Stock exchange-traded funds, or equity ETFs, are often low-cost instruments for investors to track popular indexes or leverage experienced manager choices to beat the market. The best ones serve as low-cost building blocks in a portfolio, and unlike open-end mutual funds, all ETFs are traded throughout the day on an exchange.
In May 2026, the worst-performing stock ETFs included Indonesia equity fund Xtrackers MSCI Indonesia Swap UCITS ETF KJ7 and equity natural resources fund HANetf ICAV - Sprott Uranium Miners UCITS ETF URNM. Data in this article is sourced from Morningstar Direct.
Screening for the Worst-Performing ETFs
When evaluating ETFs, investors should focus on long-term returns across multiple years and market cycles. However, short-term returns can provide valuable information about biases within strategies.
To find the month’s worst-performing stock ETFs, we screened those in Morningstar’s equity, allocation, or fixed-income categories that are available in Norway. We excluded ETFs with less than USD 25 million (€21.5 million) in total assets. We also excluded funds that fall into Morningstar’s “trading” categories, as these funds are designed for active traders and are not suitable for long-term investors.

What Are ETFs?
Exchange-traded funds are investments that trade throughout the day on stock exchanges, much like individual stocks. They differ from traditional mutual funds—known as open-end funds—which can only be bought or sold at a single price each day. Historically, ETFs have tracked indexes, but in recent years, more ETFs have been actively managed. ETFs cover a range of asset classes, including stocks, bonds, commodities, and most recently cryptocurrency.
