Books worth a decade

On the case for long-term ownership

  • The Little Book of Common Sense Investing — John C. Bogle. The index-fund argument from its inventor, in an evening's read.
  • Stocks for the Long Run — Jeremy Siegel. The standard reference on multi-decade asset returns and what drives them.
  • Common Stocks and Uncommon Profits — Philip Fisher. For the satellite portion: what "quality worth holding forever" actually means.

On behavior — the harder half

  • The Psychology of Money — Morgan Housel. Why reasonable beats optimal, and staying wealthy differs from getting wealthy.
  • Your Money and Your Brain — Jason Zweig. What your own neurology does to you in bubbles and crashes.
  • A Random Walk Down Wall Street — Burton Malkiel. The classic inoculation against systems, patterns, and hot tips.

Glossary

The terms this site leans on

Total return

Price change plus reinvested dividends. Long-run market statistics quoted on this site are total returns unless stated otherwise — over 30 years, reinvested dividends are a huge share of the outcome.

Nominal vs. real return

Nominal is the headline number; real is after inflation. The S&P 500's ~10% nominal long-run average is roughly 7% real. For decades-long planning, real is the number that buys groceries.

Index fund / ETF

A fund that mechanically holds every constituent of an index (like the S&P 500) at market weight, at very low cost. An ETF is simply an index (or other) fund that trades on an exchange like a stock.

Dollar-cost averaging (DCA)

Investing a fixed amount on a fixed schedule regardless of price. Guarantees you buy more shares when prices are low and fewer when high, and removes timing decisions entirely. See Strategy.

Drawdown / bear market

A drawdown is the fall from a peak to a trough; a bear market conventionally means a 20%+ decline. A 30-year plan should expect several. The recovery, not the decline, is where patient investors get paid.

CAPE (Shiller P/E)

Price divided by ten-year average inflation-adjusted earnings. Useful as a rough gauge of how expensive a market is versus its own history — and of why expected returns from very high starting valuations tend to be lower. Useless as a timing tool.

Sequence-of-returns risk

The risk that the order of returns hurts you even if the average is fine — a crash just before or after you start spending from the portfolio does far more damage than the same crash mid-accumulation. The reason allocations glide toward bonds as the goal nears.

NISA / iDeCo (Japan)

Japan's tax-free investment account (reformed in 2024: ¥3.6M annual, ¥18M lifetime capacity, indefinitely tax-free) and its locked-until-60 personal pension with income-deductible contributions. See Accounts & Tax.

연금저축 / IRP / ISA (Korea)

Korea's pension savings fund and individual retirement pension (tax credits plus tax-deferred growth, for Korean-listed funds), and the individual savings account with partly tax-free gains. See Accounts & Tax.

W-8BEN

The US tax form a non-US investor files with their broker to claim treaty withholding rates on US dividends (10% for Japan, 15% for Korea, instead of the 30% default).

Korea discount / Value-up

The persistent valuation gap between Korean companies and global peers, attributed to governance and payout practices — and the 2024 government program (modeled on Japan's reforms) aimed at closing it. See Markets.
