Factor Investing (Smart Beta): The ‘Moneyball’ Approach to Beating the Market
Factor Investing (Smart Beta): The ‘Moneyball’ Approach to Beating the Market
COACHING POINTS
- The Science: Just as food is made of nutrients (Proteins, Carbs, Fats), stock returns are made of “Factors.” Academic research proves that specific traits—like Value (cheapness), Momentum (trend), and Quality (profitability)—historically outperform the general market over long periods.
- The Strategy: Instead of blindly buying the whole haystack (S&P 500), Factor Investing involves “tilting” your portfolio toward stocks with these superior traits. It is the bridge between Active Stock Picking and Passive Indexing.
- The Warning: Factors are cyclical. Value can underperform Growth for a decade (like 2010-2020). To succeed, you must be a “Multi-Factor” investor, holding uncorrelated factors so that when one zigs, the other zags.
Wall Street used to sell “Alpha” (Manager Skill) for high fees. Then Eugene Fama and Kenneth French won a Nobel Prize by proving that most “Alpha” was actually just “Beta” in disguise.
Factor Investing (Smart Beta) democratizes this insight. It allows retail investors to systematically capture the excess returns that hedge funds used to charge 2% and 20% for.

The persistent drivers of return identified by academic finance.
- Value: Stocks that are cheap relative to fundamentals (Low P/E, Low P/B).
Why it works: Compensation for holding unloved/distressed companies. - Momentum: Stocks that have gone up recently tend to keep going up.
Why it works: Behavioral bias (investors herd). - Quality: Profitable companies with low debt and stable earnings.
Why it works: Investors underestimate the compoundng power of boring stability. - Size (Small Cap): Small companies tend to outperform large ones.
- Low Volatility: Boring stocks earn higher risk-adjusted returns than lottery tickets.
What-If Scenario: 20-Year Factor Performance
Comparison: S&P 500 (Market Beta) vs. Value & Momentum Factors.
| Strategy | Avg Annual Return | Behavior During Crashes |
|---|---|---|
| S&P 500 (Market) | ~7-8% | Falls with the economy. |
| Value Factor | ~9-10% | Outperforms in recovery; lags in tech bubbles. |
| Momentum Factor | ~10-11% | Crashes hard when trends reverse (“Momentum Crash”). |
Result: Over very long horizons (20+ years), Factors generate “Excess Return,” but you must endure periods of painful underperformance (Tracking Error) to get it.
Visualizing the Excess Return (The Premium)
| Factor | Historical Premium Over Market (%) |
|---|---|
| Market (Baseline) | 0.0 |
| Size (Small Cap) | +1.8 |
| Value (Cheapness) | +3.2 |
| Momentum (Trend) | +4.1 |
*Data represents long-term historical averages. Past premiums do not guarantee future premiums, but the logic (risk-based or behavioral) remains robust.
Execution Protocol
Single-Factor ETFs: Buy distinct ETFs like IJS (Small Value) or MTUM (Momentum) and rebalance yourself.
Multi-Factor ETFs: Buy an “all-in-one” fund like VFMF (Vanguard) or USMV (Low Vol) that blends factors internally to reduce turnover and taxes.
If you buy “Value” and sell it after 3 years because “it’s not working,” you will lose. Factor premiums are harvested over decades, not quarters. You are paid for the discipline to hold uncomfortable assets.
Don’t go 100% Factors. Keep 50-70% of your portfolio in a cheap Total Market Index (VTI) to ensure you capture the market return. Use Factors for the remaining 30-50% to chase the “kicker” return.
COACHING DIRECTIVE
- Do This: If you believe markets are “mostly” efficient but human behavior creates pockets of opportunity. Use it to boost returns by 1-2% long term.
- Avoid This: If you are a closet indexer who panics when your portfolio deviates from the S&P 500. Factor investing guarantees you will be different from your neighbor—sometimes better, sometimes worse.
Frequently Asked Questions
What is Smart Beta?
Smart Beta is a marketing term for Factor Investing. It refers to rules-based investment strategies that use factors (like Value or Quality) to weigh stocks, rather than traditional market-capitalization weighting.
Why doesn’t everyone do this?
Because it is hard. Factors go through ‘Drawdowns’ relative to the market. For example, Value investing underperformed Growth for almost the entire 2010s. Most investors capitulate during these bad times.
Can I lose money?
Yes. Factors increase tracking error risk. It is possible for the S&P 500 to go up 10% while your Value ETF goes up only 2%. You didn’t lose absolute money, but you lost relative to the benchmark.
