Key Takeaways
- • Cryptocurrency-linked ETFs dominate worst-performer lists: Bitcoin Cash ETFs posted the largest losses at -66.48% year-to-date, while Grayscale Ethereum Classic Trust ETF (ETCG) lost 55.4% in 2025, reflecting sustained weakness in digital asset markets.
- • Leveraged ETFs exhibit extreme drawdowns: Leverage Shares 2X Long BULL Daily ETF (BULG) declined -111.50% over the trailing twelve-month period, demonstrating the compounding decay risks inherent in daily-reset leveraged products.
- • Energy and small-cap dividend strategies underperformed significantly: CI Energy Giants Covered Call ETF and iShares S&P/TSX Capped Energy Index ETF ranked among the worst performers in May 2026, alongside small-cap dividend and low-volatility equity products including VictoryShares US Small Cap High Div Volatility Wtd ETF (CSB) and Invesco S&P MidCap Low Volatility ETF (XMLV).
- • Sector concentration and strategy complexity drive losses: Mid-cap and small-cap equity ETFs, particularly those employing dividend weighting, covered call overlays, or managed futures strategies (such as Simplify US Equity PLUS Managed Futures Strategy ETF—CTAP), significantly lagged broad market benchmarks.
- • Asset size and fund stability remain critical selection criteria: justETF analysis emphasizes that larger, more established ETFs with substantial assets under management (AUM) face lower liquidation risk, and that broad global diversification outperforms concentrated sector or strategy-specific exposures.
Summary
The worst-performing ETFs in 2026 reflect significant sectoral and structural vulnerabilities across multiple asset classes. Cryptocurrency-focused products have experienced the steepest declines, with Bitcoin Cash ETFs down 66.48% year-to-date and Grayscale Ethereum Classic Trust ETF (ETCG) having lost 55.4% over the prior twelve months, according to AAII and justETF data. These losses underscore persistent headwinds in digital asset valuations and the elevated volatility of crypto-tracking vehicles.
Leveraged ETFs represent an acute risk category for institutional portfolios. The Leverage Shares 2X Long BULL Daily ETF (BULG), with total net assets of only $4.78 million, posted a trailing twelve-month return of -111.50%, exemplifying the compounding decay inherent in daily-reset leveraged products. Similar distress appears across leveraged cryptocurrency products, including Leverage Shares 2X Long SATS Daily ETF (SATG) and Defiance Daily Target 2X Long RKLB and RKLX products, which have posted substantial losses during periods of underlying asset weakness.
Traditional equity strategies have also underperformed materially. Canadian energy sector ETFs—CI Energy Giants Covered Call ETF and iShares S&P/TSX Capped Energy Index ETF—ranked among the worst performers in May 2026. In the US market, dividend-weighted small-cap strategies (VictoryShares US Small Cap High Div Volatility Wtd ETF—CSB), low-volatility mid-cap products (Invesco S&P MidCap Low Volatility ETF—XMLV), and structured strategies such as Simplify US Equity PLUS Managed Futures Strategy ETF (CTAP) have lagged significantly. These underperformances suggest that factor-based tilts toward dividends, low volatility, and systematic trend-following have faced secular headwinds relative to broader equity indices.
justETF analysis reinforces that portfolio construction discipline is essential when navigating ETF selection. Fund providers recommend prioritizing broad-based global diversification—such as MSCI World exposure—over concentrated sector or strategy-specific bets. Critically, AUM size and fund inception history correlate with liquidation risk; larger, longer-established vehicles are substantially less likely to be terminated by issuers. The emphasis on physical or hybrid replication methods, rather than synthetic structures, and on UCITS compliance where applicable, further supports institutional risk management frameworks during periods of elevated ETF performance dispersion.
