    Quote for the Week

    While the internet boom lasted, nothing seemed able to deflate the bubble. Few internet and dotcom companies were profitable, but investors never seemed to mind. They looked at the number of customers or subscribers as the basis for valuing internet stocks. The name of the game became raising capital, not making profits. Even when fashionable stocks dipped, there was remarkably little effect on the rest of the market. People had learned that it pays to buy the dips and were not weaned from the habit until it ceased to pay…

    Despite its irrational aspects, the internet boom was more than a matter of inflated valuations. The optimism of the financial markets not only changed the “fundamentals” of individual businesses, it had real and profound effects throughout the whole economy. The boom did not only follow from the development of the internet; it accelerated that development and contributed to the speed and extension of technological innovation. The same was true in telecommunications, where the boom also accelerated the spread of new technology. — George Soros (source)

  • Lessons from a 300 Year Old Book on Markets

    May 13, 2026

    The earliest known book describing any stock exchange was written in 1688. Aptly titled, Confusion of Confusions, Joseph de la Vega describes stock and options trading (mostly of Dutch East India Company stock) on the Amsterdam stock market through a conversation between Shareholder, Merchant, and Philosopher.

    The book is a defining example of how little markets have changed in over three centuries. From the early reference to the game and its primary players to the scheming and manipulation to the influential emotions of greed, fear, and panic, the lessons are old, yet still relevant today.

    It starts with a fitting description of stock markets:

    Quote for the Week

    The pendulum of investment psychology is constantly fluctuating between optimism and pessimism, between greed and fear, between credulousness and skepticism, between risk tolerance and risk aversion. It will always swing, and it is the presence of optimism, greed, credulousness, and risk tolerance that makes markets most dangerous…

    One of the first lessons I heard about pendulums and the swing of investor behavior regarded something I was taught in the early 1970s: the three stages of a bull market. These succinctly capture the essence of investor psychology.

    The first stage comes when a few people begin to realize that there will be improvement. The second stage occurs when most people realize that improvement is already taking place. The third stage comes when everyone thinks that things will be getting better forever. Clearly, the first is early; the last is laughably late. One of my favorite adages – perhaps my favorite of all – is that what the wise man does in the beginning, the fool does in the end. So it’s the buyer in the third stage – who buys when optimism is incorporated, under the assumption that things will always get better – who pays the price. — Howard Marks (source)

  • Jelly Beans and the Importance of Independent Thinking

    Have you ever entered a jelly bean contest, where you try to guess the number of jelly beans in a jar? An interesting thing happens when you take the average of all the guesses.

    Jack Treynor did exactly that. He brought a jar of beans (the non-jelly kind) into two classes and asked the students to guess the number of beans inside. So, the students crowded around the jar. They tried to count the beans or estimate the beans per volume or other such things to come up with their best guess. Then they wrote down their guesses and turned them in.

    Treynor found that in both classes the average of the guesses came very close to the actual number of beans. But what really stood out was that the average of the guesses beat all but one or two guesses. In other words, only one or two students actually did better than the average of the whole group.

    This effect is known as the wisdom of crowds, but it requires a key ingredient:

    Quote for the Week

    In the fund industry, the average manager lasts five years, and the average investor owns four funds, so that’s four managers in the first five years, eight managers after ten years, sixteen after twenty years, and fifty-two over the entire sixty-five years. What is the possibility that fifty-two managers, coming and going, cleaning out their portfolios time after time, could with remote conceivability do as well as the index? The return you get from holding the market portfolio over sixty-five years—even a modest return—demonstrates the “miracle of compounding returns,” and the tremendous impact the cost of active management makes is “the tyranny of compounding costs.” The way mathematics works, this tyranny absolutely overwhelms the miracle of compounding returns; to wit, over an investment lifetime the active equity fund investor captures about 20 percent of the return available simply by holding an all-market index fund. — John Bogle (source)

  • When Investment is Most Businesslike

    April 29, 2026

    Samual Curtis Johnson had an idea. This wasn’t new. He had many ideas throughout life. But at age 53, he gave his idea a try. He started a parquet floor business in 1886.

    Within two years, he had a small but thriving flooring business. He also had a customer base that wanted a better way to take care of their new floors. Soap and water ruined the floor finish and shellacs chipped and were a pain to deal with. His customers wanted something better.

    With a little experimentation and a bathtub, Johnson created a floor wax. He gave it away, as an added service, with every new floor sold. What Johnson had done, though he didn’t know it yet, was diversify his business.

    Soon, people he never sold new floors to, wanted to buy his floor wax. A happy accident turned a parquet floor company into a wax company that sold parquet floors. And another idea sprung from that. What if the wax could be used for things other than floors?
