Why Natural Ratios May Not Constrain Emotional Markets

Desmond is skeptical of methods such as Fibonacci analysis when they transfer fixed relationships from the physical world into financial markets. His objection is that markets are governed by variable human emotion, whose range is not necessarily bounded by a natural geometric ratio.

  • Fibonacci ratios originate in observable physical patterns
  • Markets are driven by buyers' and sellers' emotions
  • Human enthusiasm and fear can reach unusual extremes
  • Physical regularity does not automatically imply predictive market limits

“what controls the stock market is not the physical world. It's the emotional world.”

Paul Desmond · 48:56

“the range of human emotion has almost no limit to it.”

Desmond Says For-Profit Exchanges Sacrificed Market Ethics

Desmond argues that converting the New York Stock Exchange from an institution into a profit-making corporation had damaging consequences. He links that change to high-frequency trading, the loss of specialist responsibility, paid speed advantages, and a diminished commitment to orderly and ethical markets.

  • The exchange once operated more like a market institution or utility
  • Profit incentives encouraged the sale of speed and data advantages
  • Human specialists had responsibility for orderly markets
  • Front-running-like behavior became normalized through market structure
  • Desmond believes ethics should outrank exchange profitability

“the biggest thing in my mind that's occurred in in in my career is that the New York Stock Exchange used to be an institution…”

Paul Desmond · 1:50:11

“Ethics was paramount paramount.”

Why Markets Turn Before the Fundamentals Do

Desmond argues that reported earnings and economic data describe current or past conditions, while prices reflect expectations about the future. Markets can therefore decline while earnings remain positive or rise while economic news remains terrible.

  • Investors trade on expected future conditions
  • Fundamental reports arrive after expectations have changed
  • Prices can weaken before earnings deteriorate
  • Major bottoms can occur amid extremely negative economic news

“People buy and sell stocks not because of what they know today, but what they think is going to happen in the future.”

Paul Desmond · 10:06

“the major turning points in the stock market occur because of psychology, not because of evidence provided by fund the fundamental school.”

How ETFs Brought Fund Investing Into the Modern World

Desmond identifies ETFs as one of the most important market innovations of his career. Unlike mutual funds priced only after the close, ETFs trade continuously, offer low-cost access, and work for both individual and institutional investors.

  • Traditional mutual-fund pricing reflects old operational constraints
  • ETFs provide intraday pricing and liquidity
  • The structure serves small and large investors
  • Portfolio changes can occur internally while investors hold one security

“Instead of being priced once a day, we're going to be priced day long, TI tick all day long”

Paul Desmond · 1:47:06

“it's the perfect investment for all types of investors.”

How a Library Visit Led to Paul Desmond's 50-Year Career

After taking over his ill father's portfolio, Desmond studied investing at the Miami public library and discovered Lowry's supply-and-demand research. He drove to the address on a Saturday, mistook founder L. M. Lowry for a gardener, talked with him for hours, and began working there less than ten days later.

  • Desmond began studying markets to manage his father's portfolio
  • Lowry's research matched his belief in supply and demand
  • The firm's address led him to Lowry's private Miami estate
  • He sought an education rather than a conventional job
  • The encounter began a career lasting more than fifty years

“I was looking for education.”

“I'm willing to work for nothing.”

Joe Granville's Spectacular Ego—and the Calls He Missed

Desmond recalls market personality Joe Granville as talented, theatrical, and extraordinarily self-confident. Granville explained missed market turns by claiming that other pursuits had made him one of the world's leading bridge players, sailors, or specialists, illustrating how reputation and ego can overwhelm disciplined analysis.

  • Granville developed the on-balance-volume concept
  • His presentation style attracted crowds and moved markets
  • He rationalized missed calls through extravagant stories
  • Desmond distinguishes sincere self-belief from deliberate fraud
  • A strong track record can foster dangerous overconfidence

“they are the most egotistical human beings I've ever met in my life.”

Paul Desmond · 1:26:37

“he ate his own cooking. He believed in himself.”

Desmond's Career Advice: Study Supply and Demand, Then Find a Mentor

For graduates entering finance, Desmond recommends learning supply-and-demand analysis and seeking an experienced practitioner willing to teach. Mentorship only creates an advantage when the learner works hard, listens carefully, applies the advice, and converts it into direct experience.

  • Study supply and demand as a foundational discipline
  • Actively seek a capable mentor
  • Expect long hours and substantial listening
  • Apply advice rather than merely collecting it
  • Experience turns instruction into durable skill

“search out a mentor.”

Paul Desmond · 1:53:26

“finding a mentor is is we'll put you, We'll put you miles and miles ahead of the competition.”

Why Lowry's Built an Operating Companies Only Index

Desmond explains that the New York Stock Exchange gradually accumulated bond-like securities, funds, REITs, and preferred shares alongside domestic common stocks. Lowry's created an operating-companies-only universe to remove those distortions and measure how actual domestic common stocks were behaving.

  • The NYSE is no longer composed primarily of common stocks alone
  • Bond-like securities can distort market breadth
  • Preferred shares may behave more like bonds than equities
  • A clean universe improves advance-decline and volume analysis

“the only thing that's in that group is is is domestic common stocks.”

Paul Desmond · 32:34

“investors wanted to know is how are common stocks domestic common stocks moving on the exchange.”

Technical Analysis Is Really Supply-and-Demand Analysis

Desmond considers the label "technical analysis" too broad and imprecise. He describes charts, prices, and volume as records of the continuing auction between buyers and sellers, with price direction determined by which side is more anxious to transact.

  • Every trade has both a buyer and a seller
  • Price direction reveals which side is more urgent
  • Charts visualize the daily contest between supply and demand
  • Desmond prefers the term supply-and-demand analysis

“we should not use the word technical. We should be using the word supply and demand.”

Paul Desmond · 37:15

“when you're looking at a chart, what you're really seeing is the daily battle of demand versus supply.”

Paul Desmond's Two Timeless Money Books

Desmond recommends The Richest Man in Babylon for enduring lessons about becoming financially successful. He also highlights Reminiscences of a Stock Operator as a timeless account whose market lessons still feel contemporary when company names are changed.

  • The Richest Man in Babylon presents financial lessons through a short narrative
  • Desmond regards its principles as broadly applicable
  • Reminiscences of a Stock Operator teaches recurring investor lessons
  • Human market behavior changes less than market technology

“There's a book called The Richest Man in Babel.”

Paul Desmond · 1:35:29

“It tells you a lot of the lessons you need to learn in order to be a successful investor.”
