Finance Theory — 18.2: Profitability Index and the Scale Problem

Would you rather turn $1 into $2 or $10 million into $15 million? The profitability index says pick the first option — but that choice leaves you nearly $5 million poorer. This video explains why ratio-based metrics break down when comparing projects of different sizes, and why NPV remains the gold standard in capital budgeting. Key concepts covered: • Profitability Index (PI) formula: present value of future cash flows divided by initial investment • PI decision rule: PI greater than 1 means accept, PI less than 1 means reject • Why PI and NPV always agree on standalone accept/reject decisions • The scale problem: how PI misleads when ranking mutually exclusive projects • Diminishing marginal returns and optimal capital deployment • Real-world case study: the subprime mortgage crisis and what happens when capital ignores diminishing returns • Why rate-of-return frameworks break down at institutional scale (sovereign wealth funds, large pension funds) • Decision framework: when to use PI vs. NPV — standalone decisions, mutually exclusive projects, and capital rationing • Why shareholders care about dollars created, not ratios achieved ━━━━━━━━━━━━━━━━━━━━━━━━ SOURCE MATERIALS The source materials for this video are from    • Ses 18: Capital Budgeting II & Efficient M...
