3.The Market Line (ML) and CAPM Small recap Capital Market Line (CML) obtained by combining the market portfolio and the riskless assetPart 1. Portfolio Performance Measurement • CML specifies the expected return for a given level of risk • All possible combined portfolios lie on the CML, and all are Mean-Variance efficient portfolios • Here we have a clear relation between the risk of my portfolio and the riskLecture 6 of the market. This is reflected by beta Cov( Ri , RM ) It measures how much an asset’s return bi is driven by the market return 2M
3.The Market Line (ML) and CAPM Small recap Capital Market Line (CML)Part 1. Portfolio Performance Measurement If the stock has a high positive β: • It will have large price swings driven by the market • It will increase the risk of the investor’s portfolio(in fact, will make the entire market more risky …) • The investor will demand a high Er in compensation. If the stock has a negative β : • It moves “against” the market. • It will decrease the risk of the market portfolio • The investor will accept a lower Er Then the SML depicts the relation between β and the Expected Return (Er)Lecture 6 For the risk-free security, b = 0 For the market itself, b=1.

4.Treynor Ratio The Treynor measure calculates the risk premium per unit of risk (bi)Part 1. Portfolio Performance Measurement [ E ( RP ) RF ] TR b ( RP ) Beta measures the investment volatility relative to the market volatility (systematic risk) The Treynor Ratio is negative if • RF > E[RP] AND β > 0 . Manager has performed badly: failing to get performance better than the risk free rate AND manager made a not good election of portfolio • RF < E[RP] AND β > 0 Manger has performed well, managing to reduce risk but getting aLecture 6 return better than the risk free rate Higher Ti generally indicates better performance
4.Treynor Ratio ADVANTAGE: It indicates the volatility a ASSET brings to an entire portfolio. The Treynor Ratio should be used only as a ranking mechanism forPart 1. Portfolio Performance Measurement investments within the same sector. . When presented with investments that have the same return, investments with higher Treynor Ratios are less risky and better managed Cov( Ri , RM ) bi 2MLecture 6
5. Sharpe Ratio Describes how much excess return you are receiving for the extra volatility that you endure for holding a riskier asset.Part 1. Portfolio Performance Measurement [ E ( RP ) RF ] SR ( RP ) The Sharpe measure is exactly the same as the Treynor measure, except that the risk measure is the standard deviation: • Tells us whether a portfolios returns are due to smart investment decisions or a result of excess risk. • The greater a portfolios Sharpe ratio, the better its risk-adjusted performance has been. • A negative Sharpe ratio indicates that a risk-less asset would performLecture 6 better than the security being analysed.

6. Sortino Ratio The Sortino ratio generalizes (focus on the downside) from the Sharpe by using:Part 1. Portfolio Performance Measurement • In the numerator, instead of excess return (above riskfree), Sortino uses excess above hurdle (MAR, minimum acceptable return) • In the denominator, instead of volatility (annualized standard deviation), Sortino uses downside deviation. [ E ( RP ) MAR] SR L ( RP ) • Appears to resolve several of the issues inherent in the Sharpe ratio: • It incorporates a relevant return target, in both the numerator and the denominator; • It quantifies downside volatility without penalizing upside volatility; and because of its focus on downside risk, • It is more applicable to distributions that are negatively skewed thanLecture 6 measures based on standard deviation.

9. Modigliani´s Risk Adjustment Performance • Also known as M2 • Closely related to the Sharpe RatioPart 1. Portfolio Performance Measurement • Focuses on total volatility as a measure of risk, but its risk adjusted measure of performance has the interpretation of a differential return relative to the benchmark index • The idea is to lever or de-lever a portfolio (i.e., shift it up or down the capital market line) so that its standard deviation is identical to that of the market portfolio. • The formula for M2 is: M 2 M R i R f R f i Lecture 6 • The M2 of a portfolio is the return that this adjusted portfolio earned. This return can then be compared directly to the market return for the period.

1. Introduction Definition The potential for loss due to failure of a borrower to meet its contractual obligation to repay a debt in accordance with the agreed terms • Its effect is measured by the cost of replacing cash flows if the other party defaults • Commonly also referred to as default risk • Credit events includePart 3. Credit Risk Management • bankruptcy, • failure to pay, • loan restructuring • loan moratorium • Example: A homeowner stops making mortgage payments Market Risk Credit Risk Potential loss due to the non Potential loss due to changes in performance of a financialLecture 6 market prices or values contract, or financial aspects of non performance in any contract

It has associated the Probability of Default (PD) defined as the likelihood that the borrower will fail to make full and timely repayment of its financial obligations Exposure At Default (EAD)Part 3. Credit Risk Management The expected value of the loan at the time of default Loss Given Default (LGD) The amount of the loss if there is a default, expressed as a percentage of the EAD Recovery Rate (RR) The proportion of the EAD the bank recoversLecture 6
3. Settlement risk In initial consideration Settlement risk: The risk that one party will fail to deliver the terms of a contract with another party at the time of settlement Foreign exchange (FX) settlement risk is the risk of loss when a bank in a foreign exchange transaction pays the currency it sold but does not receive the currency it bought.Part 3. Credit Risk Management Settlement Risk management: • Real time systems • Bilateral netting agreements (two institutions) • Multilateral netting agreements (two industries) CLS Bank. In foreign exchange and operates the largest multicurrency cash settlement system. It is owned by the worlds leading financial institutionsLecture 6
4. Credit losses (overview) Set up: The credit losses are defined by CL i 1 bi * CEi * (1 f i ) N Where • Random Variable bi is a bernoulli trial that takes values of 1 (Def) or 0 (non Def) • CEi is the Credit Exposure at time of default • fi is the recovery rate (What means 1-fi )Part 3.
