Fundamental rebalancing replaces price as the sole determinant of portfolio weight with an economic measure such as dividends or earnings. The investor first selects a broad investable universe, weights eligible companies according to the chosen fundamental, and then periodically restores those weights. When prices rise faster than fundamentals, rebalancing trims the increasingly expensive securities; when prices lag otherwise sound fundamentals, it adds to them. The mechanism creates a systematic value discipline while retaining broad diversification and transparent rules. Because accounting measures can vary across countries, the framework may use dividends for cross-border portfolios and country-relative earnings comparisons where appropriate. Sector constraints are necessary so an apparently attractive signal does not produce a dangerous concentration.

How to run it
- 1
Select the investable universe
Start with a broad universe appropriate to the region, capitalization range, and investor mandate. Exclude securities that fail basic liquidity or investability requirements.
Pro tip Preserve broad coverage so the fundamental tilt does not become an accidental concentrated bet.
Watch out A narrow starting universe can overwhelm the intended valuation mechanism.
- 2
Choose the fundamental anchor
Select dividends, earnings, or another observable economic measure that fits the market. Prefer measures that remain comparable across the securities being ranked.
Pro tip Use dividends across countries when inconsistent accounting standards make earnings difficult to compare.
Watch out Do not treat accounting earnings from different jurisdictions as automatically equivalent.
- 3
Set transparent weights
Weight securities according to their share of the selected fundamental rather than their market capitalization. Document the calculation so it can be reproduced consistently.
Pro tip Test how the weighting rule changes valuation, quality, and sector exposure relative to the benchmark.
Watch out Fundamental weighting is not automatically diversified merely because it is rules based.
- 4
Rebalance to fundamentals
At scheduled intervals, return weights to the latest fundamental values. This trims securities whose prices have outrun their fundamentals and adds to those whose prices have lagged.
Pro tip Use a predictable schedule to remove emotion from the buy-and-sell decisions.
Watch out Rebalancing too frequently may create unnecessary turnover and taxes.
- 5
Constrain unintended risks
Measure sector, country, company, and factor concentrations before implementation. Apply limits where the fundamental signal would create exposure beyond the investor's risk budget.
Pro tip Review concentration under historical crisis scenarios, not only normal markets.
Watch out Strong value signals can cluster in a sector experiencing genuine structural distress.

Evaluate net value added
Compare the portfolio with an appropriate market-cap benchmark over full cycles. Judge success after fees, taxes, turnover, and tracking risk.
Pro tip Separate the return from intended factors from returns caused by unintended sector bets.
Watch out Short measurement windows can make a durable process appear ineffective.
In the wild
A global equity strategy uses cash dividends as the common weighting measure because reported earnings are not fully comparable across national accounting regimes. It holds a broad cross-section of dividend payers, rebalances annually, and limits each sector's weight. Companies whose prices surge without comparable dividend growth are trimmed automatically.
→ The portfolio gains a transparent value discipline without relying on cross-country earnings comparisons.
An India strategy ranks companies within the same national accounting environment and weights a broad group by earnings. Because comparisons remain country-specific, differences between national accounting systems do not distort the ranking. Sector limits prevent the cheapest industry from dominating the fund.
→ The investor receives broad local exposure with valuation sensitivity and controlled concentration.
Common mistakes
Treating cheapness as sufficient
A low valuation may reflect genuine deterioration rather than an opportunity. Pair the valuation rule with quality and concentration controls.
Ignoring sector concentration
Fundamental signals can load heavily into one troubled industry, as dividend strategies did with financial companies during the financial crisis.
Comparing incompatible earnings
Cross-country earnings figures may follow different accounting standards. Use a more objective common measure or rank companies within each country.
Is it for you?
Best for
It is best for long-term equity investors seeking systematic value or quality exposure without discretionary stock selection.
Not ideal for
It is not ideal for investors who want exact benchmark replication or short-term tactical trading.
From the transcript
“everything's market cap weighted. You need some relative discipline to rebounce back to value, help try to protect investors from bubbles and things get it…”
“the idea was to be simple, rules based, transparent but managed valuation risk for the market.”
“you can fake earnings, you can't fake dividends.”
