Financial markets are unpredictable. Even when a trading strategy has a positive expectancy, a few bad trades can wipe out an account if position sizes are too large or emotions override discipline. Academic studies show that how much capital is allocated per trade is more influential on long‑term returns than the specific trading system used. For example, research cited by position‑sizing specialist Van Tharp found that portfolio performance variability was overwhelmingly explained by position‑sizing decisions rather than the underlying strategy. This suggests that money management is not a peripheral task but the core engine that preserves capital and compounding power.
