Inside Warren Buffett’s Brain
What springs to mind when you think of legendary investor Warren Buffett?
For some, it’s his humble Omaha origins or his long-lasting obsession with Coca-Cola. For other people, it’s Buffett’s impeccable investing track record and extraordinary wealth that make a lasting impression.
While these are all legitimate connections to make with the Buffett name, perhaps he is most synonymous with the discipline of value investing – the style and mindset Buffett has made famous over the decades.

Part 2: Inside Buffett’s Brain
Today’s infographic provides a deep dive into Warren Buffett’s brain, and it explains everything about his investing philosophy, along with the framework he uses to evaluate potential opportunities.
It’s the second part of the Warren Buffett Series, which we’ve done in partnership with finder.com, a personal finance site that helps people make better decisions – whether they want to jump on the cryptocurrency craze or follow Buffett’s more traditional path to financial success.

Warren Buffett’s investment philosophy is well-known.
He famously focuses on the intrinsic value of companies, and he buys stocks when they are “on sale”. Buffett’s not afraid to accumulate big positions in companies he likes – and his favorite holding period is “forever”.
While this formula may seem simple on paper, it’s extremely nuanced and complex in practice.
How Does Buffett’s Brain Work?
Warren Buffett has said that he borrows 85% of his investing style from Benjamin Graham, and 15% from Phil Fisher.
Benjamin Graham:
The godfather of value investing gave Buffett a framework for finding undervalued assets and companies.
Phil Fisher:
The famous growth investor showed Buffett the importance of investing with good management teams.
According to writer Robert Hagstrom, Buffett applies these ideas by focusing on four key principles of investing:
1. Analyze a stock as a business
Have the priorities of a business owner and look the company from a long-term perspective.
Is it increasing its intrinsic value? Would you want to own the entire company?
2. Ensure a “margin of safety”
Buffett considers “margin of safety” the three most important words in investing.
In other words, does a company have more intrinsic value than book value?
3. Manage a focused portfolio
Concentrate on a few stocks that will provide above-average returns over time. Buffett suggests investors think of this as owning a “punch card” with just 20 investment choices that can be made over a lifetime.
4. Protect yourself from Mr. Market
Mr. Market can be speculative and emotional, and he should not be relied upon as a predictor of future prices.
Instead, take advantage of Mr. Market periodically, whenever there is a fire sale.
Buffett’s Investment Criteria
Here are 12 key factors Warren Buffett considers when looking at potential opportunities:
1. Simplicity
Is the business easy to understand?
2. Operating History
Has the business been around for a long time, with a consistent operating history?
3. Long-Term Prospects
Is there reason to believe that the business will be able to sustain success in the long-term?
4. Rational Decisions
Is management wise when it comes to reinvesting earnings or returning profits to shareholders as dividends?
5. Candidness
Does the management team admit mistakes? Are they honest with shareholders?
6. Resisting the “Institutional Imperative”
Can the company resist temptations created by institutional dynamics, such as imitating peer companies, or resist changes in direction?
7. Profit Margins
Does the company have high profit margins?
8. Return on Equity
What is the return on equity (ROE) of the business?
9. Owners Earnings
What is the company’s ability to generate cash for shareholders, who are the residual owners? This is technically defined as free cash flow to equity (FCFE).
10. One Dollar Premise
For every dollar retained from net income, does the company create at least one dollar of market value?
11. Intrinsic Value
What is the value of the future owners’ earnings, discounted back to the present?
12. Margin of Safety
What’s the chance you’ll lose money on the stock, in the long run, if you buy it at today’s price?
Or to sum all of these ideas up succinctly, here’s a quote from the man himself.
My strategy is to find a good business – and one that I can understand why it’s good – with a durable, competitive advantage, run by able and honest people, and available at a price that makes sense.
– Warren Buffett

Which Companies Make Up the “Magnificent Seven” Stocks?
FAANG is dead… meet the ‘Magnificent Seven’ stocks that now make up over 25% of the S&P 500.

Which Companies Make Up the “Magnificent Seven” Stocks?
In 2013 CNBC analyst Jim Cramer popularized “FANG,” comprised of Facebook (now Meta), Amazon, Netflix, and Google (now Alphabet), as a shorthand for the best performing technology stocks on the market. Apple, added in 2017, made it FAANG.
However, over the last year a new moniker given by Bank of America analyst Michael Hartnett highlights the most valuable and popularly-owned companies on the American stock market: the “Magnificent Seven” stocks.
We visualize the Magnificent Seven’s market capitalization and 5-year stock performance as of November 2023 using data from Google Finance and CompaniesMarketCap.
The Magnificent Seven Stocks by Market Cap and 5-Year Return
The Magnificent Seven stocks are megacap companies focused and capitalizing on tech growth trends including AI, cloud computing, and cutting-edge hardware and software.
Four of the five FAANG stocks retain their place amongst the Magnificent Seven, with newcomers Nvidia, Tesla, and Microsoft joining the group. Following a poor 2022 performance and having more difficulty capitalizing on tech trends, Netflix is the sole FAANG company not included.
Here’s a look at the companies ranked by their market capitalization on November 6, 2023, alongside their 5-year stock performance:
Rank | Company | Market Cap | 5 Year Performance |
---|---|---|---|
1 | Apple | $2.8 trillion | +250% |
2 | Microsoft | $2.6 trillion | +224% |
3 | Alphabet | $1.6 trillion | +141% |
4 | Amazon | $1.4 trillion | +63% |
5 | Nvidia | $1.1 trillion | +783% |
6 | Meta | $811 billion | +118% |
7 | Tesla | $690 billion | +829% |
The Magnificent Seven make up more than one-quarter of the S&P 500 and more than half of the Nasdaq 100.
Meanwhile, five of the seven are part of the rare trillion dollar club, with Nvidia being the most recent entry.
A common theme among the Magnificent Seven is their ability to collect vast amounts of customer data, create cutting-edge hardware and software, as well as harness the power of AI.
However, if Netflix gets back on track—recently announcing its new ad-supported membership tier has 15 million subscribers—we could soon see a “Magnificent Eight.”
