From Omaha to Los AngelesFrom a grocery store boy to the world’s most famous investing partner

Munger grew up in Omaha and worked at the Buffett family’s grocery store long before he actually met Warren decades later. He never finished his bachelor’s degree because of the war, but still got into Harvard Law and became a successful lawyer in Los Angeles

The 1950s were very hard for him, bringing a divorce and the loss of a son. After meeting Buffett in 1959 he gradually turned from law to investing. Tap each year to follow his journey

LIFE · ALMANACKMunger’s life calendar

CASE FILE · 1965–1972From cigar butts to wonderful businesses
Buffett’s old approach

Buy ordinary businesses at very cheap prices

  • Like picking up a cigar butt with one puff left: you profit only once
  • You have to keep selling and finding new ones
  • Bad businesses often get worse while you wait
What Munger argued for

Buy wonderful businesses at fair prices

  • The business grows on its own with little extra capital
  • You can hold for a long time and let profits compound
  • See’s Candies in 1972 was the first clear test

In Berkshire’s 50th anniversary letter, Buffett said Munger persuaded him to change his approach, and called Berkshire built to Charlie’s blueprint, with himself as the general contractor (paraphrased)

Munger in a 2009 BBC interview

If you can’t calmly accept a 50% fall in your stock, which can happen two or three times a century, you’re not fit to be a shareholder and deserve the mediocre result you’ll get

Paraphrased, not a direct quote

Partnership ledgerLab: could you have held on to Munger’s fund?

The Wheeler, Munger fund beat the Dow by a mile over 14 years, but the ride was anything but smooth. The figures below are the real annual returns. Choose the year you start investing, and set a rule: if a year loses more than a certain amount, you can’t take it any more and move your money to the Dow instead

Annual returns (%)
100 from your starting year
Wheeler, MungerDowYour money
Your 100—
If you held the fund without selling—
If you held the Dow throughout—
Your deepest decline—

The fund’s annual returns before the manager’s share, and the Dow, from the table Buffett published in The Superinvestors of Graham-and-Doddsville (1984). Limited partners compounded about 13.7% a year after the manager’s share. Moving to the Dow is a lab assumption. Taxes and fees are excluded

What this means for traders

Even a good trading system has losing streaks. If your order size is so big you can’t stand it, you’ll abandon the system at the worst moment and miss the recovery. The right order size is one where you can still follow your rules even when the account falls hard

The dream businessLab: why was See’s a dream business?

In 1972 See’s made less than $5 million in pre-tax profit and used about $8 million of capital. Buffett and Munger paid $25 million, because the business could grow with almost no extra capital, so nearly all its profit could be sent elsewhere to reinvest. Compare it with businesses that need extra capital every time they grow

Final year profit (million)—
Cumulative profit (million)—
Extra capital (million)—
Cash available to reinvest—

A simple model: pre-tax profit grows at a constant rate each year, and the capital needed rises with the extra profit at a set ratio. Taxes and inflation are excluded. Real figures from Buffett’s 2007 letter: See’s made about $82 million pre-tax in 2007 and about $1.35 billion cumulatively since 1972, using only $32 million of extra capital, while an ordinary business earning $82 million would need about $400 million of capital

Lollapalooza scannerLab: catch the bias before it catches you

In 1995 Munger explained that smart people make bad decisions because of psychological tendencies everyone has, and when several tendencies act together, the effect is more extreme than expected. He called this Lollapalooza. Read each trading situation, then pick the biases you think are at work

Gold soaring in every group chat Gold has risen 5 days in a row. Every group chat talks only about gold, and friends post their profit screenshots every day. You have no order yet and feel you must rush in before it’s too late

Which biases are at work? Pick as many as you like

You’ve picked 0 biases

The tendency names are shortened from the 25 tendencies in The Psychology of Human Misjudgment as printed in Poor Charlie’s Almanack. The situations are hypothetical examples. The answer is the most prominent set of biases, not the only possible answer

What this means for traders

Munger used a pilot’s-style checklist before big decisions. Traders can do the same. Before opening an order, ask yourself 3 questions: am I entering because others are? Am I trying to win back a loss? And if I’m wrong, where will I get out?

Fact checkFact check: truth and stories passed along

Munger’s sayings and stories have been shared so widely that some have become distorted. We sort each one by the weight of the evidence

1948Common misconceptions

Munger finished a bachelor’s degree before law school

He studied mathematics at the University of Michigan but left to serve in the war. Harvard Law admitted him without a bachelor’s degree, and he graduated in 1948 with honours

1965Supported

Munger changed Buffett’s investing approach

Buffett himself wrote in Berkshire’s 50th anniversary letter that Munger persuaded him to stop buying ordinary businesses cheaply and buy wonderful businesses at fair prices, and said Berkshire was built to Charlie’s blueprint

1973–1974Common misconceptions

Munger’s fund never suffered big losses

It lost 31.9% and 31.5% two years in a row, a decline of about 53% from the peak, and did worse than the Dow in both years

1962–1975Partly true

Investors in the fund earned 19.8% a year

19.8% is the fund’s total return before the manager’s share. Limited partners compounded about 13.7% a year, still far above the Dow’s roughly 5%

His whole lifeCommon misconceptions

Invert, always invert are Munger’s own words

Munger borrowed this advice from Carl Jacobi, a Prussian mathematician, and applied it to decisions, such as asking what would cause failure and then avoiding it

1972Supported

See’s was bought for far more than the capital the business used

They paid $25 million while the business used about $8 million of capital. Buffett wrote in 2007 that See’s had earned $1.35 billion in cumulative pre-tax profit using only $32 million of extra capital

2008Partly true

Munger discovered BYD

Munger was the one who pushed Berkshire to invest, but Li Lu, founder of Himalaya Capital, introduced him to the company and its founder Wang Chuanfu

2009Supported

Shareholders must accept prices falling by half

In a 2009 BBC interview he said that if you can’t accept your stock falling 50% two or three times a century, you’re not fit to be a shareholder (paraphrased)

LessonsLessons for Forex and gold traders

Your checklist
0/4
01

Invert before you open an order

First ask what would blow up your account, such as excessive leverage, no stop loss or trading on emotion, then cut those out. Munger once said something like: all I want to know is where I’m going to die, so I’ll never go there

02

Wait for the right moment, then act decisively

Munger made his money from a few very good decisions, not frequent trading. Traders don’t need an order every day; a day with no setup is a day you don’t need to trade

03

Know your own biases

Before clicking to open an order, check whether you’re following others, unable to bear a loss, or trusting a famous name without thinking. If several apply at once, be extra careful

04

Prepare for losing stretches

Even Munger’s fund fell about 53% in 1973–74. Use an order size you can bear in bad times, or you’ll be forced out at the worst moment

FAQFrequently asked questions

Who is Charlie Munger?

An American investor and lawyer (1924–2023), vice chairman of Berkshire Hathaway from 1978 until his death, and Warren Buffett’s partner, who persuaded Berkshire to buy wonderful businesses at fair prices

What is the latticework of mental models?

An idea Munger described in 1994: you should have the key thinking models from many disciplines, such as mathematics, accounting, physics, biology, psychology and economics, and use them together instead of seeing every problem through a single tool

What does Invert, always invert mean?

Advice Munger borrowed from the mathematician Carl Jacobi: solve hard problems by turning the question around. For example, instead of asking how to get rich, ask what would blow up your account, then avoid that

What is the Lollapalooza effect?

Munger’s term for situations where several psychological tendencies act together and reinforce each other, so the result is more extreme than the sum of each one alone, such as fear of missing out, following the crowd and envy in a hot market

How can Forex and gold traders use Munger’s ideas?

Use inversion to set rules that prevent heavy losses, run a bias checklist before opening an order, trade only setups you truly understand, and use an order size that can withstand a losing streak
