4. The Nikkei Semiconductor Index Rebalance, Kioxia, Nikkei Volatility Hedge
- Kioxia set for inclusion in the Nikkei Semiconductor Index next week, alongside JX Advanced Metals, less than one day’s average daily volume in passive inflow at the close.
- Kioxia’s Q2 2025 results show an accelerating QoQ recovery and solid Q3 2025 forecasts, driven by high demand from data center and smart device products, confirming effective business structure reform.

5. Asian Stocks Tactical Outlook (Week Nov 17 – Nov 21)
- A tactical snapshot of the Asian indices and stocks we cover.
- Multiple Asian stocks we track are flashing oversold signals—creating tactical long setups worth considerin.
- We find no overbought stocks or indices in Asia at present. US equities show the same pattern, indicating a synchronized global market pullback
6. Nikkei 225 (NKY) Tactical Outlook After Japan’s Economy Contracts on Tariff Hit
- Japan’s Q3 GDP shrank 1.8% vs forecast 2.5% (annualised), while consumption slowed to 0.1%. This is the first contraction in six quarter.
- The cause is the drop in exports in the face of U.S. tariffs, automakers in particular plummeted, following a period of hiking exports before tariffs came into effect.
- We’ve consistently flagged the Nikkei 225 (NKY INDEX) as overbought. This tactical short-term analysis pinpoints critical support (and resistance, but we think the index may fall).
7. BYD (1211 HK): Leverage Softening Fundamentals with Short Calls
- Bearish fundamental views are strengthening: Recent Smartkarma Insights argue BYD (1211 HK) is overvalued, with slowing sales growth and valuation multiples pointing to limited upside.

- Strike and expiry selection matter: Short-dated December options provide the best liquidity, while higher strikes balance premium income with room for near-term upside.
8. 4-Hour Contagion: NVIDIA Q3, Advantest, the AI Flow Footprint on the Global Synchronized Selloff
- Performance was in line with estimates, with total revenue of $57.01B and an expanding Non-GAAP Gross Margin of 73.6%. Management issued robust Q4 revenue guidance of $65B.
- Despite strong fundamentals, the stock’s muted reaction and subsequent slide highlight the risk of unusual, synchronized cross-asset market drops, signaling a need to examine, and hedge against potential systemic vulnerability.
- The synchronized cross-asset market drop on November 20, lacking a clear catalyst, suggests hidden systemic risk driven in part by algorithmic positioning.
