How do the option Greeks (delta, gamma, vega, theta) work together in practice? I need a practical mental model.
The Greeks measure how an option's price responds to small changes in different variables. Think of them as sensitivity dials on a control panel — they don't operate in isolation but interact in critical ways for position management.
How does Standard II protect capital markets? What exactly counts as insider trading?
Standard II protects capital market integrity. The key concepts are material nonpublic information (MNPI) and the mosaic theory defense. Analysts can piece together public and non-material nonpublic information, but must not act on material nonpublic information.
Can someone break down joint, conditional, and marginal probability with a finance example?
Let's build all probability concepts using one consistent example. Marginal probability is unconditional, joint probability measures two events together, and conditional probability gives the likelihood of one event given another has occurred.
When do you use the temporal method vs the current rate method for foreign subsidiary translation?
The temporal method (remeasurement) is used when the subsidiary's functional currency equals the parent's, with gains/losses in the income statement. The current rate method (translation) is used when the functional currency is the local currency, with gains/losses in OCI as a CTA.
What are the must-know financial ratios for CFA Level I and how do I interpret them?
Financial ratios fall into four categories: liquidity (current ratio, quick ratio), solvency (debt-to-equity, interest coverage), profitability (ROE, ROA, margins), and activity (turnover ratios). DuPont analysis decomposes ROE into net margin, asset turnover, and leverage.
What are the main credit strategies in fixed income portfolio management?
Credit strategies in fixed income include credit spread duration positioning, sector rotation, security selection, credit curve strategies, and relative value trades. Each aims to generate alpha from different aspects of credit risk and spread dynamics.
How does defined benefit pension funded status appear on the balance sheet?
The balance sheet reports the funded status of the pension plan: Fair Value of Plan Assets minus PBO. If the PBO exceeds plan assets, a net pension liability is recorded. Changes each period include service cost, interest cost, actual return on assets, contributions, and benefits paid.
What are crisis alpha funds and how do they differ from other hedge funds?
Crisis alpha = returns during market stress. Funds: CTAs, tail risk, short-bias, macro. Costs carry in bull markets, pays in crashes.
What are the different types of share repurchase programs and their trade-offs?
Four main buyback methods: open-market (most common, flexible, slow), fixed-price tender (premium price, fast), Dutch auction tender (range-based price discovery), and accelerated share repurchase (immediate retirement via investment bank). Each balances speed, flexibility, cost, and signaling...
What is the proper compliance framework for an investment firm under the CFA Institute Code and Standards?
An effective compliance program covers three pillars: prevention (policies, training, pre-clearance, information barriers), detection (surveillance, reporting channels, audits), and enforcement (investigation, sanctions, regulatory reporting). The CFA exam tests both the framework design and its application to specific violations.
What are the recommended (but not required) practices under GIPS?
GIPS recommendations include independent verification, composite examination, daily valuation, additional risk measures, and supplemental analytics — optional but highly credibility-enhancing.
What calculation methods does GIPS require?
GIPS requires time-weighted returns when client controls flows, money-weighted returns when manager does, asset-weighted composites, and monthly valuation with trade-date accounting.
How does market timing theory explain equity issuance patterns?
Market timing theory: firms issue equity at high valuations, and past timing decisions leave a persistent imprint on current leverage. Baker-Wurgler found cumulative market-to-book weight explains leverage.
Can someone explain the Grinold–Kroner model step by step with numbers?
The Grinold–Kroner model breaks the expected return on equity into three intuitive building blocks: income return, earnings growth return, and repricing return. Here's a step-by-step numerical walkthrough.
What is Direct Alpha and how does it differ from PME?
Direct Alpha is annualized excess return of a PE fund vs benchmark, computed as IRR of benchmark-adjusted cash flows. More interpretable than KS-PME's multiple format...
What is negative binomial regression and when do I prefer it over Poisson?
Negative binomial regression extends Poisson by adding a dispersion parameter allowing variance to exceed mean, handling overdispersion common in financial count data...
How does adding a risk-free asset change the efficient frontier?
Adding rf transforms the efficient frontier from a curved hyperbola into a straight line. Both E[R] and standard deviation scale linearly with risky-asset weight, producing a line tangent to the old frontier...
What protections exist for whistleblowers in the finance industry?
US whistleblower protections in finance come from several statutes and regulatory programs. Dodd-Frank offers monetary awards of 10-30% of sanctions over $1M recovered...
How do I measure security selection alpha within a fixed income sector?
Selection alpha = weight x (portfolio sector return - bench sector return). Meridian's 70bps within BBB contributes 12.6bps to total active return (at 18% weight). Single-period not conclusive; requires IR > 0.5 over 3+ years for skill evidence.
What is a vector autoregression (VAR) model?
VAR is a multivariate AR where each variable depends on lags of itself and all others. No theoretical identification required. Foundation of macro policy analysis.
