Key ideas in Portfolio Construction and Risk
- Purchasing power measures what your invested capital can actually buy in the economy.
- Nominal return minus the inflation rate yields your real return in purchasing power.
- A positive nominal gain during higher inflation still leaves you poorer in real goods.
- Maximum drawdown measures the worst peak-to-trough drop before a new high.
- Recovery duration tracks the full time required to climb back to prior peaks.
- Annualized volatility smooths out multi-year pain into an average standard deviation.
- Higher nominal returns often reflect leverage or extreme downside exposure rather than skill.
- Risk-adjusted ratios compare excess returns directly against the volatility assumed.
- The Sharpe ratio divides excess return over the risk-free rate by total volatility.
- A 50% loss requires a 100% gain just to restore your original baseline capital.
- Volatility drag ensures wide return swings depress compound geometric growth rates.
- The geometric mean of uneven returns is mathematically lower than the arithmetic average.
- Liquidating shares during an early downturn locks in paper losses permanently.
- Withdrawing capital from a depleted base leaves fewer shares to compound in a recovery.
- Poor returns early in retirement threaten solvency far more than poor returns late in life.
- Adding more stocks in the same sector fails to diversify because their prices move in lockstep.
