What qualifies as a Level 1 input under the fair value hierarchy?
Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities. Three conditions must all hold: active market, identical instrument, and entity access at measurement date.
How does one-class SVM work for outlier detection?
One-class SVM learns a boundary around normal data in kernel space, labeling points outside as outliers; best for moderate-size datasets with compact normal regions.
What are the core drivers of shareholder value I should track?
Rappaport's classic framework narrows shareholder value drivers to seven. In practice, four dominate 80% of value creation.
What is a non-deliverable forward (NDF) and why is it used for emerging market currencies?
An NDF is a cash-settled FX forward in which no physical exchange of the underlying currency occurs. It exists precisely because some emerging market currencies have capital controls.
What's the intuition behind covered interest rate parity and when does it break down?
Covered interest rate parity (CIP) says that a fully-hedged foreign investment must earn the same return as a domestic deposit.
How do I derive implied ERP directly from market prices?
Implied ERP: solve DCF of aggregate equity cash flows for the ke that matches current index. For S&P at 5,840 with 5-year growth 6% fading to 4.25%: ke ≈ 8.8%, ERP ≈ 4.55%. Sensitive to growth assumptions...
How do I identify the principal market for fair value measurement?
Principal market is the market with greatest volume and activity that the entity can access. If not identifiable, use the most advantageous market. Transaction costs inform selection but are excluded from fair value.
What is the J-curve in private equity and why does it happen?
The J-curve reflects early fee drag and slow deployment before exits and markups drive late-life returns.
How do I distinguish a joint venture from a joint operation under IFRS 11?
IFRS 11 classifies joint arrangements by rights and obligations, not legal form. A joint venture gives rights to net assets, while a joint operation gives direct rights to assets and obligations for liabilities...
Why do the first three PCA components of yield curves represent level, slope, and curvature?
PCA of yield changes consistently produces three dominant components with recognizable level, slope, and curvature shapes. The first factor explains 70-80% of variance...
Why do callable bonds and mortgage-backed securities exhibit negative convexity?
Callable bonds and MBS exhibit negative convexity because issuer or homeowner refinancing caps the upside while the downside remains fully open.
How does Bayesian estimation differ from frequentist?
Frequentist: parameters are fixed unknowns; data is random. Bayesian: parameters are random variables with probability distributions; data updates beliefs...
How do I interpret a deteriorating Days Inventory trend across sectors?
Industry-specific benchmarks matter: food 25-50 days, tools 80-120, apparel 95-150. Verdant's food inventory buildup signals spoilage risk; SilverLink's 53% DSI surge predicts 30-50% markdowns; Ironclad requires deeper demand analysis.
When does a contract have a significant financing component, and how does it affect revenue?
If payment timing provides significant financing benefit, adjust transaction price to cash selling price and recognize the difference as interest income or expense. Practical expedient for periods under one year.
Right-to-access vs right-to-use IP licenses — how do they differ for revenue timing?
Right-to-use licenses recognize revenue at a point in time (static IP). Right-to-access licenses recognize over time because the licensor undertakes activities significantly affecting the IP.
What is walk-forward testing and when should I use it?
Walk-forward re-estimates on rolling windows, producing concatenated OOS returns. Caldera Capital's sector rotation: OOS Sharpe 0.8 vs IS 1.4, realistic decay.
How do I normalize asset turnover for cyclical businesses, and why does it matter for DuPont?
Cyclical asset turnover swings with demand while assets stay fixed — normalize to mid-cycle using multi-year averages or peak-capacity adjustments.
How does farmland investing generate returns and what drives performance?
Farmland returns come from cash income from renting land or selling crops, and capital appreciation driven by land-value growth over time.
How is cost curve analysis used for commodity equities?
Cost curves show industry production sorted by cost. Marginal producer sets price; Q1 producers earn durable margins through cycles.
How does DCC-GARCH model time-varying correlation between assets?
Engle's Dynamic Conditional Correlation (DCC) GARCH decomposes the multivariate volatility problem in two stages. First, you fit a univariate GARCH to each series...
