Index and Sector ETFs

About Index and Sector ETFs

This is where most people should start and where most people should probably stop. A broad index fund at a few basis points has beaten the large majority of professional active managers over any long period, and the reason is arithmetic rather than skill: costs compound against you exactly the way returns compound for you.

Weighting matters more than the name on the front. Most index funds weight by market value, which means the largest companies dominate the return and the fund quietly concentrates as they grow. That has been enormously profitable and it also means a standard large-cap index fund is far less diversified than its holdings count suggests. Equal-weight versions of the same index own the same companies in the same proportions and behave differently enough to be a separate decision.

Sector and country funds are a different activity. Those are bets, not diversification, and buying one after it has already run is the most common way retail investors underperform the index they were trying to beat. This group also collects anything that is not a bond, commodity, leveraged or inverse fund, including actively managed portfolios and single-asset trusts, so read the holdings rather than the category.
