Regime Trends: Breadth Broadens as Leadership Narrows

We closed April with a broad equity recovery across our ETF universe, but leadership narrowed meaningfully under the surface. 54 of 59 ETFs (92%, +23.7pp on the month) held above their 10-month moving average, while 36 of 58 (62%, -17.2pp) outperformed SPY, leaving a +29pp absolute/relative gap. We see leadership concentrated in technology, growth, emerging markets, developed ex-US and selected Asia-Pacific equities, while low-volatility, equal-weight, dividend and quality exposures, alongside China, India and healthcare, fail to confirm; Germany and parts of defensive US equity are above their moving averages but still lag the benchmark.

‍

We also saw fixed income strengthen on both axes, though the rotation is more credit-and-carry than duration-led. 15 of 17 ETFs (88%, +5.9pp on the month) held above their 10-month moving average and 10 of 16 (62%, +31.2pp) beat AGG, with EM debt, high yield, preferreds, TIPS and short-duration leading; short-duration adds stability, while Treasuries and long duration remain the rate-sensitive laggards and U.S. core aggregate sits above its moving average without relative leadership.

‍

In specialty, we saw price breadth widen but relative quality deteriorate: 13 of 15 ETFs (87%, +20.0pp on the month) held above their 10-month moving average, yet relative breadth slipped to 8 of 15 (53%, -26.7pp), with momentum, semiconductors, clean energy, gold and managed futures leading while min-vol, REITs, covered-call equity, long/short equity and crypto fail to confirm. In commodities, we see oil and broad commodities carrying the clearest multi-timescale leadership, with copper and agriculture also holding above their moving averages.

Key Takeaways

• US Technology IYW, Nasdaq 100 QQQ and Technology XLK all closed above their 10-month moving averages and above their SPY ratios' 10-month averages; XLK also posted the strongest absolute 10-month return in this alert window at 26.5%. We read that alongside cross-timescale relative leaders in emerging markets (EEM), Taiwan equity (EWT) and South Korea equity (EWY), which keeps leadership tilted toward growth and cyclical equity beta rather than defensives.

‍

• In fixed income, we see a clean duration split more than a credit warning: EM Sovereign Bonds EMB, High Yield HYG, Preferred Stock PFF, TIPS TIP and Corp. Credit VCIT all strengthened versus AGG, while government/treasury and long-duration exposure remained the relative lagging pocket. Because credit-sensitive segments are leading as duration lags, the weak spot sits in rate sensitivity rather than credit risk.

‍

• Inside specialty, Momentum Factor MTUM improved in both price and relative strength, whereas Min Volatility USMV, Real Estate VNQ, Covered Calls Nasdaq JEPQ and Long/Short Equity FTLS are recovering in price without keeping up with SPY. Biotechnology IBB adds another nuance: its ratio crossed down despite a 13.9% 10-month return, which fits fading leadership rather than outright price failure.
