💼 Charlie Munger's Wealth Building Principles

In this paragraph, Charlie Munger, Vice Chairman of Berkshire Hathaway, discusses the concept of generating high annual returns with small amounts of capital. He emphasizes that building real wealth doesn't require a large starting sum and introduces the idea that a few well-chosen opportunities can lead to significant wealth accumulation. Munger shares a lesson from his maternal grandfather, who became the richest man in town by capitalizing on a few opportunities during economic panics. He also criticizes the modern approach of using computer algorithms to exploit market inefficiencies, likening it to leeching and suggesting that those who profit this way should be charitable with their gains. The paragraph concludes with Munger's assertion that there are three key principles to understand for generating high returns on small investments, hinting at the inefficiency of large markets and the opportunities presented by smaller ones.

05:01

🏞 Investing in Inefficient Markets and Capitalizing on Opportunities

The second paragraph delves into the first of Munger's three principles: looking for opportunities in inefficient markets. It explains that while Berkshire Hathaway's size is often seen as an advantage, Munger and Buffett view it as a hindrance to high investment returns due to the necessity of focusing on large, less mispriced opportunities. The narrator suggests that smaller investors can exploit inefficiencies that larger investors overlook. Warren Buffett's strategy of investing in undervalued companies with small capital is highlighted, illustrating how the internet has simplified the process of finding such opportunities. The paragraph advises using a stock screener to filter for small market cap and reasonable PE ratio companies, which are often under the radar of Wall Street analysts, thus increasing the likelihood of finding stocks trading below their intrinsic value.

10:02

🚀 Taking Big Swings and the Power of a Concentrated Portfolio

This paragraph presents the second and third principles from Munger's investing philosophy: taking big swings when a good opportunity arises and not being afraid of a concentrated portfolio. It uses the analogy of baseball and the strategy of the great player Ted Williams to illustrate the importance of patience and selectively investing in opportunities that are 'in the sweet spot.' Munger believes that waiting for the right opportunity and then investing aggressively can lead to high returns. The paragraph also challenges the conventional wisdom of diversification, advocating instead for a concentrated approach where investors focus on a few businesses they understand well. It tells the story of billionaire investor John Ariaga, who made his fortune by focusing exclusively on real estate near Stanford University, demonstrating the power of specialization and concentration in building wealth.

Keywords

💡Charlie Munger

Charlie Munger is the vice chairman of Berkshire Hathaway and a renowned investor known for his wisdom in generating wealth. In the video's theme, Munger's name is central as the script discusses his advice on investing small amounts of money to achieve high annual returns. The script mentions Munger's strategy of focusing on a few opportunities and acting aggressively when the right ones present themselves, which is a key part of his investment philosophy.

💡Annual Returns

Annual returns refer to the profit or loss made on an investment over one year. The video's theme revolves around generating high annual returns, specifically 50%, with small amounts of capital. Munger suggests that with the right strategy and opportunities, it's possible to achieve such high returns, contrary to the common belief that substantial capital is required for significant gains.

💡Inefficient Markets

Inefficient markets are areas where there is a lack of information or analysis, leading to potential mispricing of assets. The script highlights that Munger advises looking into such markets for opportunities because larger investors often overlook smaller, potentially mispriced investments. This concept is crucial to the video's message about finding high-return opportunities with limited capital.

💡Berkshire Hathaway

Berkshire Hathaway is a multinational conglomerate控股公司, headed by Warren Buffett and Charlie Munger, known for its size and investment prowess. The script uses Berkshire Hathaway as an example to illustrate the challenges of generating high returns due to its large size, which forces it to focus on fewer, larger investment opportunities, thus missing out on the inefficiencies available in smaller markets.

💡Market Cap

Market cap, short for market capitalization, is the total value of a company's shares of stock at their current market price. The script suggests using a stock screener to filter for companies with a market cap between 10 million to 200 million, which are often overlooked by larger investors and Wall Street analysts, increasing the chances of finding undervalued stocks.

💡PE Ratio

The PE Ratio, or price-to-earnings ratio, is a valuation ratio calculated by dividing the market value per share by the earnings per share. In the script, it's recommended to set a PE ratio range from 3 to 15 when using a stock screener, as this can help identify companies that are potentially undervalued and present good investment opportunities.

💡Concentrated Portfolio

A concentrated portfolio refers to an investment strategy where a smaller number of stocks are held, often because the investor has a high level of conviction in those particular companies. Munger advocates for this approach, as opposed to diversification, arguing that investors can achieve higher returns by focusing on a few businesses they understand well, as illustrated by his own investment in Berkshire Hathaway, Costco, and a fund managed by Lee Lou.

💡Diversification

Diversification is a risk management strategy that involves spreading investments across various financial instruments, industries, or other categories to mitigate risk. The script challenges the conventional wisdom of diversification by suggesting that concentrating investments in a few well-understood businesses can lead to higher returns, as demonstrated by Munger's own investment strategy.

💡Ted Williams

Ted Williams was one of the best baseball players of all time, known for his discipline in waiting for the right pitch to hit. The script uses Williams as an analogy to explain Munger's investment philosophy, emphasizing the importance of patience and waiting for the right opportunity before making a move, which can significantly increase the chances of success.

💡John Ariaga

John Ariaga is mentioned in the script as an example of someone who became a billionaire through a concentrated investment strategy in real estate near Stanford University. His story illustrates Munger's point about the benefits of focusing on a specific area of expertise and ignoring other opportunities to achieve exceptional results.

play00:00

guess what I just came across a long

play00:02

lost clip of Charlie Munger explaining

play00:04

the three things he would do to generate

play00:06

50 annual returns investing small

play00:08

amounts of money this clip looks like it

play00:11

was shot on an iPhone 4 but it is Monger

play00:13

at his absolute best if you want to

play00:16

build real wealth you need to see it

play00:18

there's an old saying that it takes

play00:20

money to make money this saying may be

play00:22

true but the amount of money you need to

play00:24

get started generating High returns is

play00:25

not as much as many would believe

play00:27

according to Munger now let's get into

play00:29

the video I'm worn and you are known for

play00:33

saying that if you work with a small sum

play00:34

Capital namely you think being 10

play00:36

million dollars Warren how we said that

play00:39

you could guarantee that you compound

play00:41

that a 50 a year so my question is can

play00:44

you provide some examples and I would

play00:46

ask kindly ask you to provide as many

play00:49

examples as possible and be as specific

play00:51

as possible thank you

play00:56

well amen I hear somebody who really

play00:59

wants to get rich

play01:01

at a rapid rate in specifics

play01:05

that is not what we're trying to do here

play01:07

you

play01:09

ought to leave some mystery so that you

play01:10

can

play01:11

give yourself finding your own way

play01:15

you know they've got ideas but I've had

play01:19

a driver quite feel

play01:22

it's a lesson I can give you

play01:25

is a few is all you need and don't be

play01:29

disappointed and when you find the few

play01:33

of course you've got to act aggressive

play01:35

that's the Wonder sister

play01:36

and I learned that indirectly from a man

play01:39

I never met which was my mother's

play01:42

maternal grandfather

play01:45

he was a Pioneer and he came out to Iowa

play01:47

and fought in the blackout Hawk Wars and

play01:50

so on and and eventually after enormous

play01:54

hardship he was the richest man in town

play01:56

and he owned the bank and and so on and

play02:02

he sat there in his old age one my

play02:05

mother knew him because you'd go to

play02:08

his Algona Iowa where he lived and had

play02:10

the big house in the middle of town

play02:12

iron fence capacious Lawns big Barns and

play02:18

what Grandpa Ingham used to tell her is

play02:21

there's just a few opportunities you get

play02:23

in the whole life this guy took over

play02:25

Iowa when the land was the black top

play02:27

soil aisle was cheap

play02:30

but he didn't get that many

play02:31

opportunities it was just a few that

play02:33

enabled him to become proud prosperous

play02:37

he bought a few Farms every time there

play02:39

was a panic you know and he released

play02:42

them to Thrifty Germans he could lose

play02:43

money policing a farm to a German in

play02:45

Iowa and but he only did a few things

play02:50

and and

play02:53

I'm afraid that's the you're not going

play02:55

to find a million wonderful ideas

play02:58

these people the computer algorithm is

play03:00

good but they have a computer that's

play03:01

just in the whole world it's like Placer

play03:03

mining

play03:04

and and of course every end of somebody

play03:08

else comes in the niche starts leeching

play03:10

away

play03:11

and I don't think it's that honorable

play03:14

way to make a living by the way I would

play03:16

rather

play03:17

make my money in some other way to the

play03:19

outsmarting the trading system so I have

play03:22

a little computer algorithm that just

play03:23

leeches or what everybody's trade I

play03:26

always say that those people have all

play03:28

the social utility of a bunch of rats

play03:30

and a granary

play03:33

create a way to make money

play03:35

I would say that if you make your money

play03:36

that way you should be very charitable

play03:38

with it and you've done a lot to atone

play03:39

for

play03:41

and

play03:42

so I don't think it's an ambition we

play03:45

should encourage and the rest of us who

play03:48

aren't just leeching a little off the

play03:50

top because we're great at computer

play03:52

science

play03:54

and that's what this room was full of

play03:56

and if you're not finding it harder now

play03:58

you don't understand it

play04:02

that's that's my lesson there are three

play04:05

important principles you need to

play04:06

understand if you want to follow

play04:07

munger's advice on generating High

play04:09

Returns on small sums of money the first

play04:12

principle is to look in the inefficient

play04:14

markets Monger is the vice chairman of

play04:16

Berkshire Hathaway and as of the making

play04:18

of this video Berkshire has a market cap

play04:20

approaching 800 billion dollars that

play04:23

makes Berkshire the ninth largest

play04:24

company in the world by market cap and

play04:26

the biggest non-tech US company in the

play04:29

world to most people berkshire's massive

play04:31

size would seem like a huge Advantage

play04:33

when it comes to investing right well

play04:35

actually that's not the case Charlie and

play04:38

Warren have repeatedly said that

play04:39

Berkshire size is an impediment to

play04:41

generating High investment returns

play04:42

because Berkshire has so much money

play04:44

Warren and Charlie are forced to only

play04:46

focus on large investment opportunities

play04:48

the odds of these large investment

play04:50

opportunities being mispriced or to use

play04:52

an investing term inefficient or

play04:55

extremely low on the other hand there is

play04:57

a much higher probability of an

play04:59

inefficiency occurring when the size of

play05:01

the investment is much smaller large

play05:03

investors like are too busy paying

play05:05

attention to bigger opportunities to

play05:07

even notice these small opportunities

play05:09

this is where your opportunity comes in

play05:12

listen to Charlie wunger's business

play05:13

partner Warren Buffett explain this

play05:16

concept I was working with a tiny tiny

play05:18

tiny amount of money

play05:20

and so I would pour through volumes of

play05:23

businesses and I would find one or two

play05:26

that I could put ten thousand dollars

play05:28

into or fifteen thousand dollars into

play05:29

that was just ridiculous they were

play05:32

ridiculously cheap and obviously as the

play05:34

money increased uh the the universe of

play05:38

possible ideas started shrinking

play05:40

dramatically when Warren and Charlie

play05:42

were investing small sums of money

play05:44

decades ago they had to spend thousands

play05:46

of hours pouring through tens of

play05:48

thousands of pages of financial reports

play05:50

to find just one potential idea

play05:52

thankfully for us the internet has made

play05:54

sourcing potential mispriced stocks a

play05:56

heck of a lot easier all you have to do

play05:59

is jump to a stock screener like this

play06:01

one here and you don't need anything

play06:02

fancy a free screener like this will do

play06:05

just fine all you need is a screen that

play06:07

can filter by market cap and PE ratio

play06:09

set the market cap range to 10 million

play06:11

to 200 million and the p e ratio range

play06:14

from 3 to 15. the companies that meet

play06:17

this criteria will be small by Wall

play06:19

Street standards most professional

play06:21

investors have restrictions around

play06:22

investing in stocks below a certain

play06:24

market cap for example the fund I work

play06:26

at in New York City has a rule in place

play06:28

that makes it so you can invest in any

play06:30

company below a 5 billion dollar market

play06:32

cap this restriction means tons of

play06:34

potentially great Investments slip by us

play06:36

because these companies are simply too

play06:38

small additionally companies of this

play06:40

size likely are uncovered by Wall Street

play06:42

analysts compare that to a company like

play06:44

Apple Apple stock is covered by 31 Wall

play06:47

Street analysts that monitor the

play06:48

company's every move the fact that

play06:50

virtually nobody is paying attention to

play06:52

these small companies increases the

play06:54

probability that you can find a stock

play06:56

that is trading well below its intrinsic

play06:58

value before we get to lesson number two

play07:00

make sure to hit that subscribe button

play07:02

because it is so important to get the

play07:04

teachings from people like Charlie

play07:05

Munger to as large of a group as

play07:07

possible learning from monger and other

play07:09

investing Legends really positively

play07:11

impacted my life and I know it can do

play07:14

the same for you so the next lesson for

play07:16

Monger is take big swings when a good

play07:18

opportunity comes along the logic being

play07:20

that great opportunities are rare So

play07:22

when they do come along you have to take

play07:24

full advantage this point can be

play07:27

demonstrated by using an analogy from

play07:28

the sport baseball for my non-us viewers

play07:31

baseball is a bad and ball sport played

play07:33

on a field by two teams against each

play07:35

other in baseball a play around 1 team

play07:37

throws a small round ball at a player on

play07:39

the other team who then tries to hit it

play07:41

with a bat the goal of the batter is to

play07:43

hit the ball in such a way that it will

play07:45

allow his team to score runs AKA points

play07:48

according to Munger there are some

play07:50

lessons from the game of baseball that

play07:51

can help you make money in the stock

play07:52

market one of the best baseball players

play07:55

of all time was a man named Ted Williams

play07:57

Williams wrote a book called the science

play08:00

of hitting it contains a compelling

play08:02

illustration of him at bat with the

play08:03

strike zone divided into 77 distinct

play08:06

squares Williams recognized that by

play08:08

waiting for a pitch in his sweet spot

play08:10

significantly increased his chances of

play08:12

getting a hit being patient and waiting

play08:14

for the right opportunity offered a 40

play08:16

hit rate impatience on the other hand

play08:18

could lower his success rate to a mere

play08:20

23 to 25 percent Williams understood

play08:23

that average batters turned into great

play08:24

ones if they waited for the right pitch

play08:26

and even the best batters turned into

play08:28

average ones if they swung at the wrong

play08:30

pitch Monger is a big believer that this

play08:33

concept also applies to investing as an

play08:36

investor each day you are faced with

play08:37

thousands of potential Investments think

play08:40

of these as the pitches in baseball in

play08:42

order to invest successfully you have to

play08:44

be waiting to sit patiently with your

play08:45

bat on your shoulder watching pitch by

play08:47

pitch go by only when you see an

play08:50

investing opportunity that is perfectly

play08:51

in your sweet spot do you swing the

play08:54

problem is though that these perfect

play08:55

pitches aren't all that common in

play08:57

investing it can be months or even years

play08:59

before you finally get one that is why

play09:01

when the perfect pitch does finally come

play09:03

you better make the most of it and swing

play09:05

for the fences this ties perfectly into

play09:07

the third lesson for Monger don't be

play09:10

afraid of a concentrated portfolio

play09:12

conventional investing wisdom states

play09:14

that investors should have highly

play09:15

Diversified portfolios or put another

play09:18

way people should have portfolios that

play09:20

consist of dozens if not hundreds of

play09:22

stocks Munger believes that's incredibly

play09:24

foolish if your goal is to generate High

play09:26

investment returns Munger has the vast

play09:28

majority of his family's entire net

play09:30

worth in just three Investments

play09:31

Berkshire Hathaway stock Costco stock

play09:34

and a fund managed by an investor named

play09:36

Lee Lou instead of favoring

play09:38

diversification Munger advocates for a

play09:41

concentrated approach where investors

play09:43

focus on a handful of outstanding

play09:44

businesses they thoroughly understand he

play09:47

believes that by closely examining and

play09:49

comprehending these businesses investors

play09:51

can make more informed decisions

play09:52

resulting in a higher likelihood of

play09:54

achieving exceptional returns Munger

play09:57

uses the story of his friend John Ariaga

play09:59

to demonstrate the point John Ariaga is

play10:02

a billionaire investor naturally it

play10:04

would be fair to assume that since

play10:06

Ariaga is a billionaire his net worth

play10:08

would consist of many different types of

play10:10

assets maybe he has a few businesses he

play10:12

owns and a countless number of stocks

play10:14

while this may be a natural assumption

play10:16

it couldn't be further from the truth

play10:18

and you'll see why in just a second John

play10:20

Ariaga made his fortune in real estate

play10:22

real estate in its own right is a very

play10:24

broad asset class there are many

play10:26

different types apartment office

play10:28

industrial single-family houses Self

play10:30

Storage additionally there's a near

play10:33

infinite number of locations where this

play10:34

real estate can be located the United

play10:36

States is just one of these countries to

play10:38

pick from just within the United States

play10:40

there are 387 what are referred to as

play10:43

Metropolitan statistical areas think of

play10:46

this as different real estate markets

play10:48

and then within each of these

play10:49

Metropolitan statistical areas there are

play10:52

countless numbers of neighborhoods from

which to choose from the point here

play10:55

being that even within real estate there

play10:57

are so many ways investors can diversify

play10:59

a portfolio John Ariaga decided to take

play11:02

a different approach he was going to be

play11:04

super concentrated in building his

play11:06

fortune he was only going to buy real

play11:08

estate located within one mile of the

play11:10

campus of Stanford University in

play11:12

California over a 40-year period

play11:14

allariaga did was never put down a lot

play11:16

of debt and when things went down he

play11:18

bought and when everyone got euphoric he

play11:20

sold that's all he did I guarantee as

play11:24

ariago was building his billion dollar

play11:25

Fortune he was offered investments in

play11:27

things outside of just that one mile

play11:29

distance from Stanford's campus for all

play11:31

intents and purposes Ariaga ignored all

play11:34

other investment opportunities to focus

play11:35

on what he knew best Arya willingness to

play11:38

stick to what he knew best and as a

play11:40

result have a massive advantage over the

play11:42

competition led him to being one of the

play11:44

wealthiest people in the world
