Strategy overview

The small cap effect is the long-observed tendency for smaller companies to have delivered higher long-run returns than larger ones, compensated by higher volatility. What distinguishes this entry is where the claim comes from: within the first seconds, the source video anchors it to the Fama-French three-factor model — an academic framework, not a chart pattern — which places the idea in a different category from most setups catalogued here.

That provenance changes what the "strategy" actually consists of. There is no entry trigger to inspect; the decisions that determine the outcome are a universe definition (what counts as small), a sorting rule (the video's comparison runs small cap value against small cap growth), a rebalancing cadence, and a holding horizon. Quantified Strategies closes on a long-term investment growth example, which makes compounding over decades the unit of measurement rather than trade-by-trade performance. A factor tested this way describes the classification scheme as much as it describes the market.

Two caveats travel with any published factor premium and are worth holding while watching. First, the effect was documented in academic literature and has been public for decades, so the live question is post-publication persistence rather than historical existence. Second, a basket of small companies carries implementation costs — liquidity, spreads, capacity — that a broad index backtest does not automatically charge. No mechanical rules have been extracted for this entry; it is best read as a backtest of an academic effect, and the source video is the primary reference.

Frequently asked questions

What is the small cap effect in investing?

It is the historically observed tendency for smaller-capitalization companies to produce higher long-run returns than large-cap companies, accompanied by greater volatility and deeper drawdowns. It is usually treated as a factor premium rather than a timing signal.

How does the Fama-French three-factor model relate to the small cap effect?

The three-factor model, referenced early in the source video, extends the classic market-risk model by adding a size factor and a value factor. The size factor is the formal expression of the small cap effect, which is why the concept is normally discussed in a portfolio and academic context rather than a chart-setup one.

What is the difference between small cap value and small cap growth?

Both are small companies, separated by valuation: value names trade at lower prices relative to fundamentals like book value or earnings, growth names at higher ones. The source video runs its historical comparison along exactly this split, which is why the sorting rule matters as much as the size filter.

Is the small cap effect something you trade or something you hold?

It is generally framed as a long-horizon allocation premise rather than a trade signal — the video's closing example measures results as multi-year compounding. That also means evaluating it requires long historical samples and attention to how the stock universe was built, since index construction and survivorship choices can move the result.
