3 High-Conviction Growth Stocks to Buy and Hold for the Next Decade

In the ever-evolving landscape of global markets, identifying companies with durable competitive moats and alignment with secular tailwinds is critical for long-term investors. Three stocks-BYD, SoFi Technologies, and Alphabet-stand out as compelling candidates for a decade-long holding. Each leverages technological innovation, strategic expansion, and structural advantages to dominate their respective industries. Below, we dissect their strengths and growth catalysts.

1. BYD: The Unstoppable Force in Electric Vehicles and Battery Innovation

BYD's ascent as the world's leading new energy vehicle (NEV) manufacturer is no accident. In the first nine months of 2025, the company captured 19.3% of global plug-in vehicle sales, outpacing rivals like Tesla. This dominance is underpinned by its vertically integrated business model, which includes in-house battery production, software development, and a rapidly expanding global footprint.

At the heart of BYD's success is its Blade Battery technology, a lithium iron phosphate (LFP) innovation that combines safety, cost efficiency, and scalability. LFP batteries are 30% cheaper per kWh than the nickel-based alternatives used in the U.S. and Europe, giving Chinese automakers like BYD a significant edge in price-sensitive markets. By 2025, BYD's subsidiary FinDreams Battery had become the second-largest EV battery manufacturer globally, with production capacity expanding into Thailand, Hungary, Brazil, and Turkey.

The company's R&D investments-up 53% year-over-year-are fueling further differentiation. BYD is already testing solid-state batteries for a 2027 launch, which promise higher energy density and safety. Meanwhile, its modular e-Platform 3.0 enables rapid model introductions, as evidenced by the 21 new EVs launched in early 2025. With over 36% of revenue now coming from overseas markets, BYD is poised to capitalize on the global EV transition, even as margins face short-term pressures.

2. SoFi Technologies: The Digital Banking Disruptor

SoFi's transformation from a student loan refinance startup to a $962 million revenue-generating fintech giant in Q3 2025 underscores its disruptive potential. The company's 12.6 million members and 18.6 million products reflect a one-stop-shop model that integrates banking, lending, investing, and now crypto trading-a first among nationally chartered banks.

SoFi's competitive advantages are structural. Its national bank charter, secured in 2022, allows it to fund loans with low-cost deposits, reducing reliance on external capital. This model, combined with a 40% cross-sell rate (40% of new products in Q3 2025 came from existing members), creates a self-reinforcing "Financial Services Productivity Loop" that boosts customer lifetime value. The company's foray into blockchain-based international remittances and AI-powered tools like Cash Coach further differentiates it from peers. SoFi's 38% year-over-year revenue growth and 29% EBITDA margin in Q3 2025 highlight its operational discipline. While exact market share figures remain elusive, SoFi's ability to innovate in high-growth areas-such as crypto and AI-driven personal finance-positions it to capture a growing share of the $60.33 billion U.S. digital banking market by 2035.

3. Alphabet: The AI and Cloud Behemoth

Alphabet's dominance in AI and cloud computing is a masterclass in leveraging first-mover advantages. Google Cloud revenue grew 34% year-on-year in 2025, with market share expanding from 10% in Q1 2023 to 12% in Q1 2025. This growth is driven by Alphabet's vertically integrated AI stack, including custom Tensor Processing Units (TPUs) and its Gemini large language model (LLM), which ranks among the industry's best. Unlike rivals that rely on third-party AI models, Alphabet's in-house capabilities reduce costs and improve efficiency. Its seventh-generation TPUs are now available to enterprise clients via Google Cloud, creating a flywheel effect as AI adoption accelerates. The proposed $32 billion acquisition of Wiz, a cybersecurity firm, signals Alphabet's intent to strengthen its cloud offerings.

Secular tailwinds are equally compelling. The global AI market is projected to grow at a 15.9% CAGR through 2029, driven by demand for generative AI tools and enterprise automation. Alphabet's dominance in search, advertising, and cloud positions it to monetize these trends for decades. Analysts have upgraded price targets, citing Alphabet's ability to combine AI innovation with its existing infrastructure-a durable moat in an increasingly digital world.

Conclusion: Moats, Tailwinds, and Long-Term Value

BYD, SoFi, and Alphabet each exemplify the intersection of technological leadership, strategic execution, and structural advantages. BYD's battery expertise and global expansion, SoFi's integrated financial ecosystem, and Alphabet's AI/cloud dominance are not fleeting trends but foundational shifts with multi-decade horizons. For investors seeking compounding growth, these stocks offer a rare combination of defensibility and upside.
