Daily Market Brief - Dec 31, 2025
Editor's Notes:
- Going into 2026, sentiment remains mixed and dominated by the debate around AI, with defense, metals & mining, the AI supply chain, JP MBOs, and China consumption on top of investors' minds. While valuations are rich, there is healthy skepticism, topical concentration, and plenty of debate—promising likely high volatility and a good hunting ground for alpha in 2026.
- As everyone closes out 2025 with hopefully fantastic returns, we wish you a happy and prosperous New Year!
Key takeaways include the persistent debate over AI's valuation (inflection point versus bubble), Japan's 'golden era' of undervaluation and activism, and mixed signals from Hong Kong. This analysis delves into critical market themes, notable stock movements, and emerging investment ideas to help professional investors navigate current trends.
Overall Themes, Market Sentiment & Debates
Global Market Overview: A Complex Tapestry
Market sentiment remains a paradox. The debate around the 2026 economic outlook is polarizing, oscillating between predictions of a "melt-up" fueled by liquidity and potential policy shifts, and fears of a "turbulent market" or even a "new lost decade" should the current AI boom prove to be a bubble. The persistent Shiller PE near dot-com levels underscores this valuation tension.
US Market: AI at an Inflection Point (or Bubble)?
The US market continues to be dominated by the AI narrative, driving both excitement and considerable debate. The core question is whether this is an "inflection bubble" leading to societal progress despite capital destruction, or a "mean-reverting bubble" with net-negative economic outcomes. Concerns around "circular deals" – large commitments potentially distorting return on invested capital – echo historical parallels to the dot-com and telecom bubbles, reminding investors that even transformative technology can lead to poor returns if valuations become excessive.
The autonomous vehicle race encapsulates this tension. Waymo, a subsidiary of Alphabet, adopts a "slow methodical," infrastructure-heavy approach. This contrasts with Tesla's "quick to market" owner-operator model. The long-term winner may well be the one with owned infrastructure and control, making Waymo's strategy potentially more sustainable against Tesla's model, which may have an "expiry date" without similar vertical integration.
Japanese Market: Undervaluation Meets Activism
The Nikkei 225 continues to hover near record highs after a robust 26% annual gain, largely powered by technology. However, a recent pause in tech rallies suggests profit-taking. Beyond tech, a "golden era" is unfolding for private equity and activist investors targeting undervalued, illiquid assets. Governance reform momentum is viewed as irreversible, attracting significant capital and driving strategic shifts like Management Buy Outs (MBOs), Private Equity (P/E) buyouts, and asset divestments. This is particularly evident in firms like Yomeishu Seizo, which saw a 24% limit-up on KKR's negotiation rights for a potential delisting, highlighting the perceived undervaluation of its real estate assets. Similarly, Yutaka Giten is facing activist pressure for MBOs and P/E buyouts. This trend extends to niche sectors like Japanese Home Care/Hospice, where stringent regulatory enforcement creates potential for undervalued opportunities post-downturn recovery.
Hong Kong Market: Mixed Signals Amid Sectoral Pullback
Hong Kong witnessed a mixed performance. While some technology names showed resilience, with Baidu (HK:9888) being a strong performer driven by tech momentum, the broader "new consumer concept" stocks experienced a significant pullback. This sector-wide retreat, exemplified by declines in Laopu Gold (HK:6181) and Pop Mart (HK:9992), indicates broader pressure and volatility. This is potentially exacerbated by holiday trading patterns and underlying questions about consumer demand sustainability. Despite this, the semiconductor sector, with SMIC (HK:0981) gaining on a subsidiary acquisition, demonstrated underlying strength.

Interesting Comments, Facts & Ideas
AI's Shifting Sands: Beyond the Hype
- NVIDIA (NVDA): Michael Burry’s thesis raises a critical point: NVIDIA’s AI hardware depreciation might be understated (2-3 years useful life versus 5-6 years accounting), potentially inflating earnings. This echoes Cisco in the dot-com era, suggesting a need to scrutinize underlying asset longevity. SoftBank's $5.8 billion NVDA stake liquidation to fund a $40 billion OpenAI investment further signals a strategic shift from NVDA.
- Advanced Micro Devices (AMD): Positioned as a strong contender, AMD's MI300X offers memory advantages over NVIDIA’s H200 at a fraction of the cost. Its growing traction in data centers, AI segments, and a maturing ROCm software ecosystem under Lisa Su's leadership are key bullish drivers.
- EoS Energy (EOSE): This "Sleeping Giant" manufactures US-made Zinc-based battery storage systems, ideal for AI/Hyperscale Battery Energy Storage Systems (BESS) and long-duration backup. Anticipating strong Q4 2025 revenue, EOSE is set to benefit from increased China lithium tariffs in 2026.
- Symbotic (SYM): Bullish sentiment argues its "pure-play robotics company" valuation overlooks its 35% stake in Green Box, an AI warehouse-as-a-service joint venture (JV) with SoftBank. This suggests a massive Total Addressable Market (TAM) and potential for significant re-rating.
- Warrior Met Coal (HCC): The "AI Trade Nobody Wants to Make" highlights the overlooked necessity of metallurgical coal for steel production, crucial for new AI data centers. Operating in a supply-constrained industry with ultra-low costs and superior logistics, HCC presents a unique, albeit ethically contentious, opportunity.
- SRXH: Touted as an "asymmetric setup" following a radical pivot from healthcare to AI-driven Fintech (Treasury management) with OpenAI Large Language Model (LLM) integration. A massive share cancellation and upcoming catalysts (EMJX acquisition, rebrand, new CEO) are expected to drive a significant re-rating.
- Yelp (YELP): Despite solid fundamentals (EV/EBITDA 6.15, Return on Invested Capital (ROIC) ~20%, buybacks), Yelp is grappling with AI-driven competitive threats, particularly from Google. The debate is whether the market is overreacting or if Yelp faces an imminent structural decline in its core business model.
- Conagra Brands (CAG): "Project Catalyst," a multi-year initiative leveraging AI and new technologies to enhance operational efficiency across its operations, could unlock significant value for this consumer staples giant.
Value, Event-Driven & Niche Opportunities
- W.R. Berkley Corp. (WRB): Two large open-market purchases by Mitsui Sumitomo (a ~10% holder) totaling over $100 million, even at higher prices, signal strong insider confidence from a reputable investor.
- Compass, Inc. (COMP): A notable single-block call options sweep ($1.47 million premium for Jan 2026 $12 strike) indicates significant bullish institutional interest, suggesting a potential positive catalyst is on the horizon.
- Coeur Mining (CDE): Considered "extremely undervalued" with a potential merger with NGD, creating 7 operations across North America, strong revenue growth, consistent profits, and an ongoing share buyback program.
- Pool Corporation (POOL): A "high-quality, durable franchise" acting as a specialized logistics utility for swimming pools. Its recurring maintenance business ("Blue" business) benefits from network density, scale, and expertise, coupled with shareholder-friendly capital allocation.
- Kongsberg Gruppen (KBGGY): This Norwegian defense conglomerate is "uniquely positioned" at the intersection of the EU defense supercycle and maritime decarbonization. High growth, capital efficiency, strong moats (missiles, maritime tech), and a proposed split in April 2026 are key value unlock catalysts.
- Locksley Resources (LKY/LKYRF): A critical minerals (antimony, Rare Earth Elements - REE) explorer focusing on US assets, with active drilling programs and strong funding, tapping into strategic resource themes.
- Factorial Energy: Positive sentiment followed its IPO after a solid-state EV battery test achieved over 745 miles, supported by partnerships with Mercedes-Benz, Stellantis, and Hyundai, positioning it in a critical EV technology.
- Optrex System (OPXS): An "under the radar" defense tech stock with 95% market share in optical systems (periscopes for tanks), 20% revenue growth, a Price-to-Earnings (PE) ratio of 19, and potential as an acquisition target.
Biotech & Pharma Catalysts
- Gilead Sciences (GILD): Advanced next-generation antiviral therapies for Herpes Simplex Virus (HSV) recurrence, and licensed Assembly Bio's HSV helicase-primase inhibitor programs (ABI-1179 and ABI-5366) with positive Phase 1b data, targeting once-weekly oral dosing.
- Moderna (MRNA): Expanded clinical research into mRNA-based therapeutic vaccines, with a focus on the long-term management of Herpes Simplex Virus (HSV).

Auto Sector & Beyond
- Lucid Group (LCID): Identified as having the highest short interest ratio (54.51%) among eligible stocks. This suggests significant bearish sentiment but also implies a potential for a short squeeze if positive catalysts emerge.
Broader Strategies
- Dogs of the Dow (2026 Picks): The mechanical strategy, selecting the 10 highest dividend-yielding DJIA stocks (e.g., Verizon, Chevron, Merck), performed well in 2025 and is expected to benefit from potential lower interest rates.
- Gold / Silver (SLV, PPLT): Seen as reliable commodities, a hedge against market volatility, and possessing positive underlying fundamentals for 2026 despite recent profit-taking.
- Morality of Investing: The "Metallurgical Coal" pitch ignited a "pro-progress/pro-planet debate," highlighting the ethical dilemmas of supporting industries crucial for economic development (like steel for AI infrastructure) that also carry environmental costs.
