Investors today have more tools than at any point in history: thousands of exchange-traded funds, fractional shares, income-engineered products and real-time data on every screen. Yet one veteran of the hedge fund world argues the most important variable has not changed at all. The human wiring that drives investor decisions is the same as it was three decades ago, and for long-term savers, that is the part of the story that matters most.
Victor Haghani, founder and chief investment officer of Elm Wealth and a founding partner of Long-Term Capital Management, put it bluntly in a recent CNBC ETF Edge interview. He is not convinced investors are much more sophisticated than they were 30 years ago. People remain subject to extrapolation bias, the habit of assuming that whatever has happened lately will keep happening. After a long run of strong returns in a hot theme, that instinct is exactly what pulls capital into the most crowded corner of the market at the worst possible moment.
His second point is about who sits on the other side of the trade. Firms like Citadel, Jane Street and Hudson River Trading, he notes, are making money every single day, in an environment that is rich with opportunity if you can afford to spend a billion dollars a year on technology. A retail investor hunting for an edge from a home computer should assume the counterparty is a professional with far better data, faster execution and lower costs. In his words, it probably is not going to end well. His conclusion: individuals are best served with at least some exposure to broad, low-cost index funds.
The other view deserves a fair hearing. Valerie Grimba, director of global ETF strategy at RBC Capital Markets, argues that more choice is ultimately a good thing. In her view, funds holding 10 to 15 stocks can let investors participate in a theme without having to identify its eventual biggest winner, and derivative-based products can generate income in different ways. But even she attaches a condition that echoes Haghani's caution: investors should understand exactly what they own and the trade-offs involved, well enough to explain the fund to a friend.
So what for long-term investors? The takeaway is not that every investor must own only an index fund. It is that the burden of proof sits with any strategy that is more complicated, more expensive or more fashionable than the plain alternative. Before adding a concentrated theme fund, a leveraged product or an options-income wrapper, ask three questions: what exactly do I own, what does it cost me every year, and what is my edge against professionals who do this full time? If the honest answer to the last one is none, a diversified, low-cost core holding is not a boring compromise. It is the part of the portfolio most likely to compound quietly while recent winners come and go. The investors who do best over decades are usually the ones who design around their own biases rather than pretend to be immune to them.
