Borrowing costs above 5% hit small companies hardest — they carry more debt, burn cash faster, and can't tap bond markets as cheaply as giants can. The Dow's worst start to a September since 2008 shows the seasonal and macro backdrop turning hostile at ex

Verdict: the rate trigger has fired — take the live leg, sized for the drawdown

**Verdict: the small-cap leg is live and the macro setup is real — take it as designed, not more.** The strongest point for the trade is that the thesis's rate trigger has actually fired: per Reuters (September 15, 2026) the US benchmark yield broke above 5%, and MarketWatch the same day recorded the Dow's worst September start since 2008 — exactly the environment the idea says hurts small caps, whose look-through net margin in IWM runs around -1.8% versus QQQ's covered top names at roughly 28.4%. The strongest point against is that the edge depends on a 42.3% win rate across 52 trades over 60 months, with a 12.0% worst drawdown and exit fills approximated on daily bars, so the 2.5%-stop/5%-target math is coarser than it looks, and no robust parameter setup was established. The completed backtest is encouragingly regime-consistent — the trailing 12 months returned 5.8% on 9 trades, among the stronger recent stretches — but the second leg of the pair is not ready: QQQ's 14-day ADX is 2.4 against the required 20. The verdict flips if a credible rate repricing lower emerges, which would remove the thesis's fuel, or if IWM closes below $276.04. Enter the IWM leg per the signal with sizing built for double-digit drawdowns, and let QQQ's ADX close at or above 20 before adding that leg. **Conviction breakdown:** Thesis support 72 — the 5%-plus funding-cost premise has both a rate catalyst and a weak September seasonal behind it, and the fundamentals asymmetry (IWM constituents losing money on average versus QQQ's cash-rich mega-caps) matches the thesis. Trade readiness 60 — the IWM entry rules are all met today at $285.14, but the QQQ gate (ADX at or above 20) is far away, so the full pair cannot activate. Risk quality 55 — the fixed 2.5% stop against a 5% target gives roughly 2:1 by design, with $276.04 as the invalidation, but daily-bar fill approximation and a 42.3% win rate make realized risk lumpier. Backtest evidence 62 — 28.2% over 60 months across 52 trades with consistent shorter windows, but without parameter-robustness confirmation. Fundamentals trend 58 — the margin gap favors the spread, though QQQ's top-ten concentration (44.9% of the fund) means a bond-shock repricing of long-duration tech could hurt both legs.

The IWM leg is live today. With IWM closing at $285.14, every entry condition is met: price sits above the nearest support at $276.04, the 50-day EMA ($293.75) is above price by $8.61, the 14-day ADX is 57.4 against a 20 threshold, and the 14-day RSI is 25.1, well below 50. The QQQ leg is not ready — the EMA-above-price and RSI conditions are met (EMA $710.49 versus the $704.54 close; RSI 36.7), but the 14-day ADX is only 2.4 versus the required 20, a gap of roughly 17.6 points that implies the tech leg needs a genuine trend regime to develop before triggering. Risk on the live IWM entry is tightly defined. The strategy's fixed-risk sizing uses a stop at the first support level, so a close below $276.04 invalidates the trade; the hard stop is also set at a 2.5% loss from entry (about $278 from $285.14). The take-profit fires at a 5% gain (about $299.40), and an exit also triggers if RSI rises above 65 or the position is held 60 bars. That makes the effective reward-to-risk roughly 2:1 by design. This is a completed-backtest setup, not a hypothesis: over the 60-month window the pair produced a 28.2% return across 52 trades with a 42.3% win rate and a 12.0% maximum drawdown; the trailing 12-month window shows 5.8% over 9 trades with a 44.4% win rate. Note the exit-fill caveat from the run: stops and take-profits were filled on daily trigger bars, not intrabar, so treat those statistics as coarse. What waiting means concretely: do not pre-position in QQQ — its ADX condition is the single missing gate, and adding the leg before it triggers doubles exposure without a confirmed trend. Enter IWM per the signal now, and hold QQQ until its 14-day ADX closes at or above 20 while price holds above the $701.58…
