Learning goals

• Decompose returns across asset classes and currencies.
• Test country, valuation and volatility assumptions.

Decision case · fictional facts

The fictional North Estuary fund estimates bond carry 4%, roll-down 0.5%, modified duration 5 and a yield rise of 0.4 percentage points. Equity inputs are dividend yield 2%, real earnings growth 2%, inflation 2% and valuation change −1%. A property has net income 8 and a 5% cap rate. FX adds a separate −3% return to an 8% local-asset return.

Component forecasts make assumptions visible

A bond horizon-return approximation combines yield income, roll-down, price change from yield/spread moves, credit loss and reinvestment. Duration estimates only small-shift first-order price risk; convexity, defaults and changing curves matter. An equity building block can combine income, real growth, inflation and valuation repricing, but overlapping components must not be counted twice. Mean reversion of valuation is an assumption to test.

Direct property return depends on income, cap rates, occupancy, operating costs and leverage. Value≈NOI/cap rate is a simplified capitalization model, not proof of a realizable transaction price. Emerging-market sovereign and equity risks include institutions, external funding, currency mismatch, governance, liquidity and data quality; a high yield can compensate for loss rather than signal mispricing.

Combine currencies and forecast risk coherently

Domestic return on a foreign investment is (1+local return)(1+FX return)−1 when FX return measures the foreign currency’s value in domestic units. Purchasing-power, interest-parity, capital-flow and valuation approaches to FX operate on different horizons and assumptions. A forward quote is not a certain future spot.

Estimate volatility using relevant samples, conditional models, implied measures and stress scenarios, recognizing nonstationarity and tail dependence. A global rebalance should follow changes in the whole expected-return/covariance/liquidity system, after costs and client constraints, rather than ranking forecasts independently.

Equity, emerging-market and property expectations

An equity building block should reconcile dividend yield, sustainable per-share real earnings growth, inflation and valuation change. For example2% income+2% real growth+3% inflation−1% multiple compression gives about6% nominal before interactions and costs. Do not add buyback yield again if its per-share growth effect is already modeled. Emerging-market equities also need minority-rights, concentration, disclosure and foreign-ownership analysis.

Property forecasts separate rent growth, occupancy, operating expenses, maintenance, leverage and cap rates. A technology shift that reduces office demand can cut occupancy even while national GDP grows. New supply and lease rollover timing can dominate broad inflation forecasts. A value increase from a lower cap rate is not the same as improved operating cash and may reverse with financing conditions.

Currency, conditional volatility and global weights

PPP-based forecasts emphasize relative price levels over long horizons; interest parity links tradable forwards to financing; valuation and balance-of-payments views address different mechanisms. None makes a forward quote a certain future spot. Forecast currency together with asset risk: a defensive foreign currency can offset equity losses in one regime and fail to do so in another.

Historical covariance estimates require relevant samples; conditional models update volatility, implied measures incorporate option-market pricing and stress tests challenge tail dependence. Compare each model’s forecast errors and liquidity implications. A global weight change should improve the constrained portfolio after currency, covariance, costs and spending needs, not merely chase the highest standalone mean.

Formula and assumptions

Bond return≈carry+roll−duration×Δy−credit loss; V≈NOI/cap; Rdom=(1+Rlocal)(1+Rfx)−1

Errors to catch

• Adding FX and local returns as if compounding never matters.
• Mistaking risky yield for expected realized return.
