Information ratio maximization combines information coefficient, breadth, and transfer coefficient via the Fundamental Law of Active Management, solved via quadratic programming.
Is there a case for allocating to international small-cap equities?
International small-cap offers lower correlation to US equities (~0.68), historically higher returns, and exposure to domestic economic drivers. Typical allocation is 5–15% of the international equity sleeve.
Why do investors exhibit home-country bias and how do I quantify it?
Home-country bias is measured as the overweight vs global market cap share. Drivers include familiarity, FX aversion, liability matching, and behavioral factors. Typical bias far exceeds rationally justifiable levels.

How do I identify a rising star credit before the upgrade?
Rising stars are HY issuers on track to be upgraded to investment grade. Spotting them early captures spread tightening of 100-300 bp.
How does best-subsets regression work and when is it feasible?
Best-subsets regression evaluates every possible combination of predictors and picks the best one by a chosen criterion. It's exhaustive rather than greedy.
What is stepwise regression and why has it fallen out of favor?
Stepwise regression iteratively adds or removes predictors based on p-values. It was standard practice for decades but modern statisticians identify serious problems.
Which financial ratios matter most in corporate credit analysis?
Credit ratios fall into three families: leverage (Debt/EBITDA <3x IG), coverage (EBITDA/Interest >3x IG), and cash flow (FFO/Debt >20% IG). Compare against peer median and 3-5 year trend. For Meridian Outdoor: 4.2x leverage + 15% FFO/Debt = BB consistent...
How does a calendar spread profit from time decay?
A calendar spread profits from differential time decay — the short near-term option decays faster than the long longer-dated option at the same strike.
Calendar rebalancing vs. percent-range rebalancing — pros, cons, and when to use each?
Calendar rebalancing trades on a fixed schedule (simple but inflexible), while percent-range rebalancing uses corridors around target weights (responsive but requires monitoring). Corridor width depends on transaction costs, volatility, correlation, and risk tolerance.
How does a butterfly spread work and when is it the right trade?
A butterfly spread profits maximally when the underlying pins at the middle strike, offering high reward-to-risk on a narrow price target.
When can financial liabilities be measured at amortized cost versus fair value?
IFRS 9 defaults liabilities to amortized cost using effective interest method. FVTPL applies for trading liabilities, inseparable embedded derivatives, or elected FVO. Modifications trigger 10% cash flow test.
What is Operational Due Diligence in PE fund selection?

What is blue ocean strategy and how do I value a company pursuing it?
Blue ocean strategy creates uncontested market space via the four actions: eliminate, reduce, raise, create. Valuation challenges include no comparable multiples, long education ramps, and uncertain TAM...
What are dynamic capabilities and how do they differ from static resources?
Dynamic capabilities extend RBV by emphasizing the ability to sense opportunities, seize them by mobilizing capital, and transform by reconfiguring assets. Measured by R&D intensity, pivot speed, and retraining depth...
What is CDS basis and how do positive vs negative basis trades work?
CDS-bond basis is the difference between CDS spread and cash bond Z-spread. In theory it should be zero; in practice deviations create arbitrage opportunities...
What is longevity insurance (deferred income annuity) and when is it optimal?
A deferred income annuity (DIA), often called longevity insurance, is purchased at one age with payments beginning at a later age.
Is factor timing a viable strategy?
Factor timing varies exposures to style factors based on predictive signals. Evidence is mixed — valuation spreads predict value factor returns, but most timing signals fail out-of-sample...
How is key rate PV01 computed and what does it tell me that duration doesn't?
KR01 measures dollar change for a 1bp shift at one key rate, holding others constant. Reveals curve-shape exposures that single-number duration hides.
How does importance sampling reduce variance in Monte Carlo?
Importance sampling replaces the original density with a proposal, then weights samples by p/q. Choose the proposal to put probability mass where the integrand matters most...
