The Only Three Questions That Count by Kenneth L. Fisher

Investing by Knowing What Others Don't

An accessible investing guide that reduces investment decisions to three core considerations: the realistic upside and downside for a security, the probability of those outcomes, and the appropriate position size to reflect that risk/reward. It advocates disciplined, probabilistic thinking and expected-value analysis over gut feelings or market noise, combining valuation, time horizon and sentiment to identify mispriced opportunities. Packed with practical frameworks and examples, it stresses risk control, position sizing and learning from market inefficiencies to improve long-term returns.
