US Stock Market Preview 0119

Major events and trends in global markets and the tech industry this week:

1. Macroeconomic and policy risks

Inflation indicators incoming: The Fed's most-watched November core PCE inflation data will be released this week. If the data rebounds, it could impact market expectations for rate cuts.

Trump tariff controversy: Trump announced a 10% tariff increase on eight European countries (reasons include the Greenland acquisition dispute). Many European countries strongly oppose this and have threatened countermeasures against major U.S. tech companies, potentially escalating geopolitical and trade risks.

Political figure movements: Trump will attend the Davos Forum, and the U.S. Supreme Court may rule on related tax cases.

2. Major moves by AI giants

Google: Released the open-source multimodal medical model Med-Gemini (MJ1.5), hailed as the world's first "AI all-round doctor," capable of understanding various medical images and documents like CT, MRI, and X-rays, with relatively low computing power requirements.

Musk vs. OpenAI/Microsoft: Musk sued OpenAI and Microsoft for fraud and violating their nonprofit mission, seeking damages of up to $134 billion. The case is expected to go to trial in April.

Computing power upgrade: Musk's first global GW-level computing cluster, Colossus 2, is now operational, with an upgrade to 1.5GW expected in April, consuming staggering energy.

3. Latest Tesla updates

FSD subscription model: Musk announced that starting February 14, FSD will only be available via subscription, with no outright purchase option. This has sparked polarized reactions among owners, with analysts believing it could expand the user base but may affect older owners' willingness to upgrade.

China localization: The Chinese version of Model Y will integrate ByteDance's Volcano Engine (Doubao) and DeepSeek to enhance in-car voice dialogue and reasoning capabilities, addressing localization content gaps.

4. Market investment strategies

U.S. electricity price surge: Electricity prices have risen by about 38% since 2020, with high-energy-consuming AI data centers becoming a political focus. Goldman Sachs recommends investors hedge policy risks by going long on non-AI-benefiting companies.

2026 U.S. stocks: Wall Street predicts U.S. stocks will show "rising prices but increasing volatility." It advises against blindly chasing the "Magnificent Seven" tech giants and instead shifting to structured trading and hedging strategies.

5. Other key data

China will release full-year and Q4 2025 GDP data.

The Bank of Japan will announce its interest rate decision.

The U.S. earnings season continues, with Netflix, Intel, Johnson & Johnson, and others reporting.

This week, macroeconomic policies and corporate fundamentals intertwine, significantly increasing market volatility risks—stay vigilant.
