How does a leveraged buyout (LBO) model work, and what drives equity returns for the sponsor?
A leveraged buyout uses primarily debt financing to acquire a company. Sponsor returns come from three levers: EBITDA growth, debt paydown from the company's own cash flows, and potential multiple expansion at exit.
What drives credit spreads on corporate bonds and how do they change through the economic cycle?
Credit spreads represent the additional yield investors demand over risk-free rates to compensate for default risk, credit uncertainty, and illiquidity. They have three components: expected loss, credit risk premium, and liquidity premium, and they fluctuate dramatically through the economic cycle.
How do you value a callable bond and what's the relationship between OAS and the call option?
Callable bonds give the issuer the right to redeem the bond before maturity. The fundamental relationship is: Value(callable) = Value(option-free) - Value(call option). OAS removes the option cost from the Z-spread, leaving only credit and liquidity compensation.
How do you derive a justified P/E ratio from fundamentals, and how is it different from a trailing P/E?
A justified P/E ratio is derived from the Gordon Growth Model: justified leading P/E = (1 - b) / (r - g), where b is retention, r is required return, and g is growth. It tells you what P/E a stock should trade at given its fundamentals, and comparing it to the actual P/E reveals potential mispricing.
How does sum-of-the-parts valuation work and why do conglomerates trade at a discount?
Sum-of-the-parts valuation values each business segment separately using appropriate peer multiples, then sums them and subtracts net debt. Conglomerates typically trade 10-15% below SOTP value due to capital allocation inefficiency, complexity, management dilution, and investor preference for pure-play companies.
How do you assess receivables quality using the allowance for doubtful accounts and turnover ratios?
Receivables quality is assessed by analyzing receivables turnover, DSO, and the allowance for doubtful accounts relative to gross receivables. Key red flags include DSO increasing over time, A/R growing faster than revenue, and the allowance ratio declining despite receivables growth.
FIFO vs. weighted average cost: how do they affect COGS, inventory, and taxes when prices are rising?
Under FIFO, the oldest costs flow to COGS while the newest remain in ending inventory. Under weighted average, all costs are blended. When prices are rising, FIFO produces lower COGS, higher ending inventory, and higher net income compared to weighted average.
How does goodwill impairment work under the acquisition method?
Goodwill arises when the purchase price exceeds the fair value of net identifiable assets in an acquisition. Impairment testing compares the fair value of the reporting unit to its carrying amount, and any shortfall (up to the goodwill balance) is recognized as an impairment loss.
What is the Permanent Portfolio and how does it differ from All-Weather?
Permanent Portfolio: equal 25% in stocks, long bonds, gold, cash. Unleveraged, simple, rebalance yearly. ~7.5% returns, smaller drawdowns than 60/40.
How do I calculate the breakeven inflation rate from nominal and TIPS yields?
BEI ≈ Nominal yield minus Real yield. Exact: (1+Nom)/(1+Real) - 1. BEI contains expected inflation PLUS inflation risk premium MINUS TIPS liquidity premium. In normal times these risk/liquidity adjustments roughly offset, so BEI approximates market-implied inflation expectations...
How does immunization work for fixed-income portfolios and what are the conditions for it to succeed?
Immunization structures a fixed-income portfolio so that price risk and reinvestment risk offset each other, ensuring the portfolio can meet a future liability regardless of rate changes. Success requires matching duration, maintaining sufficient present value, minimizing excess convexity, and regular rebalancing.
How do I calculate after-tax return on a taxable investment portfolio?
After-tax return accounts for the drag taxes impose on pre-tax returns, differentiating by income type because different tax rates apply to ordinary income, qualified dividends, and capital gains...
Why do bond indices have higher turnover than equity indices?
Bond indices turn over 15-25% annually due to maturities, continuous new issuance, and credit migration (fallen angels/rising stars). Drives higher transaction costs and wider tracking error for passive bond funds.
What exactly is the Capital Market Expectations (CME) framework and why does it matter for asset allocation?
Capital Market Expectations (CME) refer to the set of projected risk and return characteristics for various asset classes that an investor uses as inputs for portfolio construction. The framework has several key elements including setting the horizon, ensuring cross-sectional and intertemporal consistency, and conducting thorough macro analysis.
What's the difference between net-of-fees and gross returns in GIPS reporting?
Gross-of-fees return measures pure investment performance before management fees; net-of-fees reflects investor experience after fees. GIPS requires clear disclosure of which is reported...
How does the CART algorithm build regression trees?
CART builds regression trees by recursively selecting splits that maximize RSS reduction, stopping based on depth or sample criteria, then pruning via cross-validation...
How do I analyze isoquants and indifference curves in portfolio selection?
Indifference curves represent constant-utility combinations of risk and return. Optimal portfolio is the tangency point between the highest indifference curve and the feasible set...
What are GIPS rules for including portfolios in composites?
All actual fee-paying discretionary portfolios must be in composites. Non-discretionary excluded. Minimum asset thresholds allowed. Terminated portfolios remain in history. New portfolios added timely per policy...
How do I evaluate sector rotation strategies in fixed income?
Cobalt's IG→HY rotation (20pt shift) captures +40bps carry but risks -70bps per 100bps widening. Evaluate regime-shift risk, sub-sector selection within HY, exit triggers, and historical Sharpe 0.5-0.8 on similar rotation strategies.
What is the difference between absolute and relative return objectives?
Absolute return: stand-alone target (e.g. 6%). Relative return: benchmark plus alpha (e.g. S&P + 150 bps). Individuals use absolute; active managers use relative; many funds use both at different levels.
