This section builds upon the previous concept of the ‘u-shape’change in tracking error – the initial improvement and subsequent reversal of tracking error as more index securities are added to a portfolio. Several factors contribute to tracking error:
Managing tracking error involves balancing the trade-offs between staying faithful to a benchmark index and the associated costs. In an ideal scenario, portfolio managers would closely match the number of constituent securities and their weights with the benchmark index. However, real-world factors like trading costs and fees lead to deviations in actual investment performance compared to the index.
Passive investing doesn't mean no trading activity. Managers engage in trading to manage cash flows, reinvest dividends, and adjust for changes in the index's constituents. It's common for passive portfolio managers to minimize cash holdings because having cash can lead to unwanted tracking error. To reduce tracking error, portfolio managers aim to invest cash flows at valuations similar to those used by the benchmark index provider. When that's not possible, they strive to maintain a beta of 1.0 relative to the benchmark index while aligning other risk factor exposures with the index.
Question
Less liquid securities create tracking error in a passively managed portfolio by:
- Increasing cash drag.
- Increasing management fees.
- Increasing trading costs.
Solution
The correct answer is C.
Less liquid securities can contribute to tracking error in a passively managed portfolio by increasing trading costs. When you need to buy or sell less liquid securities, you may face wider bid-ask spreads and experience difficulty in executing large orders without affecting the market price. The higher trading costs associated with these challenges can lead to deviations from the target benchmark index, creating tracking error.
A is incorrect. Less liquid securities can indeed contribute to tracking error, but it's not because they directly increase cash drag. Cash drag refers to the portion of the portfolio that is held in cash or cash equivalents and is not invested in securities that track the benchmark index. It can result from having cash on hand due to inflows, outflows, or other reasons. Less liquid securities may indirectly contribute to cash drag if trading them is difficult or costly, but the primary impact is on trading costs, not cash drag.
B is incorrect. Less liquid securities do not directly impact management fees. Management fees are typically fixed or based on the assets under management, and they are not directly related to the liquidity of the securities in the portfolio. Management fees represent the costs charged by the fund manager for managing the portfolio but are not influenced by the liquidity of the underlying securities.
