Summary: Risk Analysis in Investment Project Evaluation

This video provides a detailed overview of risk analysis methods applied to evaluating investment projects, emphasizing the importance of incorporating risk into decision-making beyond just net present value (NPV) calculations.

Key Concepts & Frameworks

Risk Definition: Risk is the variability of returns and the possibility of financial loss, particularly the chance that NPV < 0 (i.e., internal rate of return < cost of capital).

Sources of Risk in Projects: - Variability in cash flows, especially income/sales forecasts (most significant source). - Cost fluctuations due to raw materials, inflation, exchange rates. - Tax changes affecting expenses.

Risk Analysis Methods:

Sensitivity Analysis
- Tests project performance variability by changing one variable at a time (e.g., sales volume).
- Example: Project 1 shows high sensitivity with NPV ranging from negative to very high depending on sales; Project 2 shows less variability and risk.
Scenario Analysis
- Examines simultaneous changes in multiple variables (e.g., economic growth, inflation, sales volume).
- Useful for understanding project resilience under different macroeconomic conditions.
- Project 1 is more sensitive to macroeconomic changes than Project 2.
Decision Trees
- Uses probabilistic branching to evaluate multiple possible outcomes and their likelihoods.
- Incorporates probabilities for different NPVs to calculate expected NPV and variability (standard deviation).
- Example: Project 1 has a 40% chance of negative NPV; Project 2 has more stable probabilities with higher expected NPV ($8,418 vs. $2,375).
- Can model sequential decisions based on outcomes.
Simulation (Monte Carlo)
- Assigns probability distributions to key variables (income, costs) and runs multiple iterations to generate a distribution of NPVs.
- Provides a probabilistic range of outcomes rather than a single estimate.
- Helps estimate likelihood of positive vs. negative NPVs.
Certainty Equivalents
- Adjusts projected cash flows by a factor representing the value investors assign to uncertain future cash flows relative to certain ones.
- Example: Cash flows are discounted by certainty factors (e.g., 90%, 80%, 70%) before applying a risk-free discount rate to calculate adjusted NPV.
Risk-Adjusted Discount Rate (RAD)
- Adjusts the discount rate upward to compensate for higher project risk.
- Balances between undervaluing risky projects (too low rate) and being overly conservative (too high rate).
- Goal: Find an appropriate discount rate reflecting the true risk to maximize company value.

Key Metrics & Examples

Initial investment examples: $50,000 for Projects 1 and 2; $15,000 in certainty equivalent example.
NPVs vary widely based on risk and scenario:
- Project 1 NPV range: -$12,500 to $31,500 (high variability).
- Project 2 NPV range: $2,650 to $14,120 (lower variability).
Expected NPV calculation using probabilities:
- Project 1: $2,375
- Project 2: $8,418
Certainty equivalent adjusted NPV example: $7,721 (vs. unadjusted higher cash flows).

Actionable Recommendations

Always incorporate risk analysis beyond simple NPV to make more informed investment decisions.
Use sensitivity analysis to identify which variables most impact project viability.
Apply scenario analysis to understand project performance under different economic conditions.
Utilize decision trees when dealing with multiple probabilistic outcomes and sequential decisions.
Employ simulation to capture a full range of possible outcomes and their probabilities.
Consider certainty equivalents to translate uncertain cash flows into risk-adjusted equivalents.
Adjust discount rates appropriately to reflect project risk, avoiding over- or underestimation of project value.
