What this video covers
- Why Modern Portfolio Theory (MPT) evaluates investments at the portfolio level, not in isolation, and how a volatile asset can actually reduce total portfolio risk
- The Markowitz (MPT, 1952) versus William Sharpe (CAPM, 1964) name-and-date trap that the exam loves to bait
- What the efficient frontier represents: the highest expected return for each level of risk, measured by standard deviation
- Why portfolios below the frontier are suboptimal, and why no portfolio can sit above the frontier
- The risk-return tradeoff table mapping risk-averse, balanced, and aggressive investors to the right point on the curve
- Why the risk-free rate on the exam means U.S. Treasuries, and why every incremental return above it requires accepting risk
- How customer profile, diversification, correlation, beta, CAPM, alpha, and standard deviation each plug into the MPT umbrella
