Own the opportunity, not the index

Index investing began as a sensible idea. When the first retail index fund was launched 50 years ago, the market was dominated by fundamental investors whose buying and selling set prices according to what businesses were worth. A passive fund could simply ride that price discovery at near-zero cost, capturing the market's return without paying for active management. For decades this worked because passive remained a minority of the market.

Passive buying works in both directions. The same mechanism that directs capital towards whatever has appreciated also forces ownership of lower-quality constituents, held not because their economics are compelling but because the market has already bid them up. Nowhere is this clearer than in the technology-heavy indices, which hold some of the century's finest businesses alongside companies whose value rests more on what AI might deliver than on what they earn today. The index cannot, and does not, tell the two apart.

In this paper "Own the Opportunity, Not the Index", I look at what happens when the same mechanism that made passive investing cheap for fifty years starts working against you. Ten stocks now make up a quarter of the MSCI World. I walk through why that concentration isn't diversification, what the dot-com index did to investors who couldn't tell the winners from the losers, and why the next decade of AI-driven returns will likely reward the investors willing to invest fundamentally, not just hold agnostic of price.
