Howard Marks


»We have two classes of forecasters: Those who don’t know — and those who don’t know they don’t know.« – John Kenneth Galbraith

»Since extrapolation is appropriate [reg. macro forecasts] most of the time, most of the people’s forecasts are roughly correct. But becasue they’re already reflected in security prices, most extrapolation aren’t a source of above average returns. The forecasts that produce great profits are the ones that presciently foresee radical deviations from the past. But that kind of forecast is, firstly, very hard to make and, secondly, rarely right. Thus most forecasts of deviation from trend also aren’t a source of above average returns.« – Howards Marks

Howards Marks, in uncertainty

Risk Aversion

»Our initial analysis of any company always considers the real risks of investing. This is the risk of permanent capital loss. We look hard at balance sheets and stay far away from highly leveraged businesses. This is especially true during periods of deep economic uncertainty like the one we are in now.« – Tweedy, Browne

tweedy.com, in Q1 2020 letter

»You can’t have intelligent investing in the absence of quantification of value and insistence on an attractive purchase price.« – Howard Marks

Howard Marks, Mastering the market cycle

»An engineer can have a successful career knowing nothing other than engineering. Same for a chemist, meteorologist, or radiologist. Business and investing don’t work like that. They’re a little math, a little accounting, a little sociology, a little psychology, a few parts marketing, law, politics, game theory, history, statistics, biology, and public relations. That doesn’t make them harder than other fields; just more uncertain, prone to chance, and with fewer experts.« – Morgan Housel in A Few Things I’m Pretty Sure About

Morgan Housel (collaborative)

»Value investing is a lot more than just buying statistically cheap companies that trade at low P/Es. It is a philosophy, a framework. It is about buying companies that are undervalued, and this undervaluation may not be staring you in the face. It is also about availing yourself of positive optionality (significant positive outcomes that are hard to evaluate today) – and most importantly, not paying for them.« – Vitaliy Katsenelson

Vitaliy Katsenelson, kidnapped email-series, part 5

»Proper valuations are far more art than science. DCF valuations – especially of something growing near or above the discount rate are famously sensitive to assumptions. The right comparison is to the Hubble Telescope: move direction a fraction of a degree and you wind up in another galaxy.« – John Hempton

»All of the information is in the past, but all of the value is in the future.« – Bill Miller

Bill Miller, taken from Pat Dorsey

Bruce Greenwald (source)

Bets and odds

»What good poker players and good decision-makershave in common is their comfort with hte world being an uncertain and unpredictable place. They understand that they can almost never know exactly how something will turn out. They embrace that uncertainty and, instead of focusing on being sure, they try to figure out how unsure they are, making their best guess at the chances that differnet outcomes will occur.« – Howard Marks

Howard Marks, quoting Annie Duke (Thinking in Bets) in his memo uncertainty

»I’ve learned many things from George Soros, but perhaps the most significant is that it’s not whether you’re right or wrong that’s important, but how much money you make when you’re right and how much you lose when you’re wrong. The few times that Soros has ever criticized me was when I was really right on a market and didn’t maximize the opportunity.« – Stanley Druckenmiller

Stanley Druckenmiller

Vitaliy Katsenelson, contrarianedge.com

»Mr. Market is there to serve you, not to guide you. It is his pocketbook, not his wisdom that you will find useful. If he shows up some day in a particularly foolish mood, you are free to either ignore him or to take advantage of him, but it will be disastrous if you fall under his influence. Indeed, if you aren’t certain that you understand and can value your business far better than Mr. Market, you don’t belong in the game.« – Warren Buffett

Warren Buffett, 1987 letter to Berkshire Hathaway shareholders

»If you’re not willing to react with equanimity to a market price decline of 50% two or three times a century, you’re not fit to be a common shareholder and you deserve the mediocre result you’re going to get.« – Charlie Munger

Charlie Munger (Interview with BBC)

»The Bottom is the day before the recovery begins. Thus it’s absolutly impossible to know when the bottom has been reached … ever. Oaktree explicitly rejects the notion of waiting for the bottom; we buy when we can access value cheap.« – Howard Marks

Howard Marks (Letter to Investors, March 2020)

»Investment performance is what happens when a set of developments – geopolitical, macroeconomic, company-level, technical and psychological – collide with an extant portfolio. Many futures are possible […] but only one future occurs.« – Howard Marks

»The stock market is filled with individuals who know the price of everything, but the value of nothing.« – Phillip Fisher

Howard Marks (you bet)

»For most investors if a stock starts behaving in a way that is different from what they think it ought to be doing—say, it falls 15%—they will probably sell. In our case, when a stock drops and we believe in the fundamentals, the case for future returns goes up.« – Bill Miller

Bill Miller, CIO of Miller Value Partners (link)

Peter Lynch

»Everyone has a plan until they get punched in the mouth.« – Mike Tyson

Mike Tyson

»Earnings don’t move the overall market; it’s the Federal Reserve Board… focus on the central banks and focus on the movement of liquidity… most people in the market are looking for earnings and conventional measures. It’s liquidity that moves markets.« – Stanley Druckenmiller

Other Topics

Below I list some quotes belonging to topics besides investing, some of them much more important to mankind then optimizing returns and our investment strategies

»… All we have to decide is what to do with the time that is given to us.«
– J.R.R. Tolkien

J.R.R. Tolkien – The Lord of the Rings

»Not everything that counts can be counted … and not everything that’s counted truly counts.« – Albert Einstein

Albert Einstein

»It’s 24 hours before your birth, and a genie appears to you. He tells you that you can set the rules for the world you’re about to enter — economic, social, political — the whole enchilada. Sounds great, right? What’s the catch?
Before you enter the world, you will pick one ball from a barrel of 6.8 billion (the number of people on the planet). That ball will determine your gender, race, nationality, natural abilities, and health — whether you are born rich or poor, sick or able-bodied, brilliant or below average, American or Zimbabwean.
This is what I call the ovarian lottery. You’re going to get one ball out of there, and that is the most important thing that’s ever going to happen to you in your life. That’s a good perspective to have when setting the rules for our world.
We should be designing a society that doesn’t leave behind someone who accidentally got the wrong ball and is not well-wired for this particular system.«
– Warren Buffett
