KhizooologyThe Little Book of Common Sense Investing
Costs are controllable; future market performance is not.
Big Idea
Bogle argues for broad diversification, low costs, and patient ownership rather than trying to outguess the market.
Own broadly
An index fund holds a basket of businesses rather than relying on one successful prediction.
Costs compound
Fees reduce what investors keep, and their effects accumulate over time.
Market returns
Broad ownership seeks market participation; it does not promise a positive return every year.
Stay consistent
Frequent changes can add costs and turn a long-term plan into reactive trading.
Local context
Fund access, taxation, and suitable allocations depend on the investor's jurisdiction and circumstances.
Notooo Take
Compare the total costs of available options before comparing their recent returns.
