How do I do factor-based performance attribution?
Decompose excess return into β_k × factor_return_k contributions plus residual alpha from stock selection.
How do I account for jointly controlled assets such as shared pipelines?
Jointly controlled assets are a subset of joint operations. Each party recognizes its share of the asset by its nature, its own liabilities, jointly incurred liabilities, output income, and shared expenses...
What is a jointly controlled operation and how is it accounted for?
A jointly controlled operation means parties share control without forming a separate entity. Each party uses its own assets, incurs its own expenses, and recognizes its share of output revenue...
What are the main applications of PCA in finance?
PCA transforms correlated variables into uncorrelated components ordered by variance. In finance, applications include yield curve analysis, factor models, stress testing...
How do I identify a genuine mega-trend rather than a fad?
The 5D filter tests mega-trends on demographics, inelasticity, disruption depth, dollar scale, and duration. Passing 4 of 5 distinguishes mega-trends from fads.
What is GMM and why is it so common in asset pricing?
GMM estimates parameters by making a set of moment conditions hold on average. Moment conditions are functions with theoretical expectation zero under the true theta...
How do I evaluate the adequacy of inventory obsolescence reserves?
Compare reserve-to-gross-inventory ratio vs peers, examine roll-forward (additions vs actual write-offs), and analyze aging. Apex's 12.4% vs peer 8.7% suggests $12.4M potential cushion if product mix doesn't justify excess.
How do loyalty points affect revenue recognition?
Loyalty points providing a material right are a separate performance obligation. Allocate transaction price based on SSP adjusted for expected breakage, and recognize revenue as points are redeemed.
How do I properly validate a strategy out-of-sample?
OOS validation: set hold-out before analysis, use time-series splits, test across regimes/geographies. Nebula's momentum: IS Sharpe 1.3 → OOS 0.6 is typical decay.
How do I assess whether a company's EBIT margin is durable or about to mean-revert?
EBIT margin durability depends on whether the premium comes from structural moats vs cyclical tailwinds — triangulate with peer history, cost drivers, and capex intensity.
What key terms should I understand in a revolving credit facility?
A revolving credit facility lets the borrower draw, repay, and redraw up to a committed limit for a set term. Key provisions shape cost, flexibility, and risk.
How do you apply disruption frameworks in equity analysis?
Apply Christensen's disruption by checking for 'worse-but-different' entrants, cost structure advantage, incumbent constraints, and improvement trajectory.
What distinguishes Clayton, Gumbel, and Frank copulas and when do I use each?
Archimedean copulas are built from a single generator function phi(u), giving C(u1,u2) = phi^{-1}( phi(u1) + phi(u2) ). The family is tractable and each member captures a different tail asymmetry...
How do I analyze merger arbitrage spreads and size positions?
Spread × (365/days) = annualized. Weight by P(close); subtract break downside × P(break). Size 1-5% per deal, total gross 120-180%.
How do credit-linked notes work and what credit risk is being transferred to the investor?
A credit-linked note embeds a credit default swap in a bond structure, allowing investors to take on credit risk of a reference entity in exchange for an enhanced coupon. If the reference entity experiences a credit event, the investor loses principal proportional to the loss.
What is CROIC (Cash Return on Invested Capital) and how does it improve upon traditional ROIC?
CROIC replaces operating profit with free cash flow in the return on invested capital calculation, providing a cash-based measure of capital efficiency. It improves upon ROIC by revealing whether accounting profits translate into actual cash generation.
What is the indefinite reversal exception for deferred taxes, and when does it apply to undistributed earnings?
The indefinite reversal exception allows companies to avoid recording a DTL on undistributed foreign subsidiary earnings if management asserts those earnings will be permanently reinvested. Analysts should add the unrecognized liability back for more conservative leverage analysis.
What is the difference between FCFF and FCFE, and when would you use each one?
FCFF is cash available to all capital providers (debt and equity), while FCFE is cash available only to equity holders after debt obligations. FCFF adds back after-tax interest to net income; FCFE adds net borrowing but excludes interest. FCFE equals FCFF minus after-tax interest plus net borrowing.
How is share-based compensation expense recognized for stock options vs. RSUs?
Stock option expense is based on the grant-date fair value estimated by Black-Scholes or binomial model, recognized ratably over the vesting period. RSU expense uses the stock price at grant date. Both increase APIC on the balance sheet with no cash outflow. For graded vesting, each tranche is treated as a separate award with its own expense pattern.
How do temporary differences create deferred tax assets and liabilities?
Deferred taxes arise because accounting and tax rules recognize items in different periods. A DTL appears when taxable income will be higher in the future (e.g., accelerated tax depreciation), while a DTA appears when taxable income will be lower in the future (e.g., warranty provisions recognized on books before tax deduction).
