History
The Fama-French Factor Portfolio is based on the academic work of Eugene Fama and Kenneth French, who expanded the Capital Asset Pricing Model in the early 1990s. Their three-factor model argued that stock returns are better explained by exposure to three systematic factors: the market factor, the size factor and the value factor. Importantly, Fama and French did not publish a simple retail asset allocation. Their work is a return-explanation model, not a ready-made portfolio. This Portfolio Atlas version translates the academic idea into a practical allocation by combining broad equity market exposure with diversified size and value tilts across US and international markets.
Philosophy
The Fama-French Factor Portfolio is built on the idea that long-term equity returns may be driven by systematic factor exposures rather than stock-picking skill. The broad market sleeve captures the equity market risk premium. The small-cap value sleeves target the intersection of size and value, while large-cap and international value sleeves broaden the value exposure beyond a single segment of the market. This version is more diversified than a simple total-market-plus-small-value tilt, but it remains a practical approximation rather than an official Fama-French allocation. Its strength is clearer factor expression. Its weakness is higher tracking error, more moving parts and greater dependence on factor discipline.
