A Lesson About Compound Returns From Warren Buffett

By Motley Fool Staff Markets Fool.com

The law of compounding returns isn't a secret, but it's nevertheless a difficult subject to get one's head around. None other than Albert Einstein once referred to it as the Eighth Wonder of the World.

Gaby Lapera: Speaking of someone who has had a very long life, Warren Buffett. Exciting news from Omaha this week. He released his long-anticipated investor letter that he does every year. That is something that's ... I don't know how to describe it. It's like the Great American novel of American investing that gets written every year. If you look back at past ones, it's just this beautiful collection of investing wisdom from one of the best investors ever.

John Maxfield:If not the best.

Lapera:I know you were really excited about this, Maxfield.

Maxfield:I was.I think that's a great way that you framed it. It's not just that it's, maybe, the most valuable document that has ever been written about investing, which, I think it is, but it's a living document. He's adding to it each year. So we can not only see what he says each year, but we can see how his thought process evolved. For an individual investor, you just couldn't have a more valuable document to study than his letters.

Lapera:That's so true. For all you millennials out there, it's like Harry Potter for investing, except it doesn't end. At least I make myself laugh, and you, which is good. So one of the things that characterizes this letter is that the first page always has all the returns thatBerkshirehas had since 1965, when Buffett took over Berkshire. Do you want to expound a little bit on what's going on there?

Maxfield:Let me start out with a slightly different thing. One of the things that when the letter comes out, somebody like me reads immediately. Other people in the media industry do the same thing. What you're doing is looking for those pithy quotes, or what he has to say about stuff like the American economy or stuff like that. But I think one of the things that's really important, it's not only that investors should read his letter -- I honestly think that investors should always read his letters -- but it's also about how you read them. You don't want to just fall into that habit of going through and superficially picking out the favorite pithy quote that he had to say, or the five awesomest quotes that he had to say, or what he had to say about politics or the American economy. You really want to sit down and switch your thought process from that instinctual system one, which is how they refer to it in behavioral finance, into more of that calculated, slower thought process, where you're actually thinking and analyzing it. When you think about Warren Buffett, I think it's really important that while we can all sit around and say, "This guy is the most successful investor," I mean, as far as I know, and I've read quite a bit about investing, he's the most successful investor over such a long stretch of time of all time. But that doesn't mean that you should suspend your critical thought process even when reading Warren Buffett's letters.

Lapera:Not at all. I think one of the best things I picked up from college, and thathelped me get successfully through grad school, was marking up every single thing that I read. I know this must drive librarians crazy, and I'm so sorry about this -- I only do this to books that I actually own, but I take a pen or pencil and I mark every page. So every time that someone says something interesting or something I want to fact-check later, I circle it, I have my own little set of symbols and notations for what I think is actually going on, and at the end of each chapter, I like to give a little summary of the most important points. And at the end of the book, I go back and write down what I thought the best things were, or what were things that I disagreed with, and think on them some more.

Maxfield:Yeah. It's funny, when you were explaining that, there are a lot of people who talk about the process of reading, and a lot of really good readers apply a very similar process to that. So, now, let me answer your first question, Gaby. On the very first page of Warren Buffett's letter, it compares the performance of Berkshire Hathaway since 1965, which is the year that he actually took over the company, until today, and it looks at the performance of Berkshire Hathaway, both the growth and book value per share, the growth in its market value of its actual shares on the exchanges, and it compares that to the S&P 500. And what I love about this first page is, the law of compounding returns, one of those things that is so difficult to get your brain around, because it's just a difficult thing to define. Albert Einstein, who I think we can all agree was a pretty smart guy -- right, Gaby? Do you agree that Albert Einstein is smart?

Lapera:Sure, he's OK.

Maxfield:Yeah. He calls that the Eighth Wonder of the World. So Albert Einstein says this is a difficult concept to understand. But the first page on Warren Buffett's letter really drives home, even if you can't understand it, how incredibly powerful compound returns are. Let meput this into perspective. Over that 52-year stretch, Buffett hasaveraged a 20.8% annualized gainon Berkshire Hathaway stock. Now that's anannualized gain. Over that entire period, he's earned nearly a 2 millionpercentage return on his investors money. What that translates into is, a $10,000investment in Berkshire Hathawayin 1965 -- which,if you factor inflationinto the equation,that's basically enough to buy aBMW5 Series,a nice car but nothing ridiculously fancy -- thattransformed that amount of money into $88 million, i.e., generational wealth for most families.

Lapera:That's crazy.

Maxfield:Isn't it? It's justsuch a good example. And the other thing that really drives this point home about thepower of compounding returns --to put that in perspective, whileBuffett has returned to 2 million percentover that time period,the S&P 500 has returned 12,700%.

Lapera:That'salso very impressive.

Maxfield:It is, but it's like a rounding errorwhen you look at it compared to Warren Buffett's returns. So that second point is,even small differences in percentages over an extended stretch of time, when those returns compound, canresult in a huge difference. Let me give you an example from that first page. The per-share change in Berkshire'sbook value per share is anannualized gain of 19%. But the same, like I was saying, themarket value of its actual shares is20.8%. So a1.8% difference. Over that stretch of time period, that transforms that 2 million percentreturn all the way down to 884,000% return. So just, on a yearly basis,even though it's less than a 2% difference,over the stretch of that 52-year time period,you're looking at a 1.1 millionpercentage difference. The point is, compounding returns issomething that you want to grasp onto as an investor andtake advantage of to the greatest extent that you can.
