This Is My No. 1 Recommended ETF to Buy in July

The article highlights S&P 500 concentration risk, noting tech at 38.2% of the S&P 500 vs 15.18% in the equal-weight ETF (RSP), with information tech reduced by ~23 percentage points. RSP’s top holdings are each ~0.24%–0.27% (e.g., PayPal 0.27%, Bio-Techne 0.26%), and it cites outperformance of RSP vs the S&P 500 year-to-date. It frames RSP as a complementary allocation to mitigate megacap tech concentration and suggests it could outperform into year-end.

Analysis

This is less a bullish call on passive diversification than a relative-value signal that breadth has become a factor trade. If leadership narrows again, cap-weighted benchmarks will keep outperforming because a small group can dominate index returns; if breadth persists, the marginal buyer migrates into mid-cap quality, financials, industrials, and healthcare, which should support RSP versus SPY over the next 1-3 months. The main second-order effect is valuation dispersion: megacap software/AI names can de-rate modestly even on decent earnings if the market stops paying for concentration, while lower-multiple cyclicals get multiple lift from flows rather than fundamentals.

The hidden winner is not just RSP but the ecosystem of underowned index constituents that benefit from systematic rebalancing and retail/401(k) flows: TRV, GEV, PANW, GPN/PYPL, and industrial proxies should see a mechanical bid. Conversely, ETF holders who already own QQQ-style exposure are effectively doubling down on the same names; that concentration risk becomes more visible if the next macro shock is rates-up or inflation sticky, because long-duration growth is still the most crowded factor in the market.

Contrarian view: the current breadth trade may be late if the next leg in earnings is driven by AI capex and ad-tech/platform monetization, which would re-accelerate the megacaps and pull the cap-weighted index back ahead. The thesis is falsified if NVDA/AAPL/AMZN/GOOGL/META earnings revisions keep beating while the Fed turns dovish, because that combination restores the quality-growth premium and compresses the RSP/SPY spread. That makes this a tactical trade, not a structural allocation shift.

Key Decisions for Investors

• Long RSP / short SPY for 4-8 weeks into earnings season as a breadth-rotation pair; target modest outperformance, stop if megacap tech revisits leadership and SPY regains relative strength on heavy volume.
• Alternative pair: long RSP / short QQQ to isolate concentration-risk compression; best entry is on any tech-led rally that widens the cap-weight spread, with risk defined by a dovish Fed or broad AI-driven earnings beats.
• Buy a basket of underowned cyclicals that benefit from equal-weight rebalancing pressure — TRV, GEV, GPN — and fund it by trimming an oversized megacap basket (AAPL, NVDA, META); this is a relative-weight, not absolute-alpha, trade.
• Watch the RSP/SPY relative ratio and the 10-year yield: if yields back up while breadth stays firm, the pair should work; if yields fall sharply, unwind as growth leadership likely reasserts within days to weeks.
• No aggressive options expression unless relative strength confirms: if RSP/SPY breaks to a new 3-month high, consider a small call spread on RSP versus a put spread on QQQ to keep downside defined.
