative pays this amount to the other party, and the contract is repriced.
Payment netting , close out netting
Transferring Credit Risk with Credit Derivatives -
credit default swap, the protection buyer pays the protection seller in return for the right to receive a payment from the seller in the event of a specified credit event.
In a total return swap, the protection buyer pays the total return on a reference obligation (or basket of reference obligations) in return for floating-rate payments. If the reference obligation has a credit event, the total return on the reference obligation should fall; the total return should also fall in the event of an increase in interest rates, so the protection seller (total return receiver) in this contract is actually exposed to both credit risk and interest rate risk.
A credit spread option is an option on the yield spread of a reference obligation and over a referenced benchmark
a credit spread forward is a forward contract on a yield spread.
26.l: Discuss the Sharpe ratio, risk-adjusted return on capital, return
over maximum drawdown, and the Sortino ratio as measures of risk-adjusted
performance.
The Sharpe ratio measures excess return (over the risk-free rate) per unit of risk,
measured as standard deviation.
it can’t be used for non- linear returns
Risk-adjusted return on invested capital (RAROC). RAROC is the ratio of the
portfolio’s expected return to some measure of risk, such as VAR . Management can then compare the manager’s RAROC to his historical or expected RAROC or to a benchmark RAROC.
Return over maximum drawdown (RoMAD). RoMAD is the annual return divided by
the fund or portfolio’s largest percentage drawdown.
The Sortino ratio is the ratio of excess return to risk. Excess return for the Sortino
ratio (the numerator) is calculated as the portfolio return less the minimum acceptable portfolio return (MAR).
Sortino ratio = (Mean portfolio return – MAR)/Downside deviation
26.m: Demonstrate the use of VAR and stress testing in setting capital
requirements.
Nominal, notional, or monetary position limits.
Max loss limits.
Internal and regulatory capital requirements.
Behavioral conflicts.
Cons:
VAR is only as good as the assumptions used in its calculation, and it does not
consider all worst-case scenarios.
VAR may not be well understood by the business units.
Diversification issues can be counterintuitive. It may be appropriate to allocate
capital to a very low return unit if the diversification benefit is large enough to allow
an increase in allocation to a higher risk and return unit.
Stress testing is the natural complement to VAR as it can consider more extreme outlier
events that may not be reflected in the VAR calculation.
27 A. demonstrate the use of equity futures contracts to achieve a target beta for a
stock portfolio and calculate and interpret the number of futures contracts
required;
((Bt-Bp)/Bf)*(Vp/Pf*Multiplier)
Bt = Desired portfolia beta
Bp =Portfolia beta
27 B construct a synthetic stock index fund using cash and stock index futures
(equitizing cash);
c explain the use of stock index futures to convert a long stock position into synthetic
cash;
