Study Notes
Risk Management Cycle
- Risk management is often decentralized within companies, with sub-entities or lines of business having their own risk budgets.
- A risk budget is allocated to each sub-entity, totaling the group's risk budget.
- Local managers control their sub-entity's operations while ensuring their sub-entity's risk doesn't exceed its allocated budget.
- Sub-additivity ensures the group's total risk is less than the sum of individual sub-entity risks.
- This is a method called the allocation of risk budget.
Review of Risk Control
- The risk identification process is reviewed to determine if further risks need consideration.
- Risk assessment procedures and methods are adapted as necessary.
- Risk control adjustments include: limits and thresholds, business models, underwriting and re-insurance policies, and sensitivity scenario characteristics.
- Responsibilities are (re-)defined, along with ongoing monitoring and verification of compliance with the risk strategy.
Mathematics of Risk Management
- Data analytics is a growing field with applications like autonomous driving and fraud detection.
- Data science buzzwords include Machine Learning, Data Mining, Big Data, KDD, and Pattern Recognition.
- Classical Statistical methods are used in quantitative risk management such as simple descriptive statistics, parameter estimation, model fitting, and regression analysis.
Data Analytics - Graphical Tools (QQ Plot)
- A QQ plot compares quantiles of an empirical distribution to a reference distribution.
- It helps evaluate model fitting.
Value of a Fixed-Rate Coupon Bond
- Value depends on the prices of zero-coupon bonds.
- Values are expressed as a formula from present values of coupon payments and face value.
Present Value of a Cashflow Stream
- Values are based on discounted spot rates.
- Values include payments at specific dates in time and expressed as a formula.
Data Analytics - Linear Regression
- Linear regression models functional dependencies between variables, applicable to non-linear relationships with data transformation.
- Multivariate regression extends to multiple variables.
Data Analytics - Time Series
- Time series data analysis considers variables changing over time, such as stock prices, sales data, and virus infections.
- Time series analyze realizations of variables over time.
- Observations of variables across time.
Data Analytics - Financial Time Series
- Log-return on day t is calculated as the difference in stock index value between two trading days in a logarithmic scale.
- Log-returns of various stock indices frequently show volatility changes over time.
- Financial positions are random variables considered with expectations
Risk Measures in Practice
- Risk measures are used for capital buffers against adverse events.
- These measures are useful for risk comparisons and valuation (e.g., risk-adjusted prices).
- They also support corporate management with limit and threshold systems.
Measures of Dispersion vs. Downside Risk Measures
- Measures of dispersion such as standard deviation encompass both positive and negative deviations, whereas downside risk measures focus only on deviations below a certain level.
The Financial Crisis and The Turner Review
- The Turner Review outlined reasons for the 2008 financial crisis.
- It identified increased leverage, changing maturity transformation and misplaced trust in sophisticated mathematical models as important contributors.
- While complex mathematical models were used, they did not adequately capture the real-world risks.
