The forces. Not the headlines.
Analysis and commentary on markets, companies, and the forces that move them.
VTI, VOO, and SCHB: The Total-Market Trio Compared
Three ETFs that look almost identical carry small structural differences worth understanding — expense ratio is only the beginning.
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.
Japan: TOPIX Reflation and the End of ZIRP
After two decades of near-zero rates, Japan is normalising monetary policy while corporate reform quietly transforms the equity market. The two shifts explain most of TOPIX's return this decade.
The Fed's Dual Mandate in Practice
Congress gave the Federal Reserve two goals — stable prices and maximum employment. How the Fed weights them in real time explains most of what its policy actually does.
Where the Tape Stands: Mid-August 2026
A structural read of the mid-August market — index levels, breadth, sector heat, volatility, and the yield curve — with no forecasts attached.
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.
What Global Diversification Actually Reduces
Global diversification is widely recommended, and which risk it actually reduces, and which it cannot, is frequently glossed over. Understanding that distinction precisely is the precondition for using diversification correctly.
Differences in Disclosure Quality Across Markets
The information companies disclose differs greatly across countries in quality, frequency and reliability. That difference directly affects the basis for investment judgement, and it is frequently underestimated.
Comparing Transaction Costs Across Markets
Trading in different countries' markets can carry costs that differ by an order of magnitude, and most of these costs do not appear in the quoted price. Their cumulative effect on long-run returns frequently exceeds what investors expect.
The Liquidity Reality of Frontier Markets
Frontier markets have a presence in indices and reporting that far exceeds their actual investability. The core of that gap is liquidity, and understanding the reality of liquidity matters more than assessing these markets' growth stories.
How Index Providers Move Billions
Index providers do not manage money, and their decisions nonetheless direct hundreds of billions of dollars. That influence comes from the growth of passive investing, and its workings have several details worth understanding.
Retail Share and Volatility Characteristics Across Markets
The proportion of retail trading in a market affects its short-term price behaviour and volatility characteristics. This structural difference explains why the intraday behaviour of some markets differs so noticeably from others.
The Dollar Cycle and Emerging Markets
The dollar's cycle of strength and weakness affects emerging markets more than most local factors do. The linkage runs through several specific channels, and their force differs across individual emerging markets.
The Drivers of Cross-Border Capital Flows
Cross-border capital flows can be large enough to dominate a market's short-term direction, and a substantial part of what drives them sits outside that market. Understanding these drivers helps separate local information from external capital.
How Cross-Market Correlation Changes in a Crisis
The benefit of diversification rests on markets being imperfectly correlated. That correlation rises during crises, so the protection weakens at exactly the moment it is most needed.
Why Sector Composition Differs So Much Across Markets
Two countries of similar economic size can have entirely different sector compositions in their equity markets. That difference affects the validity of cross-country comparison, and its causes do not fully match the structure of the economy itself.
How Pension Systems Shape Local Markets
A country's pension system determines how long-term capital enters the market, and that profoundly influences the structure, depth and volatility of the local market. The factor is slow and durable, and it is frequently overlooked.
The Size of Global Bond Markets and Its Effect on Equities
The global bond market is larger than the global equity market, and most investors allocate their attention the other way around. The state of the bond market affects equities through several channels, and understanding those channels is more useful than remembering the size.
The Cyclicality of Commodity Exporter Markets
Economies built on resource exports produce equity markets with stronger cyclical characteristics than most. The source and amplitude of that cycle determine the role such markets play in a global allocation.
How Sovereign Risk Enters Equity Valuation
The same company listed in different countries can carry systematically different valuations, and part of that has nothing to do with the company. It reflects how the market prices the country's overall risk.
How Tax Erodes Cross-Border Returns
Tax treatment of foreign investment is spread across several layers, and their combined effect regularly exceeds what investors expect. These costs can be established in advance and are rarely included in return estimates.
Depositary Receipts and Ordinary Shares: Two Prices, One Company
Depositary receipts let investors buy foreign companies in their own market and currency. The same company therefore has two prices, and the relationship between them has several details worth understanding.
Trading Session Overlap and the Distribution of Volatility
Global equity markets open across different time zones, and volatility is not spread evenly through a trading day. The structure of session overlap determines where liquidity and price discovery concentrate.
Pricing Multinationals in a Deglobalising World
A substantial part of what multinational companies are worth rests on the operating conditions globalisation provided. As those conditions change, valuations adjust in a way that differs from an ordinary cycle.
