What this video covers

  • What beta actually measures, and why it captures only systematic (market) risk rather than total risk
  • How to interpret beta values above 1.0 (aggressive), below 1.0 (defensive), equal to 1.0 (market), and equal to 0 (risk-free)
  • Why beta is a double-edged sword: the same multiplier boosts upside and magnifies downside
  • What alpha measures, and why it is calculated as actual return minus CAPM-expected return
  • Why index funds target alpha of approximately zero by design, and why active managers must show positive alpha to justify their fees
  • How two funds with identical raw returns can have completely different alphas based on their betas
  • Why a risk-adjusted comparison using both alpha and beta is the only defensible fund selection method on the exam
