Book Notes: Benjamin Graham

The Intelligent Investor (1973) + Security Analysis (1934), by Benjamin Graham

Benjamin GrahamTo invest intelligently in securities one should be forearmed with an adequate knowledge of how the various types of bonds and stocks have actually behaved under varying conditions—some of which, at least, one is likely to meet again in one’s own experience.

An investment operation is one which, upon thorough analysis promises safety of principle and an adequate return. Operations not meeting these requirements are speculative. An investment operation is one that can be justified on both qualitative and quantitative grounds.

We speak of an investment operation rather than an issue or a purchase, for several reasons. An investment might be justified in a group of issues, which would not be sufficiently safe if made in any one of them singly. In our view it is also proper to consider as investment operations certain types of arbitrage and hedging commitments which involve the sale of one security against the purchase of another. The safety sought in investment is not absolute or complete; the word means, rather, protection against loss under all normal or reasonably likely conditions or variations. A safe stock is one which holds every prospect of being worth the price paid except under quite unlikely contingencies.

Outright speculation is neither illegal, immoral, nor (for most people) fattening to the pocketbook. There is intelligent speculation as there is intelligent investing. But there are many ways in which speculation may be unintelligent. Of these the foremost are: (1) speculating when you think you are investing; (2) speculating seriously instead of as a pastime, when you lack proper knowledge and skill for it; and (3) risking more money in speculation than you can afford to lose.

The defensive (or passive) investor will place his chief emphasis on the avoidance of serious mistakes or losses. His second aim will be freedom from effort, annoyance, and the need for making frequent decisions. The determining trait of the enterprising (or active, aggressive) investor is his willingness to devote time and care to the selection of securities that are both sound and more attractive than average.

Obvious prospects for physical growth in a business do not translate into obvious profits for investors. The future of security prices is never predictable.

In his endeavor to select the most promising stocks wither for the near term or the longer future, the investor faces obstacles of two kinds—the first stemming from human fallibility and the second from the nature of his competition. He may be wrong in his estimate of the future; or even if he is right, the current market price may already fully reflect what he is anticipating. In the area of near-term selectivity, the current year’s results of the company are generally common property on Wall Street; the next year’s results, to the extent they are predictable, are already being carefully considered. Hence the investor who selects issues chiefly on the basis of this year’s superior results, or on what he is told he may expect for next year, is likely to find that others have done the same thing for the same reason. To enjoy a reasonable chance for continued better than average results, the investor must follow policies which are (1) inherently sound and promising, and (2) not popular on Wall Street.

Book Notes: Innovation and Entrepreneurship

As with my other book notes, some passages are direct quotes and others are my own paraphrasing/summaries. Any footnotes or [brackets] are my personal comments.

Innovation & Entrepreneurship (1985), by Peter Drucker

Innovation and Entrepreneurship“The entrepreneur,” said the French economist J. B. Say around 1800, “shifts economic resources out of an area of lower and into an area of higher productivity and greater yield.”

All new small businesses have many factors in common. But to be entrepreneurial, an enterprise has to have special characteristics over and above being new and small. Indeed, entrepreneurs are a minority among new businesses. They create something new, something different; they change or transmute values. An enterprise also does not need to be small and new to be an entrepreneur. Indeed, entrepreneurship is being practiced by large and often old enterprises.

The entrepreneur upsets and disorganizes. As Joseph Schumpeter formulated it, his task is “creative destruction.” They see change as the norm and as healthy. Usually, they do not bring about the change themselves. But—and this defines entrepreneurship—the entrepreneur always searches for change, responds to it, and exploits it as an opportunity.

When shifting resources to a more productive area, there is a risk the entrepreneur may not succeed. But if they are even moderately successful, the returns should be more than adequate to offset whatever risk there might be. One should thus expect entrepreneurship to be considerably less risky than optimization. Indeed, nothing could be as risky as optimizing resources in areas where the proper and profitable course is innovation, that is, where the opportunities for innovation already exist. Theoretically, entrepreneurship should be the least risky rather than the most risky course. [There are “hidden” risks of not being an entrepreneur.]

“Innovation,” then, is an economic or social rather than a technical term. It can be defined the way Say defined it, as changing the yield of resources. Or, as modern economists would tend to do, it can be defined in demand terms rather than in supply terms: changing the value and satisfaction obtained from resources by the consumer.

How to separate luck and skill

These are some of my notes from the book “The Success Equation” by Michael Mauboussin. This book was spotted on Warren Buffett’s desk in this tour of his office. There’s lots more interesting stuff in the book, but these notes in particular answer the question “How do you separate luck and skill?” We’ll start off with some definitions:

Luck is a chance occurrence that affects a person or a group (e.g., a sports team or a company). Luck can be good or bad. Furthermore, if it is reasonable to assume that another outcome was possible, then a certain amount of luck is involved. In this sense, luck is out of one’s control and unpredictable. Randomness and luck are related, but there is a useful distinction between the two. You can think of randomness as operating at the level of a system and luck operating at the level of the individual. Luck is a residual: it’s what is left over after you’ve subtracted skill from an outcome.

The definition of skill depends on how much luck there is in the activity. In activities allowing little luck, you acquire skill through practice of physical or cognitive tasks. In activities incorporating a large dose of luck, skill is best defined as a process of making decisions. Here, a good process will have a good outcome but only over time. Patience, persistence, and resilience are all elements of skill.

Separating luck and skill

Luck-Skill Continuum
At the heart of making this distinction lays the issue of feedback. On the skill side, feedback is clear and accurate, because there is a close relationship between cause and effect. Feedback on the luck side is often misleading because cause and effect are poorly correlated in the short run.

In most cases, characterizing what’s going on at the extremes is not too hard. As an example, you can’t predict the outcome of a specific fair coin toss or payoff from a slot machine. They are entirely dependent on chance. On the other hand, the fastest swimmer will almost always win the race. The outcome is determined by skill, with luck playing only a vanishingly small role.

Book Notes: The Visible Hand

The Visible Hand: The Managerial Revolution in American Business was written by Alfred Chandler and released in 1977. It’s a great history and study on business and why it exists the way it does today. For some books I read, I transcribe and summarize my highlights/notes in order to better learn the material and for future reference. Below you’ll find my (very long) summary of The Visible Hand. Some passages are direct quotes and others are my own paraphrasing/summaries. So if you’re interested in this sort of topic, send this baby to Instapaper, plop down on the couch, and enjoy.

The Visible Hand

Modern business enterprise is easily defined, having two specific characteristics: (1) it contains many distinct operating units and (2) it is managed by a hierarchy of salaried executives. Each unit has its own administrative office, set of books and accounts. Each could theoretically operate as an independent business enterprise. Such enterprises did not exist in the U.S. in 1840. By World War I this type of firm had become the dominant business institution. It was the institutional response to the rapid pace of technological innovation and increasing consumer demand.

This study is a history, moving chronologically. Before entering the historical experience, here is a list of general propositions to make more precise the primary concerns of the study:

The initial appearance of modern business enterprise:

  1. Modern multiunit business enterprise replaced small traditional enterprise when administrative coordination permitted greater productivity, lower costs, and higher profits than coordination by marker mechanisms. [This was due to both corporate efficiency and economies of scale.]
  2. The advantages of internalizing the activities of many business units within a single enterprise could not be realized until a managerial hierarchy had been created. An enterprise without such managers remains little more than a federation of autonomous offices.
  3. Modern business enterprise appeared for the first time in history when the volume of economic activities reached a level that made administrative coordination more efficient and more profitable than market coordination. It came with new technology and expanding markets.

Growth of the modern business enterprise:

  1. The hierarchy itself became a source of permanence, power, and continued growth.
  2. The careers of the salaried managers who directed these hierarchies became increasingly technical and professional. Training became longer and more formalized.
  3. The management of the enterprise became separated from its ownership. Stockholders didn’t have the influence, knowledge, experience, or commitment to take part in the high command.
  4. Career managers preferred policies that favored the long-term stability and growth of their enterprises to those that maximized current profits. For salaried managers the continuing existence of their enterprises was essential to their lifetime careers.
  5. As the large enterprises grew and dominated major sectors of the economy, they altered the basic structure of these sectors and of the economy as a whole.

My favorite books on business, management, investing and design

Out of the many books I’ve read in different subjects, below is a list of some of my favorites with some brief commentary for some of them. There are a few other “Mental Model” categories (psychology, history, economics, ecology, etc.) that I left out — hopefull they’ll be the subject of another post.

Business theory

  • The Origin and Evolution of New Businesses, Amar Bhide — extensive study of startups of all kinds, how they grow, what makes them successful (this is not a “help” book it is mainly observational)
  • Innovation & Entrepreneurship, Peter Drucker — how companies should systematically innovate — lots of good startup/innovation strategies (it’s not random)
  • The Innovator’s Dilemma, Clayton Christensen — every businessperson or investor needs to read this (and the one below) — every industry’s value chain is disrupted at some point
  • The Innovator’s Solution, Clayton Christensen — expands on “Dilemma” with better explanations and examples — I think the “jobs to be done” concept is one of the most important in business
  • Competition Demystified, Greenwald + Kahn — how businesses capture value by building a moat, and what strategies to use if you have or don’t have one
  • The Halo Effect, Phil Rosonzweig — the anti-business-book — but still has great insights on how businesses work and how best to run them
  • Built to Last, Jim Collins — read this with The Halo Effect in mind — lots of good advice & stories (I like this much better than “Good to Great”)
  • The Strategy Paradox, Michael Raynor — dense at times but a great theory on why strategy is so hard
  • Hidden Champions, Hermann Simon

The McDonald’s Success Story

I am currently in the process of researching and writing a long article on the restaurant industry, or more specifically Steak n Shake, McDonald’s, and In-N-Out Burger. I should have it finished in a few weeks or so. In the mean time, please enjoy the following excerpt of the article on McDonald’s:

McDonald's (courtesy of

As Ray Kroc sat in his car, he watched a miracle unfold. The parking lot was full, the lines were long, and customers were leaving with an arm-full of food and a smile on their face. Kroc stopped a few to see what was going on: “You’ll get the best hamburger you ever ate for fifteen cents. And you don’t have to wait and mess around tipping waitresses.” He had travelled the country selling milkshake machines, visiting countless restaurants of all types. But he had never seen a merchandising operation like this. It was 1954; fourteen years after the McDonald brothers opened their small burger drive-in in the town of San Bernardino, California.
