Rate this book
Traduzido em 12 países, esta obra continua a ser uma ferramenta essencial para quem quer dar os primeiros passos na área financeira. O seu conteúdo está dividido em duas partes; a primeira será de iniciação “A arte da Buffettologia básica”, onde pode aprender alguns dos segredos de Buffett e como reconhecer uma empresa onde deve investir. Na segunda parte “Buffettologia Avançada”, tem acesso a outros instrumentos mais evoluídos nomeadamente como determinar a taxa de rendibilidade anual esperada.

Depois de ler os 47 capítulos pode tornar-se facilmente num “buffettologista”, o que os autores identificam como estudiosos das técnicas desenvolvidas por Warren Buffett. Como é defendido no segundo capítulo: “o objectivo deste livro é traçar, passo a passo, a base da filosofia de Warren, de modo a que o leitor possa aplicar os conhecimentos na prática desta disciplina”.

Os autores deixam ainda um conselho: “muitos dos leitores pensam que para chegarem a ricos têm de ganhar bastante dinheiro do dia para a noite. Não é verdade. Apenas é necessário obter uma rentabilidade anual acima da média durante um longo período de tempo”.

Um desafio a não perder para aqueles que admiram ou querem conhecer melhor a filosofia deste investidor que faz parte da lista dos “homens mais ricos do mundo”.

If you are looking for some ground-breaking Buffett investment revelation in this book, you'll be disappointed. But if you follow Warren Buffett, then you know that very little of his investment philosophy is truly ground-breaking, but that's the point. It's simple, but difficult to apply.

What you will find in this book is what I have found to be difficult to find elsewhere. This book essentially combines the qualitative investment philosophy that Warren talks about a great deal about publicly with the quantitive aspects he rarely talks about directly. And it does a pretty good job of combining these two worlds.

The discussion of Warren's qualitative approach is nothing new if you've heard any of Warren's talks or if you've read any of his shareholder letters. I think some of the phrases might have been lifted straight from the letters.

As I expected before I read this book, Warren's technical approach is just as simple as his qualitative approach. The “unexplained techniques" are essentially math functions that you would pick up in a finance class. Let me be clear, that's not a bad thing. It's almost reassuring to find that Warren is as consistent with his technical strategy as he is with his qualitative strategy.

One downside of this book is having been published in 2000, some of the case studies featured in this book turned out to be pretty bad businesses. For example, the author features Freddie Mac, which Warren was an investor, but this book was written before he sold his stock and got out of the business before the housing crash. Also, the author suggests Bear Stearns as a possible "Warren investment company." Hindsight is always 20/20.

A beginners guide to value investing
21 April 2014

I just clicked on Mary Buffett's name on Goodreads and discovered that she is actually the author of quite a large number of books, and each of those books has the name 'Warren Buffett' somewhere in the title (though in reality there are only four books). To be honest with you I am not really sure who Mary Buffett is because she is not one of Warren's children, nor is she his ex-wife (who is dead, by the way) but from what I can remember when I read this book she is connected to him somehow (if not simply using his name to make it appear that she is connected with the self-made billionaire so as to sell more books).

What this book does is that it explores Warren Buffett's strategy of investing in companies that are undervalued, a term known as value investing, at a point in time when the company is going 'cheap': when the value of the shares in the company are significantly less than the actual value of the company. The problem is trying to work out whether a company is undervalued or not, and also having the spare capital to invest. Warren's strategy has worked for him, which is why he is now a billionaire, however we must remember that there was also a lot of luck and guess work on his side.

The issue that I had with this book was, well, first of all it suggested that I wanted to be a billionaire, which, well, I don't because, well, I really do not think that having lots of money is really going to make my life any better (though having money would be a benefit because it means that I could quit my job and then go back to university and self-fund my way through it, which at this stage I cannot). The other issue that I have with the book was the calculations that were being put forward, and these were using a term call 'future value' which is a vague figure at some point in the future which only comes about through predictions and speculations. My biggest issue with the market is that it tries to make concrete some future point that may not come about, yet people will hold onto those suppositions as if they were true.

There are a lot of theories that abound as to how the market works, and my theory is basically that it doesn't. In fact my theory is that the stock market is nothing more than a mathematical illusion that exists simply because we want to believe that it exists and is efficient because we want to believe that it is efficient. In fact, the whole basis of the market is that it exists on confidence, and if nobody had any confidence in the market then the whole system would collapse. In fact this has come about numerous times, and they usually end up with names like Black Friday, Black Tuesday, well, actually any day with the world black in front of it. The sad thing is that when a market (or even a particular stock) crashes in that way it is usually us poor sods that are left standing around holding our dicks in our hands as the wealthy elite run off with all of our money, and all that we are left with are a bunch of worthless pieces of paper.

That is all a share is, and in a way it is no longer even that, and that is a piece of paper that represents ownership in a company, (and also the right to vote at an annual general meeting). In the end if that company collapses in a heap of debt, then in that piece of paper (or the representation of that piece of paper) is absolutely worthless. However, the problem is that we need to prepare and we need to use our resources wisely, which means investing it in as many ways as possible, whether it be through a superfund, or directly as I tend to do it (because getting money out of a superfund, even when you are entitled to it, can be nigh impossible – just ask the guy that sits next to me at work).

I figure the only reason it sells is that people like me are curious if the author -- being Buffett's daughter-in-law -- can provide insights not available elsewhere. In this regard, and almost every other, the book was a miserable failure. All the true advice in the book is pretty obvious and better available elsewhere.

Very poorly written overall. Perhaps the most annoying tic is to ascribe Corporate Finance 101 ideas to Mr. Buffett. This would be like a book about a physicist, let's call him Mr. Smith, believing in gravity. "Mr. smith believes that gravity is a force that attracts objects in relation to their mass." the key ideas of the book are merely asserted, backed up with one example or anecdotes. Contradictory ideas are not explained.

I picked up this little book Buffettology last year in early 2016. At the time I had probably already passed the 30+ mark for the number of books I had read about value investing. Once you’ve read Hagstrom, Lowenstein, Graham, Greenblatt, Janet Lowe, Schroders, you pretty much know what that is all about.

I had also read by then a couple of other books from Mary Buffett (The Oracle’s ex-daughter in law, his son’s Peter ex-wife). She wrote several. This one will remind you, that when buying great businesses, it’s all about having a durable competitive advantage, a long product life ahead, with little change, little disruption probability, little capex requirement, so in other words tons of free cash flow. If you can buy this business when the price is fair or even better, when it’s cheap, then you never need to sell.

If you are a beginner that’s a great book but if you have read quite a bit already on value investing like I did, then that’s the usual stuff that you already know. Nevertheless, this book had some impact on me. Since it was written in 1999, already 18 years ago, it made me realize that on the topic of value investing, everything has already been written many times over and since many years already.

And yet, despite all the information available out there, the public keeps speculating, keeps falling into wall street’s marketing traps, and keeps ignoring the evidence that value investing works.

WB LOOKS FOR COMPANIES WITH ROE >15%

Other peoples folly and WB's discipline are the key to his success.

The intrinsic value of an investment is the projected annual compounding rate of the return the investment will produce.

Without some predictability of future earnings any calculation of future value is mere speculation.

Buffett got the idea of a concentrated portfolio and a circle of competence from Keynes.

Graham would only invest in companies whose projected return was 25% pa +.

Sometimes stocks WB buys increase to above intrinsic value but WB doesn't sell as its intrinsic value is growing faster than the rest of the market.

Average ROE in the US is 12%.

Be wary of companies with consumer monopolies making acquisitions.

Predictable product, predictable profits.

No-one ever went broke selling at a profit. No-one every got really wealthy that way either.

If you buy a stock on 25x with a ROE of 33% your initial investment may be earning just 4% but the retained earnings are earning 33%. Pay a steep price to get in the door but once your in its bliss and the longer your stay the better it gets.

There are some good points in this book, like not forgetting about taxes and inflation, which most people do not consider in their calculations when determining if they made a profit. But there are also some misses. I read the dutch translation which was sloppy here and there and I don't know if the original has the same problems. The greatest flaw in my opinion was that some of the calculations are repeated a few times too many and also that the formula's aren't provided.

I liked it but would only recommend it to beginner-investors who want to get more serious about investing. The more serious investors should already know and do this stuff.

A very good review (although they graded it way to high in my opinion) can be read here:

In this case it might be helpful to know that I work at a stockmarket-helpdesk for independent investors of one of the biggest banks in The Netherlands.

A couple of years ago, I read the first couple of chapters of the Intelligent Investor, and when I heard about this from a friend I was hesitant as I was afraid this would be too technical also. But that wasn't the case. I really liked how the ideas are explained simply and there are also pragmatic approaches to find the right businesses to invest in (note that the book talks about investing in a business and not a stock).

I highly recommend it.

Warren Buffett es un genio, tiene una claridad increíble y un proceso estructurado. El libro es repetitivo, pero lo advierten desde el comienzo, es interesante aunque a veces sea lento.

Es una guía perfecta y corta.

Yesterday, I completed the book: “Buffettology” (1997©) written by Mary Buffett and David Clark. This is the book I thought “The Snowball” was going to be, but wasn’t. This is the book that tells you how you too can make a lot of money (with certain qualifications). All of the “tricks of the trade” – what to look for and why, and how to figure out if a company is going to make you money or not (and how soon it will do it). It’s all here in this little gem of a book. I highly recommend it!!
The main author – Mary Buffett is the former spouse of one of Warren Buffett’s sons. Nothing like making a little bread off the ex-father-in-law’s name…

Oh, about those qualifications… It helps to start off with about 15 years worth of the average persons gross pay in the bank to start investing. You also have to be quite obsessed with making money. You also have to be able to live off of a fraction of your earnings until you start to really roll in the dosh – that means patience and a willingness to forego instant gratification. But once you do these things, you can be well on your way to becoming quite wealthy – in 30 or so years. Actually, if you follow the guidelines laid out in this book, I’d wager you’d be quite well off in just 10 or 15 years.

Anyway, as I said, this is an excellent read for anyone interested in working their way into a comfortable lifestyle and I highly recommend the book. Forgive my snarkiness. It’s actually a very good book with lots of great tips for investing and clear explanations for how to understand how you really make money work for you.

This book is basically for indivduals with a background in investing/equity research. If you are looking for a groundbreaking strategy sadly there is none out there that can make you super rich. This book mainly explains the basic fundamentals that Buffet used in investing.

If you are young, have a good background in investments and have a source of income/wealth then you can use these fundamental combined with you existing skills to follow these strategies and be reasonable successful in terms of generating superior returns.

The biggest takeaway is that you need to invest a lot of time and effort in finding companies that have certain favorable economics working to it's advantage, pay a reasonable price and stay patient. To do all of this you need to be well versed with analyzing industries, analyzing financial statements and above you need to know how to value companies.

All in all a great read for someone looking for direction in investing.

There's nothing groundbreaking here. It works more as a primer for economics at large and the stock market in particular. The later half of the book is full of mathematical equations, designed to help wannabe Buffetts in making sound stock-buying calls. For the casual reader though, its the first half which is interesting as it provides an insight into the mind of the world's most successful investor.

It is great book with simple but difficult steps to follow to decide which company to invest in. Patient is a key element for value investment and a proper research can help you out to entertain the waiting. The book might be a bit old but the principles are up to date for investment. Can try with the list of companies that Buffett was/is interested in to practice how to value a company while you wait.

The information was severely outdated and the author was extremely redundant. She also presented it as “leaking secrets now that she’s divorced from Warren’s son”. I honestly didn’t learn anything new about investing that I didn’t already know. I’d pass and go for a more current book if I could go back. I gave a generous 3 stars because I enjoyed hearing the stories of Warren when he was younger.

A must read for anyone who is looking for a information and knowledge on how to invest, properly, in individual stocks.

This book puts you inside Warren Buffet's brain and how he analyses businesses and stocks.

Warren is the pinnacle of value and quality investment strategies, and there's still so much to learn from him as an investor.

I recommend it to any investor.

Neither good nor bad. The ideas are at the level of basic Econ 101. A beginner investor can benefit from some of material but anyone who has bought or sold stocks for a while already knows most of this book.

Very average. Looks like the author wants to show that she really knows Warren buffett. And she does it by repeating his name a at least 5 times on every page! If that wasn’t enough she keeps on telling the same examples with different sums of money. Just to say ‘see that’s a lot of money I am talking about’!! She almost treats the reader like a child. I found some phrases quite funny like at the end of a very simple concept Ms Buffett said ‘now go back and read that again’!! I mean seriously!!

Buffet hasn’t recommended this book anywhere but I just thought it might give something new. I am not in finance but those who are will definitely find it a bit annoying.

If you have read Graham no need to even look at it.

The thing about reading an investing-oriented book 15 years after it was published is that you can judge the projections and assumptions made in the book. Buffetology was generally a decent book, but many of the suggestions and insights are overly simplistic and could have led to disasterous results over the last decade (suggesting investments in Bear Stearns and Freddie Mac). Additionally, I did not particularly care for the informal, peppy tone of the authors. I have the distinct feeling that the author got this book deal solely due to her former relationship to Mr. Buffet; the book sold well solely due to her continued use of her ex-husband's last name. I did find her methods of qualitatively evaluating the opportunity and her focus on the need for patience in investing quite good. You may not learn much of anything by reading this unless you have little knowledge of business, but it is somewhat entertaining.

Saw on multiple articles and heard on my podcast that this book was one of the books you should read if you're an investor. I really enjoyed the first part of the book. I'm a real warren buffet fan, I mean who in finance isn't, and reading about his personal life and how he brought that over into his family was really fun to read. Now as to the second part, "Advanced Buffetology" the style of writing was really boring. Being in finance, mostly everything interest me but this part was really repetitive. The chapters, even thought already short, could have been shortened or even combined. I know this book was written in 1999 so for someone who read it in 2017, it's really outdated. Ex: like how to receive finically statements spoiler : everything is on the Internet/websites now. Outdated portion really took away from the book in my personal opinion. I gave it four stars since I can't give it 3.5.

There are plenty of books about Warren Buffett available at any bookstore or library. What makes this one unique is that it is not written from the perspective of Warren Buffett's cult following. After her divorce with Warren Buffett's son, Mary Buffett capitalized on a rare opportunity to publish insider information about one of the richest people in the world and his investment strategies. Rather than quote Warren Buffett's shareholder letters to death like most authors, Mary sticks to the details of Warren's investments, how he made each choice and how it worked out. She provides a lot of quantitative data that is useful for reverse-engineering Warren Buffett's portfolio. Information from this book definitely helped me refine a few aspects of my investing philosophy and my screening process. Mary is concise and unemotional, making this a quick and productive read.

Intro to discounted price of future earnings. I've applied the formulas to several large cap stocks in a fantasy portfolio. My performance currently matches the S&P 500 pretty closely (including brokerage fees) but a lot of my success is due to one speculative stock that I could barely justify using the recommendations in this book.

Earnings are only part of the picture in stock valuation. There are million other Warren wannabes out there that also have a big say in what a stock is worth.

If you are curious as to how the world's richest man did it, READ this book.

For all stock investors out there who are wondering how after giving away almost all of his wealth a few years back, Warren managed to overtake Bill gates as the man with the most wealth in this planet. That's quite a feat if you ask me! Well, don't ask me. Just read and learn my friend.

If you are interested in investing in stocks, read this book. It teaches you some very important concepts that you will want to know before you put one single dollar down on any stock.

Well worth the read.

Obviously, this is not a novel, and likely not at all interested if not investing in stocks.
