How effective are real assets (real estate, infrastructure, commodities) as an inflation hedge?
Real assets provide varying degrees of inflation protection depending on the time horizon. Commodities are the best short-term hedge, infrastructure provides strong long-term protection through contractual CPI links, and real estate works over 5+ year periods but can suffer initially from rising interest rates.
What are the key differences between the Code of Ethics, the Standards of Professional Conduct, and the Asset Manager Code?
The Code of Ethics provides aspirational principles, the Standards of Professional Conduct give specific enforceable rules, and the Asset Manager Code applies to firms on a voluntary basis. The Code and Standards are mandatory for individual CFA members; the AMC is voluntary for firms.
What are digital (binary) options, and how do their payoffs differ from standard options?
Digital or binary options pay a fixed amount if the underlying finishes above the strike (for calls) or below it (for puts), and nothing otherwise. Under BSM, a cash-or-nothing call is priced as Q times the discounted risk-neutral probability N(d2).
How is the interquartile range used to identify outliers in financial data?
The interquartile range is Q3 minus Q1, capturing the middle 50% of data. Outliers are identified using fences at Q1 minus 1.5 times IQR and Q3 plus 1.5 times IQR. This approach is more robust than standard deviation for skewed data.
How does the temporal method handle inventory carried at cost when translating foreign subsidiary statements?
Under the temporal method, inventory carried at cost is translated at the historical exchange rate from when it was purchased, not the current rate. COGS follows the same historical rate approach, matching the inventory cost flow. The remeasurement gain or loss from the temporal method goes to the income statement, unlike the all-current method which uses OCI.
How does the revaluation model under IAS 16 work for property, plant, and equipment?
Under IAS 16, PP&E can be carried at fair value with gains generally going to OCI (revaluation surplus) and losses going to P&L. However, if a prior impairment exists, a revaluation gain first reverses it through P&L. Conversely, losses first reduce any existing revaluation surplus in OCI before hitting the income statement.
How do you construct an equity collar and what are the tradeoffs?
An equity collar combines a long put (floor protection) with a short call (ceiling) around a stock position. By selling the call, the investor finances the put, creating low-cost or zero-cost downside protection at the expense of capped upside.
How do you value an option-free bond using a binomial interest rate tree?
The binomial tree approach values a bond by working backward from maturity using calibrated one-period interest rates at each node. Even for option-free bonds, the tree ensures arbitrage-free pricing consistent with the current term structure.
How do I perform a sum-of-the-parts (SOTP) valuation using segment data?
Sum-of-the-parts valuation values each business segment independently using comparable pure-play multiples, sums the results, then adjusts for unallocated corporate costs, net debt, minority interests, and excess cash to arrive at total equity value.
How do I calculate intrinsic value using the two-stage DDM?
The two-stage DDM projects dividends at a high growth rate for an initial period, then calculates a terminal value using the Gordon Growth Model at the sustainable growth rate. Sum the present values of all projected dividends and the terminal value to get intrinsic value.
How do you eliminate an upstream intercompany fixed asset sale in consolidation?
In an upstream intercompany fixed asset sale, the entire gain is eliminated in consolidation and the NCI shares in the elimination because the subsidiary is the seller. Excess depreciation is reversed each subsequent year as the gain gradually realizes.
What is component depreciation under IFRS, and how does it differ from the US GAAP approach?
Component depreciation under IFRS requires that significant parts of an asset with different useful lives be depreciated separately. This typically produces higher depreciation in early years compared to the US GAAP approach where the entire asset can be depreciated as one unit.
How does the Gordon Growth Model work for valuing a stock? What happens if g is close to r?
The Gordon Growth Model (GGM) is one of the foundational valuation tools in the CFA curriculum. The formula V_0 = D_1 / (r - g) looks simple, but the exam tests whether you truly understand its assumptions and limitations, particularly what happens when the growth rate approaches the required return.
What is the CDS basis, and why might it be negative or positive? How can traders exploit it?
The CDS basis equals CDS spread minus the bond's credit spread. A positive basis (CDS > bond spread) is driven by hedging demand and the cheapest-to-deliver option. A negative basis (CDS < bond spread) arises from counterparty risk and bond market stress. Traders exploit the negative basis by buying the bond and buying CDS protection to earn the spread differential.
How does the persistence factor work in the residual income model's continuing value, and what drives it?
The persistence factor (omega) in the residual income model ranges from 0 to 1 and determines how quickly abnormal profits decay after the forecast horizon. An omega of 0 means residual income vanishes immediately, while 1 means it persists forever. It is driven by competitive advantages like brand strength, regulatory barriers, and switching costs.
How do different commodity futures curve shapes affect investment strategy? Can you trade the curve itself?
Commodity futures curves shift dynamically between contango and backwardation based on supply-demand dynamics. Sophisticated investors trade these shifts through calendar spreads and roll yield enhancement strategies.
What is cross-validation and why is it essential for machine learning in finance?
Cross-validation divides data into multiple train/test splits to get a robust estimate of model performance. For financial time series, standard k-fold CV introduces look-ahead bias, so walk-forward validation that respects temporal ordering must be used instead.
How do ESG factors actually affect corporate financial decisions? Is it just PR or does it matter for valuation?
ESG integration in corporate finance goes beyond PR — it directly affects cost of capital, capital budgeting decisions, risk assessment, and access to funding. Companies with strong ESG profiles tend to enjoy lower WACC and more favorable financing terms.
What is a variance swap and how does it differ from a volatility swap?
A variance swap is an OTC derivative that pays the difference between realized variance and a pre-agreed strike variance over a specified period. It provides pure exposure to volatility without any directional bet on the underlying asset.
What are my duties to my employer under Standard IV? Can I prepare to leave for a competitor?
Standard IV requires loyalty to your employer but not absolute loyalty — client interests still come first. You can prepare to leave while employed but cannot solicit clients or take proprietary information before resigning.
