2. DeepSeek – The Disruptor That Shook the AI World
The emergence of DeepSeek in January 2025 marked a turning point in the AI investment landscape. The Chinese AI company’s low-cost model challenged the fundamental assumptions driving AI stock valuations.
- The $1 Trillion Wipeout: DeepSeek’s announcement triggered a massive sell-off in AI stocks, wiping out nearly $1 trillion from the Nasdaq in a single day.
- Challenge to the AI Narrative: DeepSeek’s model was reportedly trained for under $6 million, a fraction of the billions spent by US tech giants. This raised fundamental questions about the sustainability of high AI chip prices and the massive capex commitments of Big Tech.
- Nvidia’s Sharp Decline: Nvidia shares fell approximately 17% in a single day, reflecting the market’s immediate reaction to the potential threat of lower-cost AI alternatives.
- China’s AI Ambitions: DeepSeek’s emergence highlighted China’s growing capabilities in the AI space, adding a geopolitical dimension to the AI investment thesis.
- Recovery and Reassessment: While the market quickly recovered, DeepSeek’s impact was lasting. Investors began to reassess the moats of AI companies and the sustainability of current valuation levels.

3. Nvidia – From 2025 Dominance to 2026 Questions
Nvidia was the undisputed king of AI stocks in 2025, but 2026 brings new challenges as competition intensifies and valuations come under scrutiny.
| Metric | 2025 | 2026 Outlook |
|---|---|---|
| Annual Return | +28.5% | More volatile |
| Market Cap | ~$3.5 Trillion | Overtaken by Apple |
| AI Chip Market Share | ~80% | Under pressure |
| Data Centre Revenue | Strong Growth | Continued Growth |
| Valuation (P/E) | ~50x | Stretched |
- 2025 Performance: Nvidia ended 2025 with a 28.5% annual return, despite the January sell-off triggered by DeepSeek. The company’s data centre business continued to grow at a rapid pace, driven by the insatiable demand for AI compute.
- January 2026 — Apple Overtakes Nvidia: In January 2026, Apple overtook Nvidia in market capitalisation, reflecting shifting investor sentiment and concerns about Nvidia’s long-term competitive position.
- Competition Intensifies: AMD, Intel, and a host of AI chip startups are challenging Nvidia’s dominance. DeepSeek’s low-cost model also raised questions about whether enterprises will continue to pay premium prices for Nvidia chips.
- Valuation Scrutiny: With a price-to-earnings ratio of around 50x, Nvidia’s valuation remains stretched. Investors are increasingly asking whether the company can sustain its growth trajectory in a more competitive environment.
- Long-Term Thesis: Despite near-term challenges, Nvidia remains a key beneficiary of the AI revolution. The company’s CUDA ecosystem, software stack, and continued innovation provide a strong competitive moat.

4. Nasdaq – 2025 Rally vs 2026 Headwinds
The Nasdaq Composite’s 28.6% rally in 2025 was one of the strongest performances in years, but 2026 presents a more challenging environment.
- 2025 — The AI Rally: The Nasdaq’s 2025 rally was driven almost entirely by AI-related stocks. The “Magnificent Seven” — Nvidia, Microsoft, Apple, Alphabet, Amazon, Meta, and Tesla — accounted for a significant portion of the index’s gains.
- Valuations Stretched: By the end of 2025, valuations in the tech sector had reached elevated levels, with many AI stocks trading at multiples that left little room for disappointment.
- DeepSeek’s Lingering Impact: The DeepSeek episode revealed the vulnerability of the AI narrative to disruptive innovations. The market now has to price in the possibility of similar disruptions in the future.
- Fed Policy Uncertainty: While the Fed cut rates in 2025, the pace of cuts in 2026 remains uncertain. Sticky inflation and a resilient economy could lead to higher-for-longer interest rates, which would weigh on tech valuations.
- Corporate AI Capex: Despite the headwinds, Big Tech companies continue to invest heavily in AI infrastructure. Microsoft, Google, Amazon, and Meta are expected to spend over $200 billion on AI-related capital expenditure in 2026, providing a floor for AI-related stocks.

- Nasdaq: The 28.6% rally in 2025 is unlikely to repeat in 2026, given stretched valuations and more uncertain economic conditions.
- Nvidia: While Nvidia remains a key AI player, its dominance is being challenged by competitors and the emergence of low-cost alternatives like DeepSeek.
- AI Capex: Big Tech’s commitment to AI infrastructure remains strong, providing a tailwind for AI-related stocks.
- Valuations: With valuations at elevated levels, the risk-reward trade-off for AI stocks has become less favourable compared to 2025.
- Investment Strategy: A more selective, diversified approach is required in 2026. Focus on quality AI plays with strong moats and reasonable valuations.

6. Investment Strategies for AI Stocks in 2026
Navigating the AI stock market in 2026 requires a thoughtful, diversified approach.
| Strategy | 2025 Focus | 2026 Focus |
|---|---|---|
| Semiconductor | Nvidia dominant | Nvidia + AMD + Broadcom |
| Cloud & Infrastructure | AWS, Azure, GCP | Cloud + data centres + power |
| AI Software | Microsoft, Salesforce | AI applications, enterprise AI |
| AI Enablers | Semiconductors | Power grids, cooling, equipment |
| China Exposure | Avoided | Selective consideration |
- Diversify Across the AI Value Chain: Don’t concentrate all your AI exposure in a single stock. Spread investments across semiconductors (Nvidia, AMD, Broadcom), cloud providers (AWS, Azure, GCP), AI software (Microsoft, Salesforce, ServiceNow), and AI infrastructure enablers.
- Focus on Quality: With valuations stretched, focus on companies with strong moats, sustainable competitive advantages, and the ability to generate free cash flow.
- Consider AI Infrastructure Plays: The buildout of AI infrastructure requires more than just chips. Power grids, data centres, cooling systems, and networking equipment are all beneficiaries.
- Don’t Ignore China: While geopolitical risks remain, China’s AI capabilities, as demonstrated by DeepSeek, cannot be ignored. Consider selective exposure to Chinese AI plays.
- Maintain a Long-Term Horizon: AI is a multi-year trend. Short-term volatility is inevitable, but the long-term growth thesis remains intact.

7. Common Mistakes to Avoid in AI Stock Investing
Chasing momentum blindly
AI stocks saw massive gains in 2025, but momentum can reverse quickly. DeepSeek’s emergence wiped out $1T in a single day.
Ignoring valuations
Many AI stocks trade at 50x+ P/E ratios. A small earnings miss can lead to significant downside.
Overconcentration
Nvidia was the star of 2025, but putting all your money in one stock is risky. Diversify across the AI value chain.
Underestimating competition
DeepSeek proved that competition can come from unexpected places. AMD, Intel, and Chinese players are challenging Nvidia’s dominance.
