Oligopoly vs. monopoly
Two years ago, I published an article that caused a great response: “There are indeed monopoly in this world” Today I plan to change the perspective and talk about some of the more famous oligopolistic companies in the world.
Please note that there is one difference between an oligopoly and a monopoly: a monopoly is basically certain to make money because there is only one company that controls the entire market, but an oligopoly is not necessarily certain to make money because there are multiple companies sharing the market. The best example is the US airline industry. Although it is controlled by a few operators, each of them has suffered heavy losses for a long time.
Strategic Consulting
McKinsey and Boston Consulting Group are two groups that can be said to have monopolized most of the global strategic consulting market, but both companies are private companies.
Accenture also has a small number of strategic consultants, but the business volume is very small. For more details about Accenture, please see my post of “What kind of company is Accenture, the McKinsey of technology industry?“
Commercial aircraft
Boeing (ticker: BA) and Airbus (ticker: EADSY) have long shared the global civil commercial aircraft market. But their days may be numbered, as their biggest common enemy, Commercial Aircraft Corporation of China (Comac), has begun to enter this market. In the future, the global civil commercial airliner market will change from a duopoly of two companies to a trio.
Commercial aircraft engines
The global civil commercial aircraft market has long been monopolized by four companies: Safran (ticker: SAFRF), Pratt & Whitney (ticker: RTX), General Electric (ticker: GE), and Rolls-Royce (ticker: RYCEY). For example, the engines used by COMAC are from Safran, a US-French joint venture.
Regarding General Electric, please see my post of: “How did three listed companies make money after GE spinoff? What are the prospects?“
Cryptocurrency trading
Currently, the two largest cryptocurrency trading platforms are Binance and Coinbase (ticker: COIN). Regarding these two companies; please see the introduction of my post of: “How do Coinbase and Binance make money? Advantages comparison“
Credit card network
Visa (ticker: V) and Mastercard (ticker: MA) are the world’s most famous duopoly.
In Sections 2-3 of my book “The Rules of Super Growth Stocks Investing“, I have introduced in detail the two credit card issuing networks, Visa (ticker: V) and Mastercard (ticker: MA). If you are not very clear about important issues such as the basic business, moat, market share, etc. of these two companies, I suggest that readers refer to the contents of this small chapter in my book.
The following is an article set in my blog about these two credit card issuers:
- “Several possible threats to the Visa and Mastercard credit card networks“
- “What’s the credit card difference among American Express, Visa and MasterCard ? at least 8 differences“
- “American Express, one of the best investments of Buffett’s career“
- “The differences between Visa and Mastercard?“
- “Has the moat of ubiquitous credit card networks loosened?“
Credit ratings of countries and companies
There are only three companies in the world that monopolize this market, as I introduced in Section 2-2 of my book “The Rules of Super Growth Stocks Investing“, the three major corporate credit rating companies that are well-known in the business community and capital markets are Standard & Poor’s (US stock code: SPGI), Moody’s (US stock code: MCO), and Fitch (not listed).
Consumer credit agency
In the field of personal consumers, the United States also has three major consumer credit rating companies (please refer to my post: “Three major consumer credit rating companies Equifax, Experian, and TransUnion“). Their business is to evaluate personal credit ratings. Their status is like Taiwan’s Financial Joint Credit Information Center, China’s Baihang Credit, or Ant Group’s Sesame Credit.
Home mortgage loans in the United States
Fannie Mae (ticker: FNMA) and Freddie Mac (ticker: FMCC) are the first and second largest mortgage lenders in the United States and the largest U.S. franchised companies. Their main business is to acquire loans in the secondary market for U.S. home mortgages and raise funds at a lower cost by issuing agency bonds or securitized mortgage bonds to investors, earning the spread. Fannie Mae’s full name is the Federal National Mortgage Association (FNMA). Freddie Mac was formerly known as the Federal Home Mortgage Corporation (FMCC), both of which are companies sponsored by the US government.
I have introduced them in detail in Sections 2-3 of my book “The Rules of Super Growth Stocks Investing“.
Core semiconductor equipment
There are currently five major semiconductor equipment manufacturers in the world, among which Applied Materials and Lam Research are particularly important. Regarding semiconductor equipment manufacturers, please see my following posts:
- “Top five semiconductor equipment providers“
- “How does Applied Materials, lord of semiconductor equipment, make money?“
- “How does Lam Research, top chip equipment player, make money?“
- “Why was ASML founded?“
- “ASML, who dominate TSMC’s fate“
Photoresist
The global photoresist market is divided among five companies: Japan’s JSR (ticker: JSCPY) (28%), Tokyo Ohka TOK (ticker: TDTH) (21%), Rohm and Haas under Dow Chemical (ticker: DOW) (15%), Shin-Etsu Chemical (ticker: SHECF) (13%), and Fuji Electronics (ticker: FELTF) (10%). Japanese companies account for approximately 70% to 90% of the global photoresist market, especially in the field of high-end ArF and EUV photoresists, where the market share even exceeds 90%.
EDA Electronic Design Automation
There are currently three major EDA electronic design automation manufacturers in the world, namely: Synopsy (ticker: SNPS), Cadence (ticker: CDNS), and Mentor Graphics (ticker: SIEGY) under Siemens. For more information about this EDA electronic design automation manufacturer, please see my following related posts:
- “Three EDA oligopoly vendors: Synopsys, Cadence, and Mentor Graphics“
- “How does, the EDA oligopoly, Cadence make money?“
- “How does Synopsis, the EDA oligopoly, make money?“
Memory Chip
Currently, there are only three major memory manufacturers in the world: Samsung (ticker: SSNLF), Hynix (ticker: HXSCL), and Micron (ticker: MU). In my book “Super Growth Stock Investment Rules”, in the section 3-1 on the third category of industries, I took Micron as an example. Please see my post of “How does Micron make money? What investors should know?“
I have also introduced Samsung in detail in Section 3-3 of my book “The Rules of Super Growth Stocks Investing“.
But now the situation of these three monopolizing the memory market has changed, because China’s Yangtze Memory Technologies (YMTC) has been no less than Amon in terms of technology and market share in recent years. YMTC not only expects to increase its monthly production capacity to 130,000 pieces by the end of 2024, but also plans to challenge 15% of the global NAND Flash production by the end of 2026.
China’s Changxin Memory Technologies (CXMT) will have a monthly production capacity of 280,000 pieces by the end of 2025, and is expected to exceed 300,000 pieces in the future, equivalent to 15% of the global DRAM production.
In short, the good days of the three memory monopolies are over.
