Introduction

• Financial Risk management helps organizations
  identify, manage and adopt strategies to mitigate
  risks. Generally for the students in finance
  studying risk management, it is essential to
  learn how to evaluate risk management models.
• A risk management model evaluates the existing
  and anticipated risks that directly impacts the
  financial health of a company and helps in
  adopting strategies to minimize these risks. This
  presentation will act as a guide to learn the
  five important metrics involved in the evaluation
  of risk management models, supported by few
  examples for better understanding.

Steps Involved in Evaluating Risk Management
Models
4

• Evaluating risk management models involves
  several key steps
• Define Objectives Identify what the risk
  management model is supposed to deliver. for
  instance, reducing on potential losses or
  maximizing on risk adjusted returns.
• Select Appropriate Metrics Select the right
  metric leads depending on the objective and the
  type of risks, such as VaR, CVaR, stress testing,
  backtesting and RAROC.
• Data Collection and Preparation Collect
  accurate, valid and comprehensive data which is
  consistent with existing and potential market
  conditions.
• Model Calibration and Testing Do the model
  calibration by utilizing historical data and
  backtesting to make sure the model performs as
  per the expectation in different situations.
• Continuous Monitoring and Updating The model
  should be reviewed and updated on the regular
  basis in light of changes in the market
  conditions, regulations and the organizations
  risk tolerance level.

5 Key Metrics for Evaluating Risk Management
Models

1. Value at Risk (VaR)

• Value at Risk or VaR is a well-known metrics used
  in risk management. It seeks to determine the
  highest possible loss that an investment
  portfolio could reach within a specific period of
  time in given confidence level. For example, if a
  portfolio has a daily VaR of 1 million at a 95
  confidence level, it means there is a 95
  probability that the portfolio will not lose more
  than 1 million in a day.
• Case Study JPMorgan Chase's Use of VaR
• VaR has been integrated into the JPMorgan Chases
  daily risk management model. The Chief Investment
  Office of the JPMorgan failed to properly assess
  the risk during the 2008 financial crisis, which
  resulted into heavy loss. Such example proves
  that, in addition to calculating the VaR, it is
  crucial to take the drawbacks of this method into
  account. For instance it supposes that market
  conditions remain normal and does not take into
  consider extreme events.

2. Conditional Value at Risk (CVaR)

• Conditional Value at Risk (CVaR), also known as
  Expected Shortfall, takes the concept of VaR a
  step further by attempting to look at the
  distribution of loss beyond VaRs limits. It
  gives a average of the worst-case losses giving a
  better risk assessment.
• Example Application in Portfolio Management
• Let us consider a hedge fund managing a portfolio
  with high exposure to volatile assets. Thus,
  using CVaR, the fund managers can assess the
  average losses in the worst-case conditions,
  thus, draw up an optimal strategy in the context
  of possible economic crises.

3. Stress Testing and Scenario Analysis

• Stress Testing analyze the performance of a risk
  management model in adverse market conditions. On
  the other hand, Scenario Analysis analyses the
  Models reaction in certain hypothetical
  circumstances. Such metrics make it possible to
  detect the vulnerabilities in risk management
  strategies.
• Illustration 2008 Financial Crisis
• In 2008 many financial institutions were caught
  out because of poor stress testing. The crisis
  showed we need stress tests that include severe
  economic downturns, like a sudden housing price
  collapse or a market meltdown.

4. Backtesting

• Backtesting is testing a risk model against
  historical data to see how well it predicts the
  actual outcome. It validates the model by
  comparing what it said would happen to what
  actually happened.
• Case Study Hedge Fund Backtesting
• A hedge fund backtests its risk model against the
  dot-com bubble data. If it gets the losses right,
  then its good for similar future conditions.

5. Risk-Adjusted Return on Capital (RAROC)

• Risk Adjusted Return on Capital or RAROC is a
  tool to evaluate the return on investment
  considering the risk. It is most useful when you
  want to compare the profit of investment or
  business segments controlling for the amount of
  risk.
• Example Bank Loan Portfolios
• RAROC helps banks to evaluate the performance of
  its loan portfolio against the risk exposure. A
  high RAROC means the bank is getting good returns
  for the risk taken hence can be used in decision
  making on loans to issue and manage the portfolio.

Challenges Faced by Students in Evaluating Risk
Management Models
12

• Students often face several challenges when
  evaluating risk management models
• Understanding Complex Mathematical Concepts Most
  of the risk measures require the use of complex
  and advanced mathematical computations and
  becomes challenging if a student is not very good
  in statistics and finance.
• Data Availability and Quality Another challenge
  is accurate data for testing and calibrating the
  models may be difficult to obtain, especially for
  students having no industry affiliation.
• Keeping Up with Evolving Models Modern Risk
  management models are constantly evolving and
  getting updated with new methodologies and
  multi-dimensional data. Staying updated with the
  recent trends can be challenging.

Potential Exam Questions and How We Answer Them
16

• "Explain the difference between VaR and CVaR and
  discuss their uses in risk management."
• Answer VaR estimates the highest possible loss
  for a given time span and confidence level, CVaR
  considers the average of losses beyond the VaR
  level, making it a more reliable risk management
  tool. VaR is very helpful to measure the possible
  loss in normal circumstances while CVaR is very
  helpful in the extreme circumstances.
• "How would you conduct a stress test for a bank's
  loan portfolio?"
• Answer Running a stress test involves creating
  extreme but plausible economic scenarios, such as
  a sharp drop in real estate prices or a sudden
  increase in interest rates. The performance of
  the banks loan portfolio under these conditions
  is then analyzed, possible weaknesses are
  determined and further risk management strategies
  are implemented.

• Textbooks
• "Risk Management and Financial Institutions" by
  John Hull
• "The Essentials of Risk Management" by Michel
  Crouhy, Dan Galai, and Robert Mark
• "Value at Risk The New Benchmark for Managing
  Financial Risk" by Philippe Jorion An excellent
  resource for understanding the theory and
