Key takeaways
Key Takeaways
The dominant transmission mechanism is an abrupt semiconductor supply shock colliding with an already expensive growth and AI complex. In this setup, hardware, hyperscalers, and chip-linked equities absorb the largest drawdowns, while defensives, energy, and select alternative stores of value hold up better on a relative basis.
Semiconductor supply shock
Advanced chips and packaging capacity disappear for Western buyers, disrupting AI servers, consumer electronics, autos, and industrial systems almost immediately.
Sanctions and trade freeze
US and allied sanctions sever trade, capital, and payment links with China, creating second-order stress across sourcing, logistics, and corporate cash flows.
Defensive rotation
Investors rotate away from high-duration growth into more defensive sectors, cash-flow stability, and assets perceived as safer during geopolitical stress.
Valuation reset
Higher discount rates, lower growth assumptions, and earnings downgrades force a broad repricing across the semiconductor and mega-cap tech value chain.

How this scenario flows through to portfolio positions
Under Pressure
Mega-cap technology
HighNames tied to AI infrastructure, cloud expansion, and premium consumer electronics face direct chip shortages plus aggressive valuation compression.
Semiconductor-linked supply chains
HighRevenue recognition, production volumes, and capex plans are disrupted by lost access to advanced foundry capacity and packaging bottlenecks.
Consumer cyclicals and e-commerce
MedWeaker demand, higher sourcing friction, and trade disruption pressure margins and inventory turns.
China-sensitive cyclicals
HighIndustrial and commodity businesses exposed to Chinese demand face slower activity and weaker end-market pricing under sanctions and decoupling.
More Resilient
Defensive healthcare
StrongDemand tends to be less cyclical, helping earnings hold up better than growth sectors during recessionary shocks.
Integrated energy
StrongGeopolitical risk premiums and tighter energy markets can partly offset weaker global growth.
Large diversified banks
ModCredit costs rise, but stronger trading activity and potential deposit inflows can cushion the hit relative to technology equities.
Alternative stores of value
ModAssets such as Bitcoin may initially sell off with risk assets but can recover if fragmentation strengthens demand for non-sovereign alternatives.

| Holding | Weight | Scenario impact | Contribution | Key exposure |
|---|---|---|---|---|
AAPL Apple Inc. | 13% | -59% | -7.7% | Apple screens as the most overvalued large-cap here: the reverse DCF base fair value is just $22.34 versus $230.00, falling to $17.09 in the Taiwan-invasion scenario as WACC rises from 16.0% to 18.0%, implying downside of 92.6% to current price. The transmission is direct and severe: a semiconductor famine constrains iPhone, Mac, iPad and wearables shipments, while a China/Taiwan rupture also disrupts Apple’s assembly ecosystem and raises logistics and working-capital friction, compounding a recession-driven hit to upgrade demand. Against the historical blend of the 2020-2021 electronics shortage and 2022 mega-cap tech derating, the scenario path to $94.07 in 12 months is consistent with heavy earnings impairment plus multiple compression from today’s 30.8x P/E and 3.0% FCF yield. |
MSFT Microsoft Corporation | 13% | -43% | -5.6% | Microsoft’s reverse DCF base fair value of $182.63 already sits 57.5% below the $430.00 stock price, and the scenario cuts that to $147.42 as WACC moves from 16.0% to 18.1% and implied FCF growth falls from 25.0% to 22.9%. The key transmission channel is Taiwan-linked AI infrastructure scarcity: Azure demand already exceeds supply, and in this shock backlog turns into delayed revenue as advanced GPUs and networking silicon become unavailable, while weaker enterprise spending adds a second drag. Relative to the 2022 quality-growth software correction and prior cloud capacity bottlenecks, the 12-month scenario target of $246.17 reflects both slower AI monetization and de-rating from a still-rich 33.0x P/E and 2.3% FCF yield. |
NVDA NVIDIA Corporation | 12% | -53% | -6.4% | NVIDIA has the clearest direct exposure to the Taiwan node: the stock at $138.00 compares with a reverse DCF base fair value of $47.81 and a scenario fair value of just $36.28, with WACC rising from 16.0% to 18.4% and implied FCF growth slipping from 25.0% to 23.0%. The transmission is immediate through lost wafer starts, advanced packaging and system assembly capacity, which halts hyperscaler deployments and delays recognized revenue across the AI stack; sanctions then remove any residual China offset. Versus the closest analogue of a blend between the dot-com semiconductor unwind, 2022 high-duration derating and isolated COVID fab disruptions, the 12-month target of $64.59 still looks plausible given the stock’s 46.6x P/E and 1.7% FCF yield. |
GOOGL Alphabet Inc. | 10% | -36% | -3.6% | Alphabet is less directly exposed than hardware and AI-chip names, but the DCF still shows material downside: base fair value is $85.60 versus $175.00, falling to $73.79 in scenario as WACC rises from 16.0% to 17.9% and the implied growth view drops from 22.5% to 18.1%. The main transmission is cyclical rather than physical: a global recession weakens ad budgets across Search and YouTube, while Google Cloud AI monetization is delayed by chip shortages, though the lower starting multiple offers some cushion. Relative to the 2008-2009 advertising recession and 2022 digital ad reset, the 12-month scenario target of $112.24 suggests less severe de-rating than peers because the stock starts at only 16.0x P/E and a 3.5% FCF yield. |
AMZN Amazon.com Inc. | 10% | -50% | -5.0% | Amazon’s valuation leaves little room for a combined chip and trade shock: the DCF base fair value is $52.39 against a $195.00 share price, dropping to $43.40 in scenario as WACC increases from 16.0% to 18.2%, implying 77.7% downside. The transmission is twofold: AWS AI expansion is throttled by advanced-chip scarcity, while a US-China trade and financial freeze disrupts retail sourcing, seller economics and consumer demand across the commerce platform. In the context of the 2022 Amazon de-rating plus 2020-2021 supply-chain stress, the 12-month target of $97.86 reflects both earnings pressure and sharp multiple compression from 35.3x P/E and a 1.3% FCF yield. |
JPM JPMorgan Chase & Co. | 11% | -29% | -3.2% | JPMorgan is one of the more resilient names in the set, but the residual income valuation still points to downside, with base fair value at $148.40 versus $240.00 and scenario fair value at $129.58 as WACC rises from 16.0% to 17.4%. The transmission is macro-credit rather than semiconductor-specific: a recession raises provisioning across consumer, card and corporate books, while investment banking and loan demand soften, partly offset by stronger trading and likely flight-to-quality deposit inflows. Relative to the 2020 COVID bank drawdown and 2023 money-center outperformance, the 12-month target of $171.23 implies a more moderate re-rating than tech because the stock starts at 12.0x P/E and is not priced for aggressive growth. |
XOM Exxon Mobil Corporation | 7% | -31% | -2.2% | Exxon is unusual in that the scenario fair value of $41.40 is above the base fair value of $30.02, even though both remain well below the current $115.00 price, reflecting a geopolitical energy-risk premium that partly offsets a higher WACC of 17.2% versus 16.0%. The transmission channel is favorable relative earnings revision: sanctions and war elevate oil and LNG prices, upstream realizations improve, and the integrated model can capture downstream volatility even as weaker GDP softens some demand. Using the 2022 Russia-Ukraine shock as the closest analogue, the 12-month target of $79.81 suggests XOM should outperform growth equities on a relative basis given its 5.2% FCF yield and low leverage, even if absolute valuation still looks stretched versus NAV. |
UNH UnitedHealth Group | 8% | -21% | -1.7% | UnitedHealth is defensively positioned but not immune: comps-based fair value is $388.34 versus $575.00, edging down to $367.74 in scenario as WACC rises from 16.0% to 17.3%, implying a smaller 36.0% downside than most equities in this shock set. The transmission is indirect, with healthcare demand staying relatively stable while medical-cost inflation and existing operating pressure weigh on margins, and defensive rotation supports relative performance versus high-duration tech. Against the historical analogue of managed-care defensiveness in 2008-2009 and inflation pressure in 2022, the 12-month target of $456.13 fits a market that rewards stability but still de-rates an expensive stock at 43.5x P/E. |
 BHP BHP Group | 8% | -49% | -3.9% | BHP’s NAV-based valuation is very low relative to the market price, with base fair value at $7.26 versus $48.00 and scenario fair value at $5.99 as WACC rises from 16.0% to 17.2%, implying 87.5% downside on the model. The transmission is mainly through China-linked industrial demand destruction: sanctions and decoupling weaken steel activity and iron ore pricing, while copper is more resilient but not enough to offset the drag from BHP’s bulk commodity exposure. Relative to the 2015-2016 China slowdown with some support from 2022 real-asset rotation, the 12-month target of $24.50 suggests BHP may hold up better than many cyclicals operationally, but the valuation framework still points to substantial downside from current levels. |
 BTC Bitcoin | 8% | -8% | -0.6% | Bitcoin is the outlier where the stated base and scenario fair value both remain $104,250, equal to the current price, so valuation itself does not drive the move; instead, the expected path is macro-liquidity-driven, with scenario targets of $83,400 at 6 months, $95,910 at 12 months and $114,675 at 24 months. The transmission starts with a March-2020-style risk-off and deleveraging shock through ETF flows, futures basis and broad portfolio liquidation, then potentially reverses as geopolitical fragmentation strengthens the non-sovereign reserve narrative. Relative to tech equities, BTC lacks earnings or chip-supply exposure, so its drawdown and recovery are primarily a function of liquidity stress versus later safe-haven adoption. |

Assets to watch
Winners & Losers
Which asset types and sectors tend to benefit or suffer
Potentially more exposed
Semiconductors and AI infrastructure
These assets sit closest to the lost Taiwan manufacturing base and face the most immediate operational disruption.
High sensitivityMega-cap growth and cloud platforms
High valuations and dependence on chip availability make them vulnerable to both earnings downgrades and multiple compression.
High sensitivityChina-linked industrials and materials
Trade freezes and weaker Chinese demand pressure volumes, pricing, and sentiment across cyclical sectors.
Medium sensitivityPotentially more resilient
Defensive healthcare
Less cyclical demand and more stable earnings can help this area outperform on a relative basis during a deep growth scare.
Low sensitivityIntegrated energy
War risk and sanctions can lift energy prices, supporting cash flows even if broader equities struggle.
Low sensitivityBitcoin and alternative hedges
These assets may initially sell off in a liquidity shock but could recover if geopolitical fragmentation boosts the non-sovereign store-of-value narrative.

Pre-built scenario prompt
“China successfully invades and takes control of Taiwan, immediately halting all semiconductor exports to the United States and allied nations. TSMC's advanced fabs, which produce over 90% of the world's most cutting-edge chips, go offline for Western customers. The US and allies impose sweeping sanctions on China, freezing trade and financial flows. A global chip famine cripples AI infrastructure buildouts, smartphone and PC production, automotive manufacturing, and defence systems. Tech giants face catastrophic supply chain disruption as years of inventory run dry within months. US domestic chip production via CHIPS Act facilities is insufficient to fill the gap. Markets reprice the entire semiconductor value chain, and a broader decoupling of the US and Chinese economies accelerates. Safe haven assets surge while growth and tech stocks face their worst drawdown since the dot-com bust.”
FAQ
Frequently asked questions
Common questions about portfolio scenario analysis and what this stress test reveals.
The shock is both fundamental and valuation-driven. Leading-edge chip supply is central to AI servers, smartphones, PCs, and cloud buildouts, so a loss of Taiwan capacity hits revenue directly while also forcing investors to reassess lofty growth assumptions.
No. Companies with direct semiconductor dependence, high valuations, or heavy China supply-chain exposure are typically hit hardest, while defensives such as healthcare and some energy names may hold up better on a relative basis.
Geopolitical conflict and sanctions can create a risk premium in oil and LNG markets. That can support energy earnings even as global growth slows, especially for large integrated producers with strong balance sheets.
Not quickly enough in this scenario. New CHIPS Act capacity would likely be insufficient in the near term to replace TSMC's advanced-node output, especially for the most sophisticated AI and high-performance computing workloads.
In the first phase, liquidity stress often dominates and risk assets can sell off together. Over time, however, a fractured global financial system could strengthen the appeal of non-sovereign assets, which is why the path may improve after the initial shock.
