Russian-linked exchange-traded funds are some of the worst-performing equity ETFs so far this year, as Russia continues its invasion on Ukraine. The funds have become so insignificant that Morningstar has dropped coverage.

“We’re committed to covering those funds that are most relevant to investors and that hold a significant portion of industry assets,” Morningstar said.

But the Russian ETFs are not the only ones performing poorly. Some of the biggest losers are crypto- and technology-linked products. Special purpose acquisition company (SPACs) and cannabis investments are also among the worst performers.

Equity ETFs are the most common type of exchange-traded funds that enable you to own part of hundreds or even thousands of companies in a single trade. 

Here is Morningstar's list of the 10 equity ETFs with the worst performance so far this year, as of June 13.
