Johnson & Johnson

NYSE:JNJ

Johnson & Johnson is a healthcare company that sells prescription medicines and medical devices. Its drug business focuses on treatments in areas such as immunology, oncology, neuroscience, and infectious disease, while its medical technology business sells products used in surgery, orthopedics, vision care, and other hospital and clinic settings. It no longer includes the consumer health brands that were separated into Kenvue. Its main customers are hospitals, doctors, surgical centers, pharmacies, insurers, and government health systems, along with patients who use its prescription treatments. Johnson & Johnson makes money mainly by selling branded products through the healthcare supply chain, often under long-term reimbursement and purchasing arrangements. Because many of its products are used in regulated medical settings, the company relies on trust, clinical evidence, and relationships with doctors and hospitals rather than quick consumer sales. What makes Johnson & Johnson different is its mix of drug research and medical devices under one company. That gives it exposure to two large parts of healthcare: medicines that patients take over time and equipment that clinicians use in procedures and hospital care. The business tends to be durable because both product lines are tied to medical need, regulatory approval, and repeat use in everyday healthcare systems.

Berkshire Hathaway Inc

NYSE:BRK.A

Berkshire Hathaway is a large holding company that owns a mix of businesses and investments. Its core job is to collect cash from the companies it owns, then use that cash to buy more businesses, stocks, and other assets. It owns well-known insurance businesses such as GEICO and several reinsurance operations, along with rail transport, utilities, energy, manufacturing, retail, and service companies. The company makes money in two main ways. First, its operating businesses sell products and services directly to customers, such as car insurance, freight transport, electricity, building materials, and everyday consumer goods. Second, its insurance operations generate “float,” which is money collected from policyholders before claims are paid. Berkshire can invest that float and keep the returns, which gives it a long-running source of capital. What makes Berkshire different is that it is not built around one product or one industry. It acts more like a permanent owner of cash-generating businesses run with a lot of independence, while the parent company allocates capital across the whole group. That structure makes Berkshire both an insurer and an industrial owner, with a big investment portfolio attached, so its value depends on how well its operating companies and investment decisions work together.

Bank of America Corp

NYSE:BAC

Bank of America is one of the largest banks in the United States. It takes deposits, makes loans, and handles payments for households, small businesses, large companies, and governments. It also runs a major wealth management and investment banking business, helping clients manage cash, invest, trade securities, and raise capital. The bank makes money mainly by earning interest on loans and other credit products, plus fees for services such as card processing, brokerage, advisory work, and account maintenance. Its main customers include everyday consumers with checking and savings accounts, borrowers with mortgages or credit cards, small and midsize businesses that need lending and cash management, and large corporate and institutional clients that need market and financing services. What makes Bank of America’s business model different is its role as a full-service financial utility for a wide range of clients. A single customer may use it for deposits, borrowing, investing, payments, and business banking, which gives the bank many ways to earn revenue and keeps it deeply embedded in daily financial activity.

Mastercard Inc

NYSE:MA

Mastercard is a global payments network. It does not usually lend money to shoppers itself or make the physical card; instead, it connects banks, merchants, and consumers so card payments can move securely from one side to the other. When you tap, swipe, or buy online with a Mastercard-branded card, its network helps authorize and route the transaction. The company makes money mainly by charging fees tied to payment activity and by selling services around those payments, such as fraud prevention, data tools, and cross-border transaction processing. Its main customers are banks and other financial institutions that issue cards, along with merchants and payment processors that accept them. Consumers use the cards, but the banks and merchants are the direct business customers. Mastercard sits in the middle of the card payments system, which gives it a very specific role: it earns from the movement of money rather than from lending or holding large retail deposits. That makes its business tied to everyday consumer spending, e-commerce, travel, and business payments across many countries and currencies.

Salesforce Inc

NYSE:CRM

Salesforce makes cloud software that helps companies track customers, manage sales leads, handle service requests, and run marketing and commerce work. Its main products are the Salesforce platform and related business apps, which companies use to keep customer records in one place and coordinate work across sales, support, and marketing teams. Its customers are mostly businesses, from small firms to large enterprises, plus public-sector organizations. Salesforce usually sells subscriptions and support, so customers pay to use the software rather than buying it outright. The company also earns money from add-on products and services that expand what its software can do. What makes Salesforce different is that it sits at the center of a company’s customer data and workflow, rather than being just one back-office tool. That gives it a sticky role in the business stack: once a company builds its sales and service process around Salesforce, it often keeps using the platform and adds more products over time.

UnitedHealth Group Inc

NYSE:UNH

UnitedHealth Group is a healthcare company with two main businesses: health insurance and healthcare services. Through UnitedHealthcare, it sells insurance plans to employers, individuals, and government programs. Through Optum, it also runs businesses that help deliver care, manage prescription benefits, process claims, and support doctors and health systems with data and technology. Most of UnitedHealth Group’s money comes from insurance premiums and fees for healthcare services. Employers and members pay for coverage, health plans pay claims, and healthcare customers pay Optum for pharmacy benefit management, care delivery, analytics, and other services. This gives the company a mix of recurring revenue tied to both insurance enrollment and the day-to-day running of the healthcare system. What makes UnitedHealth Group different is that it sits on both sides of healthcare at once. It does not just insure patients; it also helps manage where care is delivered, how prescriptions are handled, and how medical information moves through the system. That makes it a major middleman in U.S. healthcare, connecting patients, doctors, hospitals, pharmacies, employers, and government payers.

Exxon Mobil Corp

NYSE:XOM

Exxon Mobil is one of the world’s largest oil and gas companies. It finds and produces crude oil and natural gas, then turns those raw materials into products people use every day, such as gasoline, diesel, jet fuel, lubricants, and petrochemicals used in plastics and industrial materials. Its main customers are other energy companies, fuel distributors, refiners, chemical makers, shipping and airline operators, and ultimately drivers, factories, and households that buy products made from oil and gas. Exxon Mobil makes money by selling the oil, gas, fuels, and chemicals it produces, along with specialized products like motor oils and industrial lubricants. What makes Exxon Mobil’s business model distinctive is that it sits across the whole energy chain, from drilling and production to refining and chemicals. That gives it more ways to earn money than a pure producer or a pure refiner, and it plays a central role in turning underground resources into the finished fuels and materials that modern economies still rely on.

Pfizer Inc

NYSE:PFE

Pfizer is a global drug company that discovers, develops, makes, and sells prescription medicines and vaccines. It sells treatments in areas such as vaccines, cancer, inflammation, rare diseases, internal medicine, and hospital care. Its customers are doctors, hospitals, pharmacies, governments, and health systems that buy and use its products for patients. Pfizer makes money mainly by selling patented or branded medicines and vaccines, then earning revenue each time those products are purchased and used. Some products are sold directly through distributors and pharmacies, while others are bought in bulk by public health agencies or hospital systems. The company also earns from partnerships, licensing deals, and co-development arrangements with other drug makers. What sets Pfizer apart is its role near the top of the pharmaceutical value chain: it spends heavily on research, clinical trials, regulatory approval, manufacturing, and global distribution, then relies on exclusivity and brand trust to sell medicines at premium prices. This makes it different from generic drug makers, which mostly copy older drugs, and from biotech startups, which often focus on a narrow set of experimental therapies.

Nike Inc

NYSE:NKE

Nike is a global sportswear company that designs and sells athletic shoes, clothing, and equipment. Its best-known products are sneakers, running gear, training apparel, and team sports gear, sold under the Nike and Jordan brands, along with Converse. The company serves everyday consumers, serious athletes, schools, teams, and retailers that want branded sports products people already recognize and trust. Nike makes money mainly by selling products through its own stores and websites, through wholesale partners such as sporting goods chains and department stores, and through licensing deals. It earns most of its sales from footwear, but apparel and equipment also matter. Because Nike controls design, brand image, and product storytelling, it can charge more than many plain-label rivals and use fashion, sport, and celebrity endorsements to drive demand. What makes Nike’s business model different is that it sits at the top of the athletic goods value chain: it does not mainly make things for other brands, it creates the brands shoppers ask for by name. That gives Nike strong control over style, pricing, and distribution. It is both a consumer brand and a sports marketing company, with products that blend performance use and everyday fashion.

Visa Inc

NYSE:V

Visa is a payments network company, not a bank or a card issuer. It connects merchants, banks, and card issuers so people and businesses can pay with debit cards, credit cards, and digital wallets almost anywhere Visa is accepted. Its core job is to move payment messages quickly and securely between the parties in a transaction. Visa does not usually lend money to cardholders or take on credit risk itself. It makes money mainly by charging fees tied to payment processing, card use, and access to its network. Banks and payment companies use Visa’s rails to issue cards and handle transactions, while merchants accept Visa because it reaches a very wide base of consumers and businesses. What makes Visa’s business different is that it sits in the middle of everyday electronic payments. The company earns a toll-like fee each time its network is used, so its role is closer to the payment infrastructure than a retail brand. That makes Visa a key service provider in the flow of money between consumers, merchants, and financial institutions.

Alibaba Group Holding Ltd

NYSE:BABA

Alibaba Group is a Chinese internet company best known for running online marketplaces that connect shoppers, merchants, and brands. Its main retail sites, including Taobao and Tmall, let consumers buy goods from third-party sellers and brands, while Alibaba.com helps businesses source products from suppliers. It also sells cloud computing services through Alibaba Cloud and offers logistics, digital media, and other internet services. Alibaba makes most of its money by charging merchants for advertising, commissions, and service fees on its marketplaces. On the cloud side, it earns money from customers that rent computing power, storage, and software over the internet. Its main customers are online shoppers, small and large merchants, and enterprises that need cloud infrastructure. What makes Alibaba different is that it sits in the middle of a huge online commerce network rather than owning most of the inventory it sells. The company mainly provides the digital storefront, payment flow, traffic, logistics connections, and computing tools that let others do business more efficiently. That makes it both a marketplace operator and a core service provider for China’s internet commerce and cloud ecosystem.

JPMorgan Chase & Co

NYSE:JPM

JPMorgan Chase is a large bank and financial services company. It takes deposits, makes loans, processes payments, and helps people and companies manage money. Its main customers include consumers, small businesses, large corporations, governments, and institutional investors. The company makes money in several familiar banking ways: interest on loans, fees from cards and payment services, charges for investment banking and advisory work, and income from asset and wealth management. It also earns money from trading and market services for clients. That mix gives it exposure to both everyday banking and the needs of major companies that need capital, advice, and global payment networks. What sets JPMorgan Chase apart is its role as a full-service financial middleman. It sits between savers and borrowers, between companies and the capital markets, and between buyers and sellers moving money around the world. That broad reach makes it more than just a retail bank: it is a core utility for payments and lending, and also a major provider of corporate finance and market services.
