Covariance Shrinkage and Cluster Allocation
These questions review the examples in the companion slides. Choose an answer, then check the explanation.
Question 1
For 21 correlated ETFs on 251 daily returns, the condition number \(\lambda_{\max}/\lambda_{\min}\) of the sample covariance will be of the order of…
- 1–10: daily returns are nearly uncorrelated
- 50–100
- Thousands — the smallest eigenvalues are almost pure noise
- Infinite — 21 assets need more than 251 days to invert
Question 2
Before running: which rule will have the lowest volatility, and which the highest turnover?
- Lowest vol: HRP; highest turnover: equal weight
- Lowest vol: min-variance (sample); highest turnover: min-variance (sample)
- Lowest vol: equal weight; highest turnover: HRP
- Lowest vol: min-variance (LW); highest turnover: HRP
