The method begins with a long-term strategic allocation across multiple factors rather than a concentrated bet on one style. Around that stable core, the investor makes modest tilts using several independent signals. Valuation asks how cheap a factor is relative to its own history and to other factors. Relative strength measures whether its trend is improving or deteriorating on the same time-series and cross-sectional bases. Economic-regime information assesses whether the current cycle tends to favor or hurt the factor, while dispersion indicates how rich the opportunity set may be. The signals are combined into an aggregate view rather than allowing any single indicator to dictate the allocation. This preserves diversification while creating a disciplined route to incremental active returns.
Origin
Extracted from Masters in Business, where Andrew Ang summarized research on factor timing and explained why he prefers the more measured term “tilting.”
Core principles
- 01Start with a diversified strategic factor benchmark
- 02Treat tilting as an incremental adjustment, not an all-or-nothing bet
- 03Evaluate factors against their own histories and against one another
- 04Combine valuation, trend, regime, and dispersion signals
- 05Match active tilts to the investor's risk tolerance and capabilities
How to run it
- 1
Create the strategic core
Allocate across several broad, persistent factors to establish a diversified long-term benchmark.
Pro tip Choose weights that can be held through full factor cycles.
Watch out Holding only one factor exposes the portfolio to long and painful drawdowns.
- 2
Score factor valuation
Compare each factor's current valuation with its own history and with the valuations of other factors.
Pro tip Use both time-series and cross-sectional scores.
Watch out A factor that is always relatively cheap can still be expensive compared with its own past.
- 3
Measure relative strength
Assess whether each factor's trend is rising or falling relative to its historical trends and to other factors.
Pro tip Use trend as confirmation rather than automatically buying the cheapest factor.
Watch out Cheap factors can continue deteriorating for extended periods.
- 4
Assess the economic regime
Determine whether the current stage of the economic cycle is historically supportive or adverse for each factor.
Pro tip Treat regime evidence probabilistically rather than as a precise turning-point forecast.
Watch out Economic cycles are identified imperfectly and often revised after the fact.
- 5
Measure dispersion
Evaluate the spread of opportunities within each factor to determine whether the potential reward is unusually large or limited.
Pro tip Require stronger evidence before tilting when dispersion is unremarkable.
Watch out A favorable average signal may offer little opportunity if securities are tightly clustered.
- 6
Combine and constrain the tilt
Aggregate valuation, trend, regime, and dispersion into one view, then adjust factor weights within predetermined limits.
Pro tip Document how conflicting signals affect the final tilt.
Watch out Do not let one compelling narrative override the combined evidence.
- 7
Monitor and rebalance
Refresh the signals consistently and move back toward strategic weights when the evidence weakens.
Pro tip Use scheduled reviews and explicit thresholds to reduce emotional trading.
Watch out Frequent reactions to noise can turn disciplined tilting into costly short-term timing.
In the wild
Value is historically cheap, but its relative strength remains negative, the economy is in a late-cycle regime that has hurt value firms, and dispersion is only moderate. Instead of making a concentrated value bet, the manager keeps the diversified core and applies only a small tilt until the combined evidence improves.
→ The portfolio retains potential upside without allowing valuation alone to dominate risk.
A quality factor becomes inexpensive versus its history, begins trending upward relative to other factors, and shows wide dispersion during a supportive economic regime. A portfolio manager modestly raises its weight while preserving meaningful exposure to value, momentum, size, and minimum volatility.
→ The portfolio expresses conviction while remaining diversified.
Common mistakes
Replacing diversification with prediction
The framework is intended to adjust a diversified core, not to make binary calls on a single factor.
Using only valuation
Cheapness can persist while a factor continues to trend down or faces an adverse economic regime.
Confusing tilting with rapid timing
Short-term trading increases noise and costs and abandons the strategic benchmark that anchors the method.
Is it for you?
Best for
It is best for sophisticated investors who already maintain diversified factor exposure and can implement disciplined, measured adjustments.
Not ideal for
It is not ideal for investors seeking concentrated short-term calls or those unable to tolerate periods when a tilt underperforms.
From the transcript
“Investors should start with a long term strategic combination too. Lots of factors, don't hold just one.”
“But around those strategic benchmarks you might tilt, and the paper gives a framework to think about how to do that.”
“We use all of those together and then we'll have an aggregate view on these different factors.”
