  • Systematic Risk (Market Risk) cannot be eliminated through diversification (Beta).
  • Unsystematic Risk (Business/Credit Risk) CAN be eliminated through proper asset class diversification.
  • Capital Market Line (CML) measures return against total risk; Security Market Line (SML) measures return against systematic risk (Beta).
