What are the key properties of the normal distribution I need to know for CFA Level I?
The normal distribution is bell-shaped, symmetric, and fully described by its mean and standard deviation. The 68-95-99.7 rule states that approximately 68%, 95%, and 99.7% of observations fall within 1, 2, and 3 standard deviations of the mean.
How do I identify non-recurring items and calculate adjusted earnings for analysis?
Analysts must critically evaluate non-GAAP adjusted earnings by testing frequency, magnitude, and direction of adjustments. Items that recur annually (like restructuring) or represent real costs (like stock-based compensation) should generally not be excluded from core earnings analysis.
How does the cash conversion cycle work and why is working capital management important?
The cash conversion cycle (CCC) measures how long it takes a company to convert its investment in inventory and receivables into cash, accounting for how long it takes to pay suppliers. CCC = DIO + DSO - DPO.
How do long-short equity strategies work and what are the key performance metrics?
Long-short equity takes both long positions in undervalued stocks and short positions in overvalued ones. Returns decompose into long alpha, short alpha, market beta exposure, and short rebate income. Key metrics include net exposure, gross exposure, and information ratio.
Can someone walk me through the IFRS 15 / ASC 606 five-step revenue recognition model?
The IFRS 15 / ASC 606 five-step model requires identifying the contract, performance obligations, transaction price, allocating that price based on standalone selling prices, and recognizing revenue when each obligation is satisfied — either at a point in time or over time.
How does GPT differ from BERT, and what are generative pre-trained transformers good at?
GPT is decoder-only Transformer trained autoregressively. Generates text, answers questions. Used in research summarization, coding, compliance. Beware hallucinations.
What determines the optimal dividend payout ratio?
The optimal payout balances capital needs against shareholder preferences. Frameworks include residual model, stable dividend policy, target payout (Lintner), and industry benchmarks. Determinants include growth rate, cost of retained capital, FCFE sustainability, and tax wedges...
How is maximum drawdown incorporated as a portfolio constraint?
Maximum drawdown is path-dependent, incorporated via CDaR optimization, volatility scaling, options overlays, stochastic optimization, or drawdown-aware Kelly fractions.
How does a three-year moving-average smoothing rule stabilize endowment spending?
A three-year moving-average spending rule smooths volatility but introduces lag that can create spending overhang or undershoot.
How are spending rate adjustments made when markets move dramatically?
When markets move sharply, endowment boards use collars, caps, discretionary overrides, or reopener provisions to adjust spending.
Should international equity returns be currency-hedged?
Hedging reduces volatility by 2–3 percentage points but costs 50–150bps annually. A common default is 50% hedged — balancing vol reduction against hedging cost and USD safe-haven diversification.
What is the country factor in international equity returns?
Country factor drives 30–40% of EM return variation vs 10–20% from sector factors — country dominates sector in EM. Developed markets are more integrated, so sector effects dominate there.
How does GRI differ from SASB and TCFD, and who is the audience?
GRI uses double materiality targeting broad stakeholders; SASB/TCFD (now ISSB) uses single materiality targeting investors; both can be used together.
How is a collateralized loan obligation (CLO) structured?
A CLO pools 150-300 leveraged loans and issues tranches of securities backed by the loan portfolio cash flows in a senior-to-subordinate waterfall.
What does 'crystallization' of a performance fee mean and why does frequency matter?
Crystallization is the moment when accrued performance fees become realized. Between crystallizations, fees accrue as a liability that can still reverse.
What's the difference between a soft hurdle and a hard hurdle rate?
A hurdle rate is a minimum return the fund must deliver before the manager earns any incentive fee. The 'soft vs hard' distinction is about what the incentive fee applies to.
How do I assess industry risk in corporate credit analysis?
Industry risk dimensions: cyclicality, competition, barriers, capital intensity, regulation, technology, ESG, macro. Use S&P's 1-6 IRA scale. Same Ba2 rating differs for Ridgeline Steel (weak industry) vs Riverside Food Services (stable) — industry drives bias direction...
What exactly does the Pearson correlation coefficient measure and when does it fail?
Pearson correlation captures linear association; it fails for nonlinear relationships, outliers, and heavy-tailed data — always pair it with a scatterplot.
How do I interpret the covariance between two assets?
Covariance quantifies co-movement in squared return units; divide by both standard deviations to get correlation for a dimensionless, interpretable measure.
How is free cash flow valuation different from general DCF?
DCF is the general framework; FCF valuation specifically discounts FCFF at WACC or FCFE at cost of equity. FCFF is capital-structure-neutral and preferred for changing capital structures.
