Is factor timing a viable strategy?
Factor timing varies exposures to style factors based on predictive signals. Evidence is mixed — valuation spreads predict value factor returns, but most timing signals fail out-of-sample...
How is key rate PV01 computed and what does it tell me that duration doesn't?
KR01 measures dollar change for a 1bp shift at one key rate, holding others constant. Reveals curve-shape exposures that single-number duration hides.
How does importance sampling reduce variance in Monte Carlo?
Importance sampling replaces the original density with a proposal, then weights samples by p/q. Choose the proposal to put probability mass where the integrand matters most...
How do I decompose Operating Profit Margin for operational analysis?
Decompose OPM into GM, SG&A ratio, D&A, and mix effects. Driftwood's 400bps compression likely reflects arabica spike hitting GM 500bps, partially offset by SG&A leverage. Forecast margins line-by-line, not aggregate.
How do you manage a Friendly Follower client?
The Friendly Follower (FF) has moderate risk tolerance and cognitive biases — availability, recency, framing, hindsight. Example: Rodrigo Alarcón chases hot themes. Advisor approach: EDUCATE and use passive strategies — global index core, concentration caps, pre-committed rebalancing...
How is the host contract accounted for after bifurcating an embedded derivative?
After bifurcation, the host contract is accounted for as if it were a standalone instrument...
How do I bifurcate an embedded derivative from its host contract?
Bifurcation separates the embedded derivative from the host at inception...
How do you estimate cost and revenue synergies in M&A?
Cost synergies are more credible and quantifiable; revenue synergies are notoriously unreliable and should be discounted heavily.
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))...
