請問 reading 13 Practice Problem Q2 Theoretically, higher-risk assets would warrant a narrow corridor because high-risk assets are more likely to stray from the desired strategic asset allocation. However, narrow corridors will likely result in more frequent rebalancing and increased transaction costs, so in practice corridor width is often specified to be proportionally greater the higher the asset class’s volatility. Thus, higher-risk assets should have a wider corridor to avoid frequent, costly rebalancing costs. 請問課本中是寫The higher the volatility, the narrower the optimal corridor. 哪個是正確的？
