Buffett’s 2,600-Year-Old Investing Formula

Nugget by Warren Buffett

Oct 09, 2026

👋 Hey friend,

I’m currently reading the book Buffett and Munger Unscripted.

It’s a compilation (organized by topic) of three decades of investing and business insights from Berkshire Hathaway’s annual shareholder meetings.

In one passage, Buffett explains the essence of investing in just three paragraphs, expanding on a 2,600-year-old saying by Aesop: “A bird in the hand is worth two in the bush.”

I loved that because it makes the whole idea of investing easy to remember, stripping away unnecessary complexity.

In today’s letter, I’m sharing that nugget with you!

🟠 Warren Buffett:
The first investment primer that I know of, and it was pretty good advice, was delivered in about 600 B.C. by Aesop: ‘A bird in the hand is worth two in the bush.’ Incidentally, Aesop did not know it was 600 B.C.—he was smart, but not that smart. Aesop was onto something, but he didn’t finish it, because there’s a couple of other questions that go along with it. He forgot to say exactly when you were going to get the two from the bush, and he forgot to say what the interest rates were that you had to measure this against. But if he’d given those two factors, he would have defined investment for the next 2,600 years.
You will trade a bird in the hand, which is investing—you lay out cash today; then … you have to evaluate how many birds are in the bush, and when they’re going to come out. Now, if interest rates are 5%, and you’re going to get two birds from the bush in five years, that’s much better than a bird in the hand now. If you get them in five years, that’s roughly 14% compounded annually and interest rates are only 5%. But if interest rates were 20%, you would decline to take the two birds in the bush five years from now. It’s not good enough, because at 20%, if I just keep this bird in my hand and compound it, I’ll have more birds in five years.
… Usually people associate “growth” with a lot more birds in the bush, but you still have to decide when you’re going to get them, you have to measure that against interest rates, and you have to measure it against other bushes (opportunity costs). And that’s all investing is: It’s a value decision based on what something is worth, how many birds are in the bush, when you’re going to get them, and what interest rates are.
