Warren Buffett is the most successful investor who has ever lived, and he has spent sixty years explaining, in plain English, exactly how he does it. Almost nobody copies him. Not because it is secret, but because it is hard in a way that has nothing to do with intelligence.
From 1965 to 2024, his company Berkshire Hathaway compounded at 19.9% a year while the S&P 500 managed 10.4%. That gap sounds small. Over sixty years it turned a $1,000 stake into about $55 million, against roughly $391,000 in the market.
Here is how he actually picks stocks, and the one advantage behind all of it that you can start copying today.
Berkshire compounded at 19.9% a year versus the S&P's 10.4%, 1965-2024. A small gap in rate, a staggering gap in money.
The 60-Second Version
Buffett compounded about 19.9% a year for 60 years, nearly double the market's 10.4%.
His method: buy wonderful businesses, with durable moats, at a sensible price, and hold for a very long time.
He invests only inside his circle of competence, and always demands a margin of safety.
His real edge is not IQ. It is patience: the overwhelming majority of his fortune came after he turned 65.
He buys businesses, not tickers
Start with the mindset, because everything else follows from it. Buffett does not buy stocks. He buys businesses, in fractional amounts, through the stock market. A share is not a squiggle on a chart. It is part ownership of a real company that earns real money.
So he asks a business owner's questions. What does this company actually earn? Will it earn more in ten years? How sure am I? This is the heart of value investing: the price is what you pay, the value is what you get, and the two are often very different things.

Learn to Analyze Stocks the Way Buffett Does
Reading a business, estimating its value, and demanding a margin of safety is a trainable skill, not a gift. Our Equity Research course walks through the whole process on real companies, step by step.
The four filters
Buffett has described, many times, the screen a company must pass before he will buy it. In his own words it comes down to four things.
A business he understands. He stays inside his circle of competence and simply skips what he cannot judge, however exciting it looks.
A durable competitive advantage. He wants an economic moat, a structural edge, a brand, a network, a cost advantage, that protects profits from competitors for decades.
Honest, able management. People he trusts to run the business and allocate its cash well.
A sensible price. The price must be reasonable against his estimate of the company's intrinsic value.
Notice what is missing: no macro forecasts, no chart patterns, no predictions about interest rates. Just a good business at a fair price, run by good people.
Wonderful company, fair price
Early on, taught by Benjamin Graham, Buffett bought cheap, mediocre companies, cigar butts with one last puff left. His partner Charlie Munger changed his mind, and it made him a fortune.
The line that captures the whole philosophy. 'It is far better to buy a wonderful company at a fair price than a fair company at a wonderful price.' A great business compounds your money for decades. A cheap bad one just sits there. His purchases of See's Candies and Coca-Cola, wonderful businesses held for the very long term, are the textbook cases, and the kind of judgment we teach on real companies in our equity research course.
The margin of safety
Even a careful analyst is often wrong. Buffett's protection against that is the idea he calls the three most important words in investing: margin of safety.
Never pay your full estimate of value. If you think a business is worth 100, you try to pay 70. That gap is your buffer for the things you got wrong, the surprises, the bad luck. It does not guarantee a good outcome, but it stacks the odds in your favor and keeps a single mistake from being fatal. Almost every serious loss in investing traces back to someone paying full price, or more, for a story.
The real secret: patience and compounding
Here is the part people skip, because it is the least glamorous and the most important. Buffett's genius is not that he earns 19.9% in a year. It is that he has done it for sixty years, and mostly left the money alone to compound.
Buffett's net worth barely moved for decades, then erupted. The returns are impressive. The time is the miracle.
Time is the ingredient nobody wants to hear about. Compounding does almost nothing for years, then everything at once. Buffett did not become a billionaire until his mid-50s. The overwhelming majority of his wealth arrived in his 70s, 80s, and 90s, simply because he let good businesses keep working. Most investors never see this, because they cannot sit still long enough to let it happen.
What you can actually copy
You will not match his returns. Almost no one will. But the method is not a secret, and every piece of it is copyable.
Think like an owner. Ask what the business earns, not what the price is doing this week.
Stay in your circle of competence. There is no penalty for skipping what you cannot judge.
Insist on a margin of safety. Leave room to be wrong.
Then be patient, to a degree that feels almost boring. That is where the real money is made.
None of it requires genius. It requires temperament, and the willingness to do simple things for a very long time.

Blu Dot surpasses 2,000% ROAS with self-serve CTV ads
Home furniture brand Blu Dot blew up on CTV with help from Roku Ads Manager. Here’s how:
After a test campaign reached 211,000 households and achieved 1,010% ROAS, the brand went all in to promote its annual sales event. It removed age and income constraints to expand reach and shifted budget to custom audiences and retargeting, where intent was strongest.
The results speak for themselves. As Blu Dot increased their investment by 10x, ROAS jumped to 2,308% and more page-view conversions surpassed 50,000.
“For CTV campaigns, Roku has been a top performer,” said Claire Folkestad, Paid Media Strategist, Blu Dot. “Comping to our other platforms, we have seen really strong ROAS… and highly efficient CPMs, lower than any other CTV partner we've worked with.”
Using Roku Ads Manager, the campaign moved from a pilot to a permanent performance engine for the brand.
