What is the Jarque-Bera test and how do you use it to check if financial returns are normal?
The Jarque-Bera (JB) test is a joint test of whether a sample's skewness and excess kurtosis are consistent with a normal distribution. It is one of the most commonly referenced normality tests in FRM.
How do banks aggregate risk across trading desks, and what are the challenges with recognizing diversification benefits?
Banks aggregate desk-level VaR using correlation matrices, benefiting from diversification. However, correlations spike during crises, and regulators impose floors on aggregation benefits. The Basel FRTB framework uses ES with prescribed correlation parameters.
How is economic capital for credit risk calculated, and how does it differ from regulatory capital?
Economic capital covers unexpected credit losses at a chosen confidence level. It equals the loss quantile minus expected loss, reflecting the capital buffer needed beyond provisions to absorb tail risk events.
How does excess kurtosis (fat tails) affect VaR calculations, and what can you do about it?
Fat tails mean extreme returns occur far more often than Normal predicts, causing standard VaR to underestimate risk by 3-700x depending on the event severity. Fixes include Cornish-Fisher expansion, Student-t distributions, and Extreme Value Theory.
How do principal-protected notes work, and what are the hidden risks most investors miss?
Principal-protected notes (PPNs) are structured products that promise return of principal at maturity while offering upside participation. They combine a zero-coupon bond with a call option, but carry hidden risks including issuer credit risk and opportunity cost.
How does reverse stress testing work in practice and what makes it different from regular stress tests?
Reverse stress testing inverts the traditional approach: instead of asking how bad losses could get, it asks what would have to happen for the firm to fail. This methodology is uniquely powerful for uncovering hidden vulnerabilities.
What is the Fundamental Review of the Trading Book (FRTB), and how does it change market risk capital?
The Fundamental Review of the Trading Book (FRTB) is a major overhaul of market risk capital requirements. Key changes include replacing VaR with Expected Shortfall, introducing the sensitivities-based standardized approach (delta, vega, curvature), requiring desk-level model approval, and capitalizing non-modellable risk factors.
How does scenario-based capital assessment work under AMA?
Under the Advanced Measurement Approach (AMA), scenario analysis outputs directly inform the operational VaR at 99.9% confidence over a one-year horizon...
How does a pension glide path work mechanically?
A glide path uses funded-ratio triggers to shift allocation from return-seeking to liability-hedging as surplus grows.
What is the maturity adjustment in the IRB formula and why does longer maturity need more capital?
MA = (1 + (M-2.5)·b(PD)) / (1 - 1.5·b(PD)), where b(PD) = [0.11852 - 0.05478·ln(PD)]². 5Y loan gets 51.8% more capital than 2.5Y baseline. Captures migration risk...
What are the steps in the risk management process cycle, and how do they connect?
The risk management process is a continuous five-stage cycle: identification, assessment and measurement, mitigation and control, monitoring and reporting, and governance review. Each stage feeds into the next, with a critical feedback loop from governance back to identification that keeps the framework current.
What are the main types of exotic options, and how do they differ from vanilla options in risk characteristics?
Exotic options include barrier options (activated or deactivated at trigger prices), Asian options (payoff based on average price), and lookback options (payoff based on the extreme price observed). Each has different premium levels, path dependencies, and hedging complexities compared to vanilla options.
How do you invest in commodities and what is roll yield? I keep seeing terms like contango and backwardation.
Commodity futures returns consist of spot return, roll yield, and collateral yield. Contango (futures above spot) creates negative roll yield, while backwardation (futures below spot) creates positive roll yield that enhances returns.
What are the '4 Vs' of big data and what challenges do they create for investment analysis?
The 4 Vs of big data — volume, velocity, variety, and veracity — describe both the characteristics and challenges of working with alternative data in investment analysis. Each V creates specific processing, integration, and reliability problems.
Why do companies choose share repurchases over dividends, and what signal does each send?
Share repurchases and dividends both return cash to shareholders, but buybacks offer greater tax efficiency, flexibility, and a stronger undervaluation signal. However, they can also be used to manipulate EPS and may not always create value.
What are the main types of exotic options and when would you use each one?
Exotic options modify one or more features of standard options to address specific hedging or speculative needs. The main types include barrier options, Asian options, lookback options, and digital options, each solving different practical problems.
How do you account for subsidiaries in hyperinflationary economies?
Hyperinflation occurs when cumulative three-year inflation approaches 100%. Under IFRS, subsidiaries in hyperinflationary economies first restate their statements for inflation (IAS 29), then translate at the current rate. Under US GAAP, the temporal method is used directly.
How should I analyze a balance sheet for current vs non-current classifications and off-balance-sheet items?
Balance sheet analysis requires understanding current vs non-current classification (based on the one-year or operating cycle rule) and identifying off-balance-sheet items like operating leases, SPEs, contingent liabilities, and purchase commitments.
What are the unique risks and opportunities in emerging market debt?
Emerging market debt offers higher yields but carries unique risks including sovereign default, currency depreciation, political instability, liquidity constraints, and contagion. Portfolio managers must choose between hard and local currency exposure based on risk budget and return objectives.
What are the key differences in pension expense reporting between IFRS and US GAAP?
The key differences lie in how each framework handles the return on plan assets and actuarial gains/losses. IFRS uses a single net interest rate, while US GAAP separates interest cost and expected return. Actuarial items never recycle from OCI under IFRS but are amortized via the corridor approach under US GAAP.
