Best Stocks to Buy in 2026: 15 High-Quality Stocks for Growth and Long-Term Investing
What are the best stocks to buy in 2026? Our 2026 research shortlist focuses on companies with durable competitive advantages, strong financial quality, attractive long-term growth opportunities and the ability to compound cash flow over many years.
We do not believe a stock should be called a “best buy” simply because its business is growing quickly. A great investment depends on business quality, growth, valuation, balance-sheet strength, catalysts, risk and portfolio role.
Our 15 Best Stocks to Buy in 2026
The list deliberately spans technology, semiconductors, healthcare, payments, infrastructure and diversified businesses. This is important because owning several companies with the same economic exposure is not the same as diversification. Investor.gov notes that diversification should occur both across asset classes and within them, including across industries and companies. Investor.gov.
Why we like it: NVIDIA remains one of the clearest beneficiaries of the accelerated-computing and generative-AI buildout. Its moat extends beyond GPUs into networking, software, CUDA and the broader AI computing ecosystem.
NVIDIA reported fiscal Q2 2027 revenue of $96.2 billion, up 106% year over year, while Data Center revenue reached $89.0 billion, up 117%. These figures demonstrate the extraordinary operating momentum behind the AI infrastructure cycle. NVIDIA investor relations.
Investor thesis: NVIDIA offers exceptional long-term exposure to AI compute, but the investment case becomes less attractive as expectations and valuation become increasingly demanding.
AIGPUData CentersLong-Term GrowthWhy we like it: Broadcom combines custom AI accelerators, networking technology and infrastructure software. That combination gives investors exposure to AI spending without relying exclusively on merchant GPUs.
Broadcom's Q3 fiscal 2026 revenue reached $29.6 billion, up 86% year over year. Free cash flow was $13.7 billion, equal to 46% of revenue, while management guided to approximately $34.8 billion of Q4 revenue. Broadcom investor relations.
Investor thesis: Broadcom is one of our favorite “picks and shovels” businesses for AI infrastructure because it participates in multiple layers of the data-center stack.
AINetworkingASICsFree Cash FlowWhy we like it: Microsoft has one of the strongest combinations of recurring revenue, enterprise distribution, cloud infrastructure, software ecosystems and AI optionality in the public markets.
For fiscal Q4 2026, Microsoft reported revenue of $90.0 billion, up 18%, and operating income of $40.6 billion, also up 18%. Net income increased 31% on a GAAP basis. Microsoft investor relations.
Investor thesis: Microsoft may be less explosive than smaller AI beneficiaries, but its breadth and recurring revenue make it one of the strongest long-duration compounders.
CloudAIEnterpriseRecurring RevenueWhy we like it: TSMC is the manufacturing backbone behind many advanced processors designed by leading technology companies. Its strategic importance rises as leading-edge semiconductor manufacturing becomes increasingly difficult and capital intensive.
TSMC reported Q2 2026 revenue of $40.2 billion and guided Q3 revenue to approximately $44.6 billion–$45.8 billion. TSMC quarterly results.
Investor thesis: TSMC offers indirect exposure to many AI winners while retaining a critical position in advanced semiconductor manufacturing.
FoundryAIAdvanced NodesTaiwanWhy we like it: Alphabet combines a dominant global search franchise with YouTube, Google Cloud, advertising technology and a rapidly evolving AI platform.
Investor thesis: Alphabet provides a different AI exposure from semiconductor companies. Its opportunity lies in using AI to improve search, advertising, cloud services and new products while monetizing a massive installed user base.
SearchCloudAIYouTubeWhy we like it: ASML occupies a uniquely strategic position in advanced semiconductor manufacturing because of its lithography technology and extremely difficult-to-replicate equipment ecosystem.
ASML reported Q2 2026 net sales of €9.3 billion and net income of €2.9 billion. The company raised its 2026 sales outlook to approximately €43 billion–€45 billion. ASML investor relations.
Investor thesis: ASML is a classic semiconductor “picks-and-shovels” investment. Its strategic importance can remain high even when individual chip designers change winners.
LithographyEUVSemiconductorsMoatWhy we like it: AMD gives investors exposure to CPUs, GPUs, data-center accelerators and adaptive computing, with significant potential to take additional share in AI and data-center markets.
Investor thesis: AMD has greater upside optionality than some mature technology companies, but its investment case is also more dependent on execution and competitive share gains.
CPUGPUAIData CenterWhy we like it: Eli Lilly combines a powerful pharmaceutical pipeline with exceptional momentum in diabetes and obesity medicines, particularly Mounjaro and Zepbound.
In Q2 2026, Lilly reported revenue of $23.0 billion, up 48%, and raised 2026 full-year revenue guidance to $85 billion–$87 billion. The company also highlighted continued development of retatrutide, including plans for a U.S. regulatory submission in 2027. Eli Lilly investor relations.
Investor thesis: Lilly provides an important healthcare growth component that reduces dependence on the semiconductor and AI cycle.
HealthcareObesityGLP-1PipelineWhy we like it: Applied Materials sells critical equipment used to manufacture advanced chips and displays. Its opportunity benefits from increasing process complexity, advanced packaging and semiconductor capacity investment.
Applied Materials reported record fiscal Q3 2026 revenue of $9.12 billion, up 25% year over year, with record non-GAAP EPS of $3.50. Applied Materials investor relations.
Investor thesis: AMAT is a way to participate in semiconductor manufacturing growth without making a single bet on which chip designer wins.
Semiconductor EquipmentAIAdvanced PackagingWhy we like it: KLA provides inspection, metrology and process-control technologies that become increasingly valuable as chip manufacturing grows more complex.
KLA generated fiscal 2026 free cash flow of approximately $3.77 billion. The company also completed a 10-for-1 stock split in June 2026. KLA investor relations.
Investor thesis: KLA is one of the more differentiated semiconductor-equipment businesses and can benefit from increasing manufacturing complexity.
MetrologyInspectionSemiconductorsWhy we like it: AI clusters require enormous networking capacity. Arista has built a strong position in high-speed cloud and data-center networking and is expanding its role as AI systems scale.
Arista reported Q2 2026 revenue of $3.036 billion, up 37.7% year over year, while non-GAAP EPS increased 40%. The company also introduced 1.6 Tbps AI fabric platforms. Arista investor relations.
Investor thesis: Arista is a useful diversification within the AI infrastructure theme because networking becomes increasingly important as compute clusters grow.
NetworkingAI Data CentersCloudWhy we like it: Visa operates one of the world's most important electronic payments networks and benefits from the long-term migration from cash and checks toward digital payments.
Visa describes its network as serving consumers, merchants, financial institutions and governments across more than 200 countries and territories. Visa investor relations.
Investor thesis: Visa adds a non-AI growth engine to the portfolio and has the potential to compound through global electronic-payment adoption.
PaymentsNetwork EffectsGlobalWhy we like it: Berkshire provides exposure to a diversified collection of operating businesses, insurance, investments and substantial financial resources.
Investor thesis: Berkshire can serve as a stabilizing component within an otherwise growth-heavy stock portfolio. Its appeal is less about explosive growth and more about financial resilience and diversified cash-generating businesses.
DiversifiedInsuranceCapital AllocationWhy we like it: Eaton sits at the intersection of electrification, grid modernization, industrial automation and rising data-center power demand.
Investor thesis: Eaton gives the portfolio exposure to an important second-order AI theme: the physical infrastructure required to power data centers and modernize electricity systems.
GridElectrificationData CentersInfrastructureWhy we like it: AI servers require enormous amounts of advanced memory. Micron is therefore positioned at an important layer of the AI infrastructure stack, although memory economics remain more cyclical than many software or platform businesses.
Micron reported record fiscal Q4 2026 revenue of $54.23 billion and fiscal 2026 revenue of $133.19 billion. The company attributed the outlook for fiscal 2027 to AI-driven demand and execution. Micron investor relations.
Investor thesis: Micron offers potentially powerful AI-driven earnings growth, but investors should treat it as a more cyclical semiconductor investment than Microsoft, Visa or Berkshire Hathaway.
MemoryHBMAISemiconductorsOur 2026 Stock Selection Framework
We do not rank stocks simply by recent share-price performance. Our framework asks whether a company can create value over a multi-year investment horizon.
1. Competitive Moat
Does the company possess technology, network effects, switching costs, scale, intellectual property, distribution or another durable advantage?
2. Revenue & Earnings Growth
Are growth opportunities supported by real customer demand rather than merely optimistic narratives?
3. Free Cash Flow
Strong accounting earnings are useful, but sustainable free cash flow provides greater flexibility for investment, acquisitions, dividends and buybacks.
4. Financial Strength
We prefer businesses capable of surviving economic slowdowns without relying excessively on refinancing or external capital.
5. Valuation
Even an outstanding company can be a poor investment when the market price already assumes an unrealistic future.
6. Catalysts
Potential catalysts include new products, market-share gains, AI adoption, capacity expansion, regulatory approvals, pricing power or operating leverage.
Great Company vs. Great Stock
This distinction is central to our methodology.
Therefore, a company can remain on our “best stocks” research list while its shares move into an expensive valuation zone. That does not necessarily mean the business is bad; it means the margin of safety has changed.
Best Stocks by Investment Theme

How Much of Your Portfolio Should Go Into Individual Stocks?
A common mistake is turning a list of attractive stocks into an undiversified portfolio.
Investor.gov explains that diversification should occur across different investments and industries, and notes that a portfolio containing only four or five individual stocks is not truly diversified. Read the Investor.gov diversification guide.
For many long-term investors, a broad-market ETF can form the core of a portfolio, while individual stocks are used selectively for additional exposure to businesses or themes in which the investor has high conviction.
Stocks vs. ETFs: Which Is Better?
There is no universal winner.
Individual stocks offer the possibility of outperforming the market, but they also introduce company-specific risk.
Broad-market ETFs provide instant diversification and reduce the damage caused by an individual company performing poorly.
A sensible long-term structure can therefore combine a diversified ETF core with a smaller allocation to carefully researched individual companies.
What Could Go Wrong With These Stocks?
The most important risk is expectations. Many of the companies on this list are priced around strong future growth. If growth slows, margins contract or capital spending disappoints, the share price can decline even while the business remains profitable.
For AI-related stocks specifically, investors should monitor:
AI infrastructure spending → customer concentration → semiconductor supply → competition → export restrictions → electricity and data-center constraints → valuation → eventual returns on AI investment.
The 2026 market has demonstrated both the power and the risk of this theme. Recent market commentary has highlighted strong AI-related earnings and spending while also pointing to elevated Treasury yields and the need for investors to remain selective. Recent market coverage.
Stocks We Would Not Automatically Buy at Any Price
We deliberately avoid treating this list as a perpetual buy signal.
NVDA, AVGO, AMD, ANET, ASML, KLAC, AMAT and MU can all remain outstanding businesses while becoming less attractive investments at very high valuations.
The correct question is not:
“Is this a great company?”
It is:
“Is the current price reasonable relative to the company's future cash flows, competitive position and risks?”
How to Build a Long-Term 15-Stock Portfolio
An investor who wants to use this list as a research universe could think in terms of economic exposure rather than simply allocating equal amounts to every ticker.
Illustrative Structure
Core compounders: MSFT, GOOGL, V, BRK.B
AI / semiconductor growth: NVDA, AVGO, AMD, TSM
Semiconductor infrastructure: ASML, AMAT, KLAC, MU
Healthcare: LLY
Networking / infrastructure: ANET, ETN
This is a framework for thinking about diversification, not a recommended percentage allocation.
When Is the Best Time to Buy?
Trying to identify the exact bottom or top of a stock is extremely difficult.
For long-term investors, a more practical approach is to establish a valuation range, determine the investment thesis and then buy gradually when the risk/reward becomes attractive.
For exceptionally high-quality companies, investors may choose to build positions over time rather than waiting indefinitely for a perfect entry point.
Our 2026 Investment Principles
1. Buy businesses, not stories.
A compelling narrative is not enough without revenue, earnings and cash flow.
2. Respect valuation.
The best company can still produce poor investment returns when purchased at an excessive price.
3. Diversify economic exposures.
Owning NVDA, AMD, AVGO and MU is not the same as owning four unrelated businesses.
4. Think in years, not weeks.
Our focus is on durable business economics rather than short-term price predictions.
5. Re-underwrite the thesis.
A stock should be reviewed whenever earnings, competitive dynamics, regulation or valuation materially changes.
Frequently Asked Questions
What are the best stocks to buy in 2026?
Our 2026 research list includes NVIDIA, Broadcom, Microsoft, TSMC, Alphabet, ASML, AMD, Eli Lilly, Applied Materials, KLA, Arista Networks, Visa, Berkshire Hathaway, Eaton and Micron. The appropriate stock depends on valuation, risk tolerance, time horizon and portfolio diversification.
What is the best AI stock to buy in 2026?
NVIDIA is one of the clearest direct AI-compute leaders, while Broadcom, Microsoft, Alphabet, AMD and Arista provide different forms of AI exposure. The best choice depends heavily on valuation and the specific part of the AI value chain an investor wants to own.
Are semiconductor stocks still worth buying in 2026?
Semiconductors remain strategically important because AI, cloud computing, networking and advanced computing require increasingly sophisticated chips. However, semiconductor stocks are cyclical and can experience significant valuation and earnings volatility.
Should beginners buy individual stocks?
Beginners should understand diversification and risk before building a concentrated stock portfolio. Broad-market ETFs can provide diversification, while individual stocks can be added when the investor understands the business and accepts company-specific risk.
How many individual stocks should I own?
There is no universal number, but diversification becomes substantially better as investors spread exposure across multiple companies and industries. Investor.gov notes that four or five individual stocks are not enough for a truly diversified stock allocation. Investor.gov.
Is a good company always a good investment?
No. Investment returns depend on both business performance and the price paid. A wonderful business purchased at an excessive valuation can produce disappointing returns.
Bottom Line
The best stocks to buy in 2026 are not necessarily the stocks with the most exciting headlines or the strongest performance over the past few months.
Our preferred candidates combine durable competitive advantages, sustainable growth, strong cash generation, financial resilience, attractive long-term markets and valuations that can support an acceptable expected return.
That is why this list intentionally goes beyond AI. NVIDIA and Broadcom give investors powerful AI exposure, but Microsoft, Alphabet, Visa, Berkshire Hathaway, Eli Lilly and Eaton add businesses with different economic drivers.
For long-term investors, the objective is not to predict which stock will rise the most next month. It is to build exposure to high-quality businesses capable of compounding shareholder value for many years while maintaining enough diversification and valuation discipline to survive the inevitable periods when the market is wrong.
