Why do conglomerate mergers happen despite academic criticism?
Academic finance is skeptical of conglomerate mergers, yet they persist due to internal capital markets, tax benefits, and managerial motives.
What is the difference between horizontal and vertical mergers?
Horizontal mergers combine firms at the same stage of the value chain; vertical mergers combine firms at different stages.
How does factor-based asset allocation work?
Factor-based allocation targets systematic factors (growth, inflation, value, momentum) instead of asset classes. Offers cleaner risk decomposition but requires sophisticated tools.
How do I calculate a price-weighted index with a divisor adjustment?
Price-weighted index = sum of prices / divisor. Divisor adjusts for splits and constituent changes to maintain continuity. Higher-priced stocks have more influence regardless of market cap.
How does the endowment effect distort portfolio construction?
The endowment effect makes clients overvalue assets they already own. Accommodate by segregating legacy positions, diversifying around them, using options overlays, and gradually trimming.
What are industrial revenue bonds (IRBs)?
IRBs: muni issues debt for private company (Ridgeline Plastics $9.5M). Corporate credit is obligor; bonds are AMT private-activity, priced off BB+ rating (4.8%).
How is a target-date fund glidepath designed?
A target-date fund glidepath is a schedule of equity/fixed-income allocation versus years-to-retirement, balancing accumulation growth with preservation...
How do I aggregate convexity across a bond portfolio with multiple holdings?
Portfolio convexity is the market-value-weighted sum of bond convexities — same approach as duration, useful for estimating P&L on large parallel yield shifts.
How does litigation finance work as an alternative investment?
Litigation finance provides non-recourse capital to plaintiffs in exchange for a share of any eventual recovery. If the case loses, the funder loses its investment.
What are blue bonds and how do they work?
Blue bonds are a subset of green bonds financing ocean and marine projects. Often use blended finance with DFI guarantees and debt-for-nature swaps.
What is asset location and how does it fit into tax planning?
Asset location places tax-inefficient assets in tax-advantaged accounts and tax-efficient assets in taxable. Distinct from asset allocation. Can add 30-80 bps after-tax alpha.
How does the variance ratio test detect mean reversion or momentum?
Under a random walk, the variance of k-period returns equals k times the variance of one-period returns. The variance ratio is VR(k) = Var(r_t(k)) / (k * Var(r_t))...
When does empirical duration diverge from effective duration, and which should I use?
Effective = model-based parallel shift. Empirical = regression vs yields. HY/MBS empirical is 30-60% lower due to spread-rate negative correlation.
How does a TAC (Targeted Amortization Class) tranche differ from a PAC tranche?
A TAC tranche provides one-sided prepayment protection, shielding against faster-than-expected prepayments but not against extension risk from slower prepayments. It offers higher yield than a PAC tranche in exchange for accepting extension risk.
What is the difference between going concern value and liquidation value, and when does each matter?
Going concern value assumes continued operations and is based on future cash flows, while liquidation value assumes all assets are sold and liabilities paid. Liquidation value serves as a floor valuation and is relevant for distressed companies or asset-heavy businesses.
What are the basics of hedge accounting, and how do fair value hedges differ from cash flow hedges?
Fair value hedges protect against changes in the fair value of recognized items, with both the hedged item and hedge instrument gains/losses in P&L. Cash flow hedges protect against variability in future cash flows, with the effective portion of hedge gains/losses in OCI until the hedged transaction affects P&L. Net investment hedges protect foreign currency exposure on foreign operations, with effective portions in OCI.
How are discontinued operations presented on the income statement?
Discontinued operations are presented as a separate section below income from continuing operations, shown as a single line item net of tax. A component qualifies when it has been disposed of or classified as held for sale and represents a major line of business or geographical area. Analysts focus on continuing operations for forecasting.
How does a change in the discount rate affect both the PBO and pension expense, and why is sensitivity analysis important?
A decrease in the discount rate increases the PBO, typically increases service cost, and deteriorates funded status. The relationship is convex, meaning rate decreases have a larger impact than equivalent increases. Sensitivity disclosures help analysts stress-test pension risk.
How do you calculate the right-of-use asset at lease inception under IFRS 16?
The right-of-use asset under IFRS 16 equals the lease liability plus prepayments plus initial direct costs plus estimated restoration costs minus any lease incentives received. It is not simply the present value of lease payments.
How do I construct and interpret confidence intervals for CFA Level I?
A confidence interval = Point Estimate ± Critical Value x Standard Error. The correct interpretation is that 95% of similarly constructed intervals would contain the true population mean — not that there's a 95% probability the mean is in this specific interval.
