The Three-Lens Valuation Framework assesses an asset from complementary perspectives. First, compare its current price or yield with its own history to identify unusually rich or cheap conditions. Second, compare it with other investable assets because an expensive asset may still offer better prospective returns than its alternatives. Third, evaluate whether the economic environment—including growth, inflation, corporate earnings, and earnings revisions—supports current prices. These lenses feed a forward-looking, multi-year allocation decision rather than a short-term trading signal. The mechanism helps investors distinguish absolute overvaluation from relative attractiveness and prevents a single alarming valuation statistic from dictating the portfolio. Exposure is then tilted toward assets with more favorable prospective returns while retaining caution where valuation risk is highest.
Origin
Extracted from Masters in Business, where Ranji Nagaswami explained Hirtle Callaghan's valuation discipline while comparing bonds, US equities, Europe, and emerging markets.
Core principles
- 01No asset should be valued in isolation
- 02Historical valuation provides context, not a complete answer
- 03Relative opportunity cost matters across asset classes
- 04Growth, earnings, and inflation affect sustainable returns
- 05Use valuation over long horizons rather than for short-term timing
How to run it
- 1
Establish historical context
Compare current valuation measures with the asset's long-run distribution and prior market cycles.
Pro tip Use normalized data that covers more than one economic regime.
Watch out A historical extreme does not identify when a reversal will occur.
- 2
Compare available opportunities
Measure the asset's prospective return and risk against other asset classes and regions.
Pro tip Compare equities with bonds and compare markets within each broad asset class.
Watch out Calling everything expensive does not reveal the least unattractive opportunity.
- 3
Assess economic support
Evaluate growth, inflation, earnings, and forward revisions to determine whether fundamentals justify current prices.
Pro tip Look for divergence between regions rather than relying only on global aggregates.
Watch out Strong recent returns are not evidence of strong future fundamentals.
- 4
Form a long-horizon outlook
Combine the three lenses into an expected five-to-ten-year return and risk assessment.
Pro tip Express conclusions as ranges and relative rankings rather than point forecasts.
Watch out Do not convert strategic valuation analysis into a claim about next month's market direction.
- 5
Tilt with discipline
Overweight more attractive opportunities and reduce exposure where prospective compensation is weakest.
Pro tip Make measured changes that preserve diversification.
Watch out An attractive relative valuation does not eliminate downside risk.
In the wild
Nagaswami judged risky assets fully valued and bonds particularly expensive. Historical and cross-asset comparisons favored equities over bonds, while stronger earnings revisions outside the United States favored Europe and emerging markets within equities.
→ The portfolios remained overweight equities, favored non-US markets, and stayed cautious in bonds.
An investment committee finds both US and European shares above historical averages. It compares their valuations, earnings revisions, and economic prospects rather than rejecting both markets solely because neither is cheap.
→ The committee makes a moderate regional tilt while retaining broad diversification.
Common mistakes
Using only historical averages
Historical valuation ignores the relative appeal of competing assets and the economic conditions supporting current prices.
Treating valuation as a timer
Valuation is more reliable for long-horizon expected returns than for predicting an immediate correction.
Ignoring regional fundamentals
Global market labels can hide meaningful differences in growth and earnings revisions between countries and regions.
Is it for you?
Best for
It is best for long-horizon investors making strategic allocation decisions across several asset classes and regions.
Not ideal for
It is not ideal for short-term market timing or precise forecasts of turning points.
From the transcript
“The way we think about valuation is first relative to history, but also relative to other asset classes that are available in the marketplace, and…”
“So so it's historical, it's relative to other opportunities, and it's relative to the economic environment.”
“there is a beta decision that needs to be made and that's our valuation framework.”
