An element in the Fama/French stock price model is small minus big. Returns on investment portfolios can be explained in part by SMBs, among other things. Depending on a company's market capitalisation, this impact is also referred to as the "small firm effect" or the "size effect.

Understanding Small Minus Big

Excess return from tiny vs large market capitalization firms is known as the "little minus big" rule. As an extension of the Capital Asset Pricing Model, Fama/French three-factor modelling (CAPM). There is just one aspect of CAPM: the market's performance as a whole. The market factor refers to this element. The CAPM explains the returns of a portfolio in terms of the risk it carries compared to the market. In other words, according to CAPM, a portfolio's success is mostly influenced by the stock market's overall performance.

To the CAPM model, Fama/Three-Factor adds two more elements. The concept states that in addition to market performance, a portfolio's performance is influenced by two other elements. If a portfolio contains more small-cap firms, it is expected to do better over time than a larger portfolio of larger companies.

Stock Return Importance

The Fama-French three-factor model is one of the most commonly used techniques for describing stock returns. Thus we'll briefly explain why this topic is significant. The stock values that fluctuate over time are presumably familiar to you due to popular culture. They keep track of the price movements regularly.

This is a common blunder, and I'll explain why. A common way for stocks to reward their owners is through dividends, payments from a company's profits to its shareholders. The company's board of directors oversees the distribution of dividends, which can be made in stock, shares, cash, or any combination thereof.

Companies and investment funds are well-known for distributing profits to their loyal shareholders. We need to consider both capital gains and dividends to get a complete picture of how equities perform over time. If you want to compare the performance of stocks owned for different periods, this is a great tool.

What Can Investors Learn from Fama and French's Three-Factor Model?

The Fama and French Three-Factor Model emphasise that investors must be prepared to withstand short-term increases in volatility and periods of underperformance. In the long run, investors with a 15-year time horizon will be compensated for short-term losses. Investors may customise their portfolios to earn an average anticipated return based on the relative risks they incur, given that the model can explain up to 95 per cent of the return in a diversified stock portfolio.

Five-Factor Model by Fama and French

In recent years, researchers have added additional components to the Three-Factor model. Momentum, quality and minimal volatility are just a few examples. In 2014, Fama and French revised their model to add five variables. The new model includes, in addition to the original three elements, the idea that firms reporting larger future earnings have better stock market returns, a factor known as profitability.

"Investment" refers to the notion of internal investment and returns, which suggests that corporations that direct profits into large expansion projects are more likely to lose money in the stock market.

Model: What Are The Three Factors?

Size, book-to-market valuations, and excess market returns are all components in Fama and French's model. SMB (small minus large), HML (high minus low), and the portfolio return minus the risk-free rate are the three parameters considered. Small and medium-sized businesses (SMB) and value stocks (HML) yield larger returns than the market as a whole, according to the SMB index and HML index.

Small Minus Big (SMB) vs High Minus Low (HML) (HML)

When using the 3-Factor approach, High Minus Low is the final variable to be considered (HML). Companies with a high book-to-market value ratio are "high." A company with a low book value-to-market value ratio is "low." Companies with a high book-to-market ratio are sometimes referred to as "value stocks," This element is also known as "value vs growth."

Low market-to-book value companies are sometimes referred to as "growth stocks." According to studies, value companies beat growth in the long term. A value-oriented portfolio's long-term performance should be superior to that of a growth-oriented portfolio.

Considerations

A portfolio manager's returns can be evaluated using the Fama/French model. However, the portfolio manager's contribution is negligible when all three elements can be accounted for in its performance.

If the three elements can account for the portfolio's performance, then the manager's competence is not responsible for any part of the portfolio's success. A skilled portfolio manager should contribute to a portfolio's success by choosing strong stocks. Alpha" refers to its superiority.
