Technical vs. Fundamental Analysis
Malkiel's skeptical academic review of both major schools of stock analysis, and why he finds neither reliably beats a simple index.
Malkiel devotes a chapter each to reviewing technical analysis (chart-based reading of price patterns, covered in depth from a practitioner's perspective in this Book Club's Technical Analysis of the Financial Markets course) and fundamental analysis (valuing a company from its financial statements and business prospects, as in this Book Club's Intelligent Investor and Security Analysis courses), applying the same academic, efficient-markets skepticism to both rather than favoring one over the other.
His critique of technical analysis is the more thorough of the two: the book cites academic studies testing whether chart patterns predict future returns better than chance, generally finding they do not once transaction costs are accounted for, and argues that if a pattern reliably worked, its exploitation by enough traders would itself eliminate the edge — a direct application of the efficient market argument from the first chapter of this course. Fundamental analysis fares somewhat better in his assessment, since it at least prices in real information about a business, but he's still skeptical that the average investor, or even the average professional analyst, can do it well enough and consistently enough to beat a low-cost index after fees and trading costs.
| School | Malkiel's core critique |
|---|---|
| Technical analysis | If a chart pattern reliably worked, its own exploitation would eliminate the edge |
| Fundamental analysis | Prices in real information, but consistently doing it better than a competitive market is very hard |
Malkiel frames the whole debate through two competing older theories of how stock prices are actually determined: "firm-foundation" theory, which holds that every security has an underlying intrinsic value that can be calculated from its fundamentals (dividends, earnings growth, interest rates), with price eventually converging to it; and "castle-in-the-air" theory, associated with Keynes, which holds that a security is worth whatever the next buyer will pay for it, making psychology and crowd expectation the real driver of price, at least over shorter periods. His conclusion is that both contain real truth — fundamentals matter over long periods, psychology dominates over shorter ones — which is itself part of why he's skeptical either school can be applied reliably enough by an individual investor to consistently beat a diversified index.
- Malkiel applies the same efficient-markets skepticism to both technical and fundamental analysis, rather than favoring one.
- His critique of technical analysis: if a pattern reliably worked, its own exploitation by enough traders would eliminate the edge it offered.
- The firm-foundation vs. castle-in-the-air framing holds that both fundamentals and crowd psychology genuinely matter — fundamentals more over long periods, psychology more over shorter ones.
