Portfolio Fit Notes

A broad-market fund can behave very differently from a sector, thematic, income, commodity, or crypto asset product. When two ETFs look similar at first glance, compare the index methodology, constituent rules, turnover, option overlay, bond duration, or commodity structure behind the ticker.
