How do interest rate risk and reinvestment risk create an offsetting tradeoff for bond investors?
Interest rate risk and reinvestment risk create a natural tug-of-war for bond investors. Understanding this tradeoff is fundamental to fixed income and leads directly to the concept of immunization.
How does a limit order book work and what determines which orders get filled first?
A limit order book collects all outstanding buy and sell limit orders and matches them using price-time priority. The best-priced orders execute first, and among orders at the same price, the earliest order fills first.
Can someone break down the main hedge fund strategies and when each is used? I keep mixing them up.
Hedge fund strategies fall into four broad families based on what drives returns: equity hedge, event-driven, relative value, and global macro. Here is a decision framework with a flowchart to classify them and understand when each is used.
How do corporate issuers decide between debt and equity financing, and what's the trade-off?
Capital structure decisions are central to Corporate Issuers at CFA Level I. Three frameworks help explain how companies choose between debt and equity: Modigliani-Miller propositions, trade-off theory, and pecking order theory.
How does percentage-of-completion revenue recognition work, and when should a company use it instead of recognizing at a point in time?
Revenue recognition over time applies when a customer simultaneously receives and consumes the benefits as the seller performs. The cost-to-cost method divides costs incurred to date by total estimated costs to determine percentage complete, then multiplies by contract price.
Why do NPV and IRR sometimes give different rankings for mutually exclusive projects, and which should I trust?
NPV and IRR can produce conflicting rankings for mutually exclusive projects due to differences in project scale, cash flow timing, or reinvestment rate assumptions. When they disagree, always follow NPV because it directly measures the dollar value added to the firm.
How do I handle situations where a client pressures me to change a recommendation under Standard I(B) Independence and Objectivity?
Standard I(B) requires that your investment recommendations reflect your honest professional opinion, not the preferences of clients, issuers, or employers. The line is crossed when external pressure causes you to issue a recommendation that does not reflect your genuine analysis.
How does Chebyshev's inequality work, and when should I use it instead of the empirical rule?
Chebyshev's inequality is a distribution-free bound guaranteeing a minimum proportion of observations within k standard deviations of the mean for any distribution with finite variance. The formula is P(|X - μ| < kσ) ≥ 1 - 1/k², and it serves as a conservative floor when you cannot assume normality.
How do TIPS actually protect against inflation? I'm confused about whether the coupon or the principal adjusts.
TIPS protect against inflation by adjusting the principal value based on CPI changes, while the coupon rate remains fixed. The coupon payment equals the fixed rate applied to the growing principal, so both coupon income and principal redemption increase with inflation. At maturity, investors receive the greater of the adjusted principal or original par.
What are the different levels of ADRs and what determines which level a foreign company chooses?
ADRs come in four types: unsponsored (no company involvement, OTC only), Level I (sponsored, OTC, minimal SEC), Level II (sponsored, exchange-listed, full SEC reporting), and Level III (exchange-listed with ability to raise new capital). The key distinction is that only Level III allows capital raising.
Can someone clearly explain Type I vs Type II errors? I keep mixing them up.
This is one of the most frequently confused topics in CFA Level I Quant, so you're definitely not alone. Let me give you a framework that makes it impossible to mix them up. Type I is a false alarm — you rejected the null when it was actually true. Type II is a missed signal — you failed to reject a false null.
What are the key depreciation methods and how do impairment and revaluation differ?
Long-lived assets involve three key areas: depreciation methods (straight-line, declining balance, units-of-production), impairment testing (which differs between IFRS and US GAAP), and the revaluation model available only under IFRS.
What's the difference between contango and backwardation in commodity futures?
Contango occurs when futures prices exceed expected spot prices (upward-sloping curve), creating negative roll yield for investors. Backwardation is the opposite — futures below expected spot — generating positive roll yield. Storage costs and convenience yield drive these patterns.
Can someone explain the Modigliani-Miller propositions on capital structure?
Modigliani-Miller Proposition I says firm value is unaffected by capital structure in perfect markets. With taxes, debt creates a tax shield that increases firm value. Proposition II says cost of equity rises with leverage. The trade-off theory adds that optimal structure balances tax benefits against distress costs.
What is a covered call strategy and when would you use it?
A covered call involves owning a stock and selling a call option on it. The strategy generates income from the premium but caps your upside at the strike price. It works best when you're neutral to slightly bullish.
What's the difference between systematic and unsystematic risk, and which one can be diversified away?
Systematic risk affects the entire market and cannot be diversified away — it is measured by beta and investors are compensated for bearing it. Unsystematic risk is firm-specific and can be eliminated through diversification, so investors earn no premium for it.
How does the income approach to real estate valuation work, and what determines cap rates?
The income approach values real estate as NOI divided by the cap rate. NOI excludes debt service and depreciation. Cap rates reflect property risk — lower cap rates mean higher values and are driven by property quality, location, tenant strength, and interest rate environment.
How does sector rotation work as an investment strategy, and which sectors outperform in each business cycle phase?
Sector rotation shifts portfolio weights to sectors expected to outperform based on business cycle positioning. Consumer discretionary leads in early recovery, energy in late expansion, and utilities and healthcare in recessions.
What qualifies as material nonpublic information (MNPI) for insider trading under Standard II(A)?
Standard II(A) prohibits acting on information that is both material and nonpublic. Information is material if a reasonable investor would consider it important, and nonpublic if not yet disseminated through recognized channels.
Is a trade deficit always bad for a country? What drives it and how should investors interpret it?
A trade deficit isn't inherently bad — it depends on whether it's driven by productive investment or unsustainable consumption. The trade deficit is the mirror image of a capital account surplus, meaning foreigners are investing in the country.
