QQQ Concentration Risk

91
Since mid-2023, the gap has steadily widened - it doesn’t mean an immediate reversal, but it does mean QQQ is very top-heavy (the NDX/NDXE ratio tends to oscillate in bands; rather than, trend infinitely higher)
  • Strong NDX vs weak NDXE suggests a fragile rally
  • If mega-caps stumble, the whole index could pull back hard
  • However, if breadth improves (NDXE starts outperforming), that would strengthen the rally base

Current leadership concentration favors short-term bullish momentum (45%), but the rally is fragile, if mega-caps falter, the downside could open quickly (30%)
1. FAANG + NVDA/TSLA Leadership Persists
  • Ratio keeps rising (NDX > NDXE)
  • Leaders continue to attract flows (AI, cloud, semis).
  • QQQ pushes to new highs with narrower breadth
  • Rally vulnerable if just one or two leaders stumble (NVDA, AAPL, etc.)
  • +5–10% upside near term if momentum holds

2. Pause & Rotation (25%)
  • Ratio stalls near highs
  • Equal-weight (NDXE) starts to catch up
  • Breadth improves modestly, but QQQ as a whole chops sideways
  • QQQ consolidates in a 5%–7% band

3. Breadth Divergence Resolves Lower (30%)
  • Concentration risk unwinds
  • Leaders mean-revert (profit-taking, earnings disappointments)
  • NDX underperforms NDXE, ratio falls from highs
  • QQQ could correct −10% or more

The ratio at 2.88 is stretched relative to historical balance
  • A “reasonable” medium-term range would be closer to 2.3–2.5 (15% to 25% on percentage scale)
  • Implies QQQ pause/correction while NDXE holds steady or outperforms, or broadening participation (small/mid Nasdaq catching up)
