Learn the why. Not just the what.
Investing fundamentals, market logic, and the discipline behind good decisions.
Why Leverage Amplifies Regret More Than It Amplifies Returns
Leverage is mathematically symmetric: it amplifies gains and losses in equal proportion. In the psychological experience of the investor, however, leverage is profoundly asymmetric—the losses it amplifies produce substantially more regret, anxiety, and behavioural disruption than the gains it amplifies produce satisfaction. This asymmetry makes leverage far more damaging to the long-run investor than its mathematical properties alone would suggest.
Why Knowing Why You're Investing Changes Everything
The question that most investment frameworks never ask—why are you investing?—is the question whose answer determines the appropriate response to almost every other investment question. The investor who knows why she is investing makes better decisions at every stage of the investment process, not because she has more information but because she has a framework within which information becomes useful.
Why Time in the Market Beats Timing the Market
The aphorism that time in the market beats timing the market is among the most repeated in personal finance—and among the most systematically ignored in practice. Its truth is supported by overwhelming evidence. Its neglect is explained by the psychology of an investor who finds patience far harder than action.
Why Simple, Boring Investing Usually Wins
The most effective investment strategy available to most individual investors is also the most boring: a diversified portfolio of low-cost index funds, held for decades, with minimal interference. This strategy wins not because it is clever but because it avoids the many ways in which cleverness destroys returns.
Why Everyone Bought Crypto at the Top
Every speculative bubble in financial history has had the same structural feature: the peak of participation coincides with the peak of price. The investors who drove prices to their highest levels were not early adopters—they were late entrants who committed capital at precisely the worst moment.
The Investor Who Panicked and Sold at the Bottom
Every major market decline produces the same pattern. As prices fall, a process begins that has little to do with fundamental economic reality and everything to do with the psychology of collective fear.
Why Smart People Make Dumb Investment Mistakes
Intelligence and investment performance have a weaker relationship than most people suppose, and in some respects an inverse one. Not only do highly intelligent people make the same psychological errors as everyone else, but they often make them with greater conviction and more elaborate justification.
Understanding MACD: The Logic Behind the Lines
MACD is one of the most widely used momentum tools in technical analysis, yet most people read it without understanding what it actually measures. Strip away the mystique and it is simply a way of watching the relationship between two moving averages change over time.
Long-Term Capital Management 1998: When Genius Failed
The 1998 collapse of Long-Term Capital Management, run by Nobel Prize-winning economists, remains one of the most-studied case studies in financial risk. Understanding what happened provides essential lessons.
Recency Bias: Yesterday's Weather, Tomorrow's Forecast
The systematic tendency to overweight recent experience in decisions about the future is one of the most consistent behavioral patterns in investing. Understanding the mechanism is essential to avoiding its costs.
Systematic vs Discretionary: Two Roads Up
Investment approaches divide broadly between systematic rules-based strategies and discretionary judgment-based approaches. Each has specific advantages and specific limitations worth understanding.
Short Interest, Squeezes, and Positioning Extremes
Extreme short positioning creates specific market dynamics that can produce dramatic price moves. Understanding the mechanics is essential to reading modern market events.
Chart Time-Frames: How to Layer Them
Reading the same market on multiple time-frames simultaneously produces richer analytical context than any single time-frame provides. Understanding how to layer time-frames is one of the more useful chart-reading disciplines.
Japan 1989: Lessons from a 30-Year Bear
The Nikkei 225 peaked at 38,957 in December 1989 and did not surpass that level until 2024 — a 34-year period. Understanding the specific dynamics is one of the most instructive lessons in modern market history.
The Illusion of Control
The systematic tendency to overestimate one's ability to influence outcomes is one of the most-consistent patterns in investor behavior. Understanding the mechanism helps calibrate confidence in specific investment analysis.
Factor Investing: What 'Smart Beta' Actually Is
Factor investing systematically captures the specific patterns academic finance has identified in cross-sectional returns. Understanding what factors work and why is essential to any coherent view of the approach.
Volume-Weighted Average Price (VWAP) as a Yardstick
VWAP provides a specific measure that institutional traders use to evaluate execution quality. Understanding what VWAP represents and how it is used helps read markets from the specific institutional perspective.
ATR and the Practical Meaning of Volatility
The Average True Range indicator quantifies volatility in a specific way that supports practical decision-making about position sizing and risk management. Understanding what it measures is essential to using it well.
SVB and the 2023 Regional Bank Crisis
The March 2023 failure of Silicon Valley Bank and the associated regional banking stress was one of the most significant banking events since 2008. Understanding what happened is essential to reading modern financial stress dynamics.
Framing Effects: How the Same Number Feels Different
The way information is presented shapes how it is evaluated, independent of the underlying facts. Framing effects operate constantly in investment decisions and produce systematically different responses to identical information.
Contrarian Investing: When the Crowd Is Wrong
Contrarian investing — taking positions against prevailing market opinion — is one of the most-discussed approaches in retail investing. Understanding when it works and when it fails is essential to actually applying it effectively.
Fat Tails: Why Normal Distributions Undersell Risk
Financial return distributions have more extreme outcomes than normal distributions would predict. Understanding the mechanism explains why standard risk models fail during exactly the periods when they matter most.
Market Breadth: The Health Check Beneath the Index
Index-level prices describe what the largest constituents are doing. Breadth indicators describe what the broader market is actually doing beneath the surface — often a very different picture.
The 2022 Rate Shock: 60/40's Worst Year
The traditional 60/40 stock/bond portfolio produced one of its worst years in modern history in 2022. Understanding the specific mechanism reveals important lessons about the assumptions embedded in the framework.
