Direct Indexing: A Modern Spin on a Familiar Idea

Every few decades, the investing world rediscovers something old and convinces itself it is new. Index investing has been one of the great success stories in modern finance, and buying a low-cost fund that tracks the S&P 500 has quietly outperformed most attempts at stock picking glory. But there is a newer strategy making the rounds that puts an interesting twist on the formula, and it goes by the name of direct indexing.

To understand why it matters, it helps to rewind a bit. Mutual funds were the original way regular investors got diversification, but they came bundled with higher fees and clunky tax treatment. ETFs arrived and offered the same diversification with far less baggage, and they took over the investing world for good reason. Direct indexing takes that evolution a step further, in a somewhat unexpected direction. Instead of buying a fund that owns the stocks, the underlying stocks are purchased directly on the investor's behalf, rather than packaged into a single fund. It is a return to something more fundamental, made possible by new technology.

In practice, this means an investor holds small individual positions in the same companies that make up an index, instead of owning a single fund built around all of them. It looks and behaves almost identically to the index on the surface, but because each piece is owned directly, an investor has options an ETF holder simply does not.

The standout option is tax-loss harvesting at the stock level. Even in a strong year for the market, some individual stocks are quietly underperforming. An ETF cannot do anything about that. A directly indexed portfolio can sell off those laggards, lock in the tax loss, and replace them with similar holdings to stay aligned with the index, letting an underperformer do some good on its way out.

The other advantage is personalization. Want to skip a company for personal reasons, or already have plenty of exposure through your job? Direct indexing lets you build around it while keeping the rest of the index intact. This was once a luxury reserved for the ultra-wealthy. It has become far more accessible thanks to lower costs and better technology.

None of this means ETFs are obsolete. Direct indexing tends to make the most sense for investors with significant taxable assets and a tax situation where harvested losses are useful. For plenty of people, a simple ETF still gets the job done beautifully.
