Leadership Broadens Beyond Mega-Cap Growth

SUMMARY

So far this week, the clearest shift within our ETF universe is a relative rotation away from growth leadership and toward a broader mix of cyclical and non-mega-cap equities. Small caps, materials, and biotech are improving versus SPY on 13-week measures, while technology, communication services, and QQQ are slipping on the same relative basis. Even so, this is still an early weekly read: much of our ETF coverage remains clustered near 13-week moving averages, including developed markets, quality, global equities, and several bond relationships, which leaves breadth and confirmation incomplete.

KEY TAKEAWAYS

- Relative leadership is widening as IJR, XLB, and IBB strengthen versus SPY while QQQ, XLK, and XLC lose ground.

- The message is rotational rather than outright directional, with no absolute price crosses across the ETF universe so far this week.

- Confirmation is limited by a dense group of ETFs still sitting near key 13-week relative inflection points, especially in international equities, factors, and fixed income.

BOTTOM LINE

Our medium-horizon read is turning less concentrated in large-cap growth leadership, but we would want a weekly close to confirm that this broadening move is durable. Until then, the rotation is notable, not fully settled.
