How should a DB plan think about its funded status and its implications?
Funded status (assets − PBO) drives contributions, PBGC fees, P&L, and credit ratings. CIO levers include LDI completion portfolios, glidepath de-risking, and risk-factor budgets.
When should I use a Student-t copula instead of a Gaussian copula?
The Gaussian copula has zero asymptotic tail dependence for any correlation less than one. In plain terms: no matter how correlated two assets appear in normal times...
What are the key design decisions for a target-date fund?
TDF design decisions: asset classes, active vs passive, through vs to retirement, tactical overlay, inflation hedge, fees, benchmark...
How does statistical arbitrage scale pairs trading to hundreds of positions?
Stat arb factor-neutralizes 1000+ stocks, trades residual mean reversion via optimizer. Sharpe 1.5-2.5 but crowded-trade risk is real.
When does GIPS require time-weighted vs money-weighted returns, and how do you calculate each?
GIPS has specific rules about return calculation methods, and the distinction between time-weighted return (TWR) and money-weighted return (MWR, also called internal rate of return or IRR) is a key exam topic.
Can someone walk through surplus optimization for a pension fund step by step?
Surplus optimization applies MVO to surplus returns (assets minus liabilities) rather than asset returns. The key insight is that assets highly correlated with liabilities reduce surplus volatility, making long-duration bonds especially valuable for pension funds even with modest expected returns.
How does a BARRA-style fundamental factor model work?
BARRA-style models use observable firm characteristics as factor exposures and back out factor returns via cross-sectional regression each period.
How do I build a sector-neutral equity strategy?
Sector-neutral matches benchmark sector weights within tight tolerance and generates alpha purely through intra-sector stock selection. Uses optimizer with constraints.
How do banks manage their investment portfolios within ALM?
Bank investment portfolios serve liquidity, interest-rate risk, and yield. HTM/AFS/Trading classification interacts with LCR, capital, and duration management under ALM.
How do property and casualty insurance portfolios differ from life insurance?
P&C insurers invest for short, event-driven liabilities with high liquidity needs. Split portfolio: bond-heavy policyholder book plus risk-on surplus portfolio. Catastrophe stress-testing dominates.
How do copulas model dependence between asset returns beyond linear correlation?
Copulas separate the marginal distribution of each asset from the dependence structure that links them. Sklar's theorem says any joint distribution F(x,y) can be written as C(F_X(x), F_Y(y))...
How do I set up a pairs trading strategy using cointegration?
Test for cointegration via Engle-Granger + ADF. Enter at |z|>2, exit at |z|<0.5, stop at |z|>4. Beta-weight positions and re-estimate quarterly.
How does a Charitable Lead Trust (CLT) work and how is it different from a CRT?
A CLT pays charity first then remainder to family, leveraging low §7520 rates to transfer wealth tax-free when trust returns exceed the assumed rate.
How does Principal Components Analysis build a factor model?
PCA extracts top K principal components as statistical factors, maximizing variance but requiring post-hoc interpretation.
How does a callable swap with early termination feature work?
A callable swap gives one party the right to terminate early. Callable Swap equals Vanilla Swap plus a Swaption owned by the caller...
What is a commodity super-cycle and how should equity investors position for one?
A commodity super-cycle is a 15-25 year period of above-trend prices. Position via diversified miners, royalty companies, and downstream equipment names.
How do desks manage model risk in exotic derivatives?
There's no 'right' model — only models that are fit-for-purpose given their assumptions. Model risk management means acknowledging uncertainty and pricing it in...
How does a life insurance company manage its general account portfolio?
Life insurer general accounts back long-duration liabilities through spread-earning, IG-heavy portfolios with rigorous ALM. Regulatory capital, lapse risk, and spread management dominate decisions.
What are the main types of sovereign wealth funds and their objectives?
SWFs fall into stabilization, savings, pension reserve, reserve investment, and strategic development types. Objectives drive horizon and allocation — from cash-heavy stabilization to 70% equity savings funds.
How is a lifecycle investing glidepath designed?
Glidepaths balance human capital depletion against financial wealth growth, targeting roughly constant total-wealth equity exposure...
