The yen just had one of its biggest comebacks in years thanks to government intervention, and this currency shift often punishes dollar-denominated assets as global money moves out of US markets. Meanwhile, AI chip stocks like Nvidia are showing resilienc

Verdict: Wait for FXY's RSI to cool — the paired setup is not yet live

This paired yen-strength and AI-resilience trade has genuine macro support — per the Bloomberg piece, Bessent and the Fed have helped Japan reverse months of yen losses — and Nvidia's 65.5% revenue growth with a 60.4% operating margin provides a strong fundamental anchor. But the setup is not actionable today: FXY's RSI sits at 90.1, a full 25 points above the strategy's 65 entry ceiling, meaning the larger leg of this risk-parity pair is deeply overextended relative to any condition the 44-trade backtest required. The FXY backtest's 34% win rate and 14.6% max drawdown already demand patience and discipline; chasing into an RSI of 90.1 would mean buying a condition the historical edge never validated. Meanwhile, NVDA's $0.13 cushion above its 21-day EMA leaves almost no margin for error, and the NVDA-specific backtest could not run due to incomplete data for one of its dependencies. No robust parameter setup was established by the sensitivity evaluation, so the published thresholds stand as-is. **Conviction Breakdown** - **Thesis support (65):** The dual macro narrative has fresh journalistic backing from both Bloomberg and Barron's, and Nvidia's fundamentals — $215.9B revenue, 76.3% ROE — are exceptional. The yen-intervention story is real but historically cyclical. - **Trade readiness (25):** FXY's RSI at 90.1 is 25 points past the entry ceiling; NVDA's EMA cushion is just $0.13. Neither leg offers a clean entry into the paired thesis today. - **Risk quality (50):** The risk-parity construction (67.6% FXY / 32.4% NVDA) delivers a 9.44% portfolio vol with a 1.36 diversification ratio, but the -0.05 correlation comes from a single window and the 34% win rate guarantees psychologically demanding drawdowns. - **Backtest evidence (45):** The FXY leg produced a 53% return over 24 months, but only one leg was backtested, exit fills were simulated on daily bars rather than intrabar data, and no parameter sensitivity recommendation was established. - **Fundamentals trend (80):** Nvidia's fundamentals are top-decile across nearly every metric — operating margin in the 99th percentile, free cash flow in the 99.5th — and debt-to-equity has declined from 0.53 to 0.047 over five years.

Trade now

**The short answer is: wait.** Both legs of this pair trade are flashing mixed signals against their entry conditions. For FXY, three of four entry conditions are met — ADX (14) sits at 71.8 (well above the 25 threshold), price at $57.66 is above the 21-day EMA at $56.62, and RSI at 90.1 clears the floor of 40 — but the RSI ceiling of 65 is blown through by roughly 25 points. The strategy requires RSI between 40 and 65 to confirm momentum without overbought extension, and at 90.1, FXY is deeply overextended on that measure. NVDA tells the opposite story: all four primary entry conditions are fully met, with RSI at 53.2 (comfortably inside the 40–65 band), ADX at 51.7, and price at $200.75 holding above its 21-day EMA at $200.62 by a thin margin. The contradiction matters because this is a paired thesis — the idea argues that yen strength and AI-chip resilience form a divergence trade. Entering only the NVDA leg misses the macro intent; entering FXY here means buying after the RSI has already sprinted roughly 25 points past the strategy's ceiling, into territory the backtest's 44 trades never required. The backtest produced a 53% return over 24 months on FXY with a 34.1% win rate and a 14.6% max drawdown, but those results came from setups where RSI was bounded — chasing at 90.1 abandons the disciplined entry the historical edge relied on. Concretely, "wait" means monitoring FXY for an RSI cool-down from 90.1 back below 65 while its other three conditions (ADX, price above EMA, RSI above 40) remain intact. The nearest support sits at $57.65, essentially at today's close — if price holds above the 21-day EMA ($56.62) while RSI falls into the 40–65 band, the setup re-enters its validated zone. NVDA is ready now on its own merits, but entering it solo would be a different trade than the paired thesis describes. The position sizing rule caps each leg at 20% of portfolio with a fixed-risk stop at 2.6% and a take-profit at 5.2%, giving an effective reward-to-risk of roughly 2:1 per position. No robust parameter setup was established by the sensitivity evaluation, so the published thresholds stand as-is. On the exit side, note that FXY's RSI at 90.1 already exceeds the 72 overbought-exit trigger — but the exit also requires price below the 21-day EMA and a minimum 60-bar holding period, neither of which is active.…
