The forces. Not the headlines.
Analysis and commentary on markets, companies, and the forces that move them.
Building a Personal Investment Policy Statement
A written Investment Policy Statement is one of the most-effective single practices for maintaining discipline through market cycles. Understanding what to include and how to use it is essential.
Cash as a Position, Not a Failure
Holding cash is often viewed as evidence of investment failure or opportunity cost. Understanding cash's specific portfolio role reveals it as a strategic position with specific benefits, not a residual.
Concentration vs Diversification: The Real Trade-Off
The choice between concentrated and diversified portfolios involves specific trade-offs that are commonly misunderstood. Understanding the actual math and the actual practical implications is essential to informed choice.
The Decision Journal: Recording Why, Not What
Maintaining a written record of investment decisions and the reasoning behind them is one of the most-effective single practices for long-term investment improvement. Understanding what to record — and what not to — is essential.
Base Rate Thinking in Investment Decisions
The single most useful analytical shortcut in investment analysis is asking what the base rate for a particular outcome has been historically. Most retail commentary systematically neglects base rates in favour of specific-situation reasoning.
Holding Period: The Under-Discussed Alpha
The single most important predictor of retail investor returns is not stock selection or timing — it is average holding period. Longer holding periods reliably produce better outcomes for reasons that are widely observed but rarely internalised.
Tax-Loss Harvesting: The One Free Lunch
Tax-loss harvesting is the closest thing to a genuine free lunch in retail investing. Understanding the mechanic and its practical limits produces meaningful after-tax return improvements over long horizons.
Core and Satellite Portfolio Construction
A framework for separating a portfolio's stable foundation from its higher-conviction bets, and why the split matters more than the picks.
Rebalancing Cadence: Yearly, Quarterly, or Threshold?
Rebalancing frequency is one of the most under-discussed decisions in portfolio management. The choice between annual, quarterly, and threshold-based approaches has meaningful long-run consequences.
Sequence of Returns Risk Explained
Why the order of investment returns, not just their average, can determine whether a portfolio survives decades of withdrawals or contributions.
Correlation Risk in a Concentrated Portfolio
Twenty stocks in a portfolio may or may not be diversified. The count matters much less than the correlation structure among them, and most retail portfolios have far less effective diversification than their holder assumes.
Drawdown Management: The Emotional Half of Returns
The mathematical return of a strategy tells you what happened. The maximum drawdown tells you whether the investor holding it would have stayed in long enough for the mathematics to matter.
Position Sizing: The Kelly Formula and Its Cautions
The Kelly formula tells you the mathematically optimal fraction of your capital to allocate to a given bet. The catch is that the assumptions almost never hold in real markets — which is why almost every experienced Kelly user runs a fraction of it.
Portfolio Construction: Weights Matter More Than Names
Two investors can hold identical stocks and produce completely different results. Position sizing dominates security selection in almost every real-world portfolio.
Reading Market Turns With Leveraged Relative-Strength Ratios
A conventional relative-strength ratio compares two unrelated instruments. The LRS ratio compares same-source instruments that differ only in leverage — AAPL/TQQQ, TQQQ/QQQ — to read whether the market is rewarding leverage or punishing it.
How We Decide When to Do Nothing
Doing nothing is a decision — often the correct one — but it's rarely made on purpose. We think it deserves to be a real, deliberate choice rather than a default you drift into.
The Difference Between an Opinion and a Recommendation
We have views on markets, and we publish them. We do not tell anyone what to buy or sell. That line is one we draw on purpose.
Position Sizing as Risk Control, Not Conviction
Most people treat position size as a gauge of conviction — how much you believe in something. We treat it instead as a gauge of how much you could afford to lose if you're wrong.
Rebalancing: The Discipline Most People Skip
Rebalancing asks you to sell some of what's been winning and buy more of what's been losing. That's exactly why it works — and exactly why almost nobody actually does it.
What We Actually Mean by “Long-Term”
"Long-term" gets thrown around so loosely that it's nearly stopped meaning anything. When we use the phrase, we mean something specific by it, and the specificity is the whole point.
When Our Own Readings Disagree
Look at a market from more than one angle for long enough, and the angles will start to disagree. What matters is not the disagreement itself but how it gets handled.
Why We Prefer Rules to Forecasts
A forecast demands that you be right about what's coming. A rule only asks that you decide, ahead of time, how you'll react to whatever comes. The second is a far more realistic thing…
