FYI: Like any business, ETFs need to generate revenue to cover their costs, but plenty fail to do that. Consequently, ETF closures happen regularly. In fact, a significant percentage of ETFs are currently at risk of closure. Although investors don’t generally lose their investment in such cases, closures can be inconvenient and costly.
