Explanation
Appraisal-based real estate indexes tend to lead to overestimation of the diversification benefits from private real estate (Option C). Here's why:
Key Characteristics of Appraisal-Based Indexes:
- Smoothing Effect: Appraisal-based indexes use periodic property valuations rather than actual transaction prices, which creates a smoothing effect on returns
- Lower Volatility: The smoothing effect artificially reduces the measured volatility of real estate returns
- Correlation Distortion: The lower volatility leads to artificially low correlations with other asset classes
Why Option C is Correct:
- The artificially low volatility and correlations make private real estate appear more diversifying than it actually is
- Investors may overestimate the diversification benefits when relying on appraisal-based indexes
- This can lead to suboptimal portfolio construction decisions
Why Other Options are Incorrect:
- Option A: Appraisal-based indexes actually underestimate volatility due to smoothing, not overestimate it
- Option B: Appraisal-based indexes typically lag transaction-based indexes because appraisals reflect past market conditions rather than current transactions
Real-World Implications:
- Investors should be aware of this bias when evaluating private real estate investments
- Transaction-based indexes provide more accurate measures of true market volatility and correlations
- The smoothing effect can mask the true risk characteristics of real estate assets
This understanding is crucial for CFA candidates analyzing alternative investments and portfolio construction.
