Evaluating New Investment Products
Malkiel's skeptical framework for new financial products and strategies that promise to beat simple indexing.
The financial industry continually produces new products — smart-beta funds, actively managed ETFs, structured products, and whatever the current decade's trend happens to be — each typically marketed with a story for why it can beat a simple broad index. Malkiel applies the same skeptical framework from earlier in the book to each new product as it appears: what specific, durable edge does this claim to offer, is that edge consistent with how competitive and information-efficient markets actually behave, and critically, what does it actually cost compared to a plain index fund.
His recurring finding across product categories is that many of these offerings either repackage market-beta exposure at a higher fee than a plain index fund charges for the same underlying exposure, or add genuine complexity and risk in exchange for a marketing story that doesn't hold up to the same scrutiny the book already applied to active stock-picking and market-timing earlier — the burden of proof, in his framework, should always sit with the new product to justify its extra cost or complexity, not with the simple index default.
Distilled across the specific products the book critiques, a consistent set of questions emerges for evaluating any new investment offering: does it charge meaningfully more than a comparable plain index fund; is its claimed edge backed by evidence beyond the marketing material itself; does it add complexity or illiquidity an investor may not fully understand; and would a skeptical, efficient-markets-minded reader expect that specific edge to survive once enough other investors also try to exploit it. A product that fails several of these checks is treated as a weak candidate to displace a core index holding, whatever story accompanies it.
- New financial products should be evaluated against the same efficient-markets skepticism the book applies to active stock-picking and market-timing.
- A common pattern the book identifies is repackaging ordinary market exposure at a higher fee than a plain index fund charges for similar exposure.
- The burden of proof should sit with any new product to justify its extra cost or complexity over a simple index default, not the other way around.
