Investing principles

Twelve principles that separate investors who build wealth from those who do not — each one checked against decades of market data.

Rule number one: surviveYou can only compound money you still have. Why avoiding large losses matters more than chasing large gains. 4 min → Why you need a repeatable processAn investment process is a recipe: the same inputs lead to the same decision. That makes results measurable — and emotions manageable. 4 min → Consistency beats brillianceInvesting a fixed amount every month — through crashes and booms — is one of the most powerful habits in personal finance. 4 min → No exposure, no upside — but avoid the worstMissing a few of the best months costs a fortune. Missing a few of the worst earns one. What that means for how you invest. 5 min → Asymmetry: cut the left tail, keep the rightGood investments have more upside than downside. How to build that asymmetry into a portfolio — and what it looks like in the data. 4 min → Time is your edgeOver one year, stocks are a gamble. Over 15 years, they have never lost money in our data. Why your time horizon changes everything. 4 min → The order of returns mattersTwo investors with exactly the same yearly returns can end with very different wealth. Why a crash early in retirement is so dangerous. 4 min → Why a few winners drive most of the returnsReturns are not evenly spread: a minority of markets, stocks and months produce most of the gains. How to make sure you own them. 4 min → Nobody knows what the market will do nextForecasts are entertainment. Most daily and monthly moves are noise. How to invest without needing to know the future. 4 min → Do less, profit moreActivity feels productive, but every trade costs money and invites mistakes. Why the best investors are often the least busy. 4 min → What returns are realistic?Promises of 50% a year are a red flag. What long-term returns stocks, bonds and gold have really delivered — and what the best investors achieved. 5 min → Crashes: where long-term returns are made — if you survive themCorrections every few years, deep bear markets every decade. How often markets crash, what happens afterwards and how to be ready. 5 min →
