Monica Popkirk Case Scenario

Monica Popkirk directs the equity manager selection team of PV-America Wealth Management (“PV”). She and her analysts evaluate, classify, and recommend funds to the PV investment committee. PV has asked Popkirk to broaden the selection of approved funds for its investment advisers to use in client portfolios and also to include some alternative asset classes by possibly using some hedge funds.

Popkirk and her team examine the fund descriptions and consider both holdings-based and returns-based approaches to style classification. Intending to select a top-down fundamentally driven manager, she considers three candidates from Lunnar Associates, as shown in Exhibit 1.

Exhibit 1

Lunnar Associates Funds under Consideration


Beyond the fund descriptions, Popkirk instructs her team to assemble an analysis table to help determine which of Lunnar’s funds has the closest fit to the style of its chosen benchmark index. She points out that all three of these funds are long only with well-known and accepted style box categories. Data are provided for both the holdings-based style analysis of the current portfolio and the returns-based style analysis based on 36 months of historical returns and are shown in Exhibit 2.

Exhibit 2

Lunnar Fund Style Analysis


Popkirk explains to her analysts that the better active fund managers wisely consider what pitfalls and behavioral biases may readily affect their strategies and those of their competitors. For instance, when evaluating the fundamental approach used by Lunnar C, Popkirk says that analysts should look for evidence that one of the following three biases have been acknowledged and addressed by the manager: survivorship bias, confirmation bias, or look-ahead bias.

Digging deeper into another one of Lunnar’s funds, Popkirk’s analysts review and discuss the Lunnar fund’s annual reports for the last six years. One of the reports noted, “During the last recession, we rotated into deep-value companies likely to deliver superior returns as a risk-on environment returned.”

The analysts then make the following comments:

  • Analyst 1: “The fund is following a top-down approach.”

  • Analyst 2: “I disagree. The emphasis on economic analysis is consistent with top down, but because it uses deep-value stocks, the approach is clearly bottom up.”

  • Analyst 3: “After reading the reports for all years, I was left thinking that overall they are GARP managers—growth at a reasonable price—which is top down.”

One of PV’s committee members has asked Popkirk for her thoughts as to which style classification should be used when describing Lunnar’s popular hedge fund, the Lunnar Hedge-X fund. It uses a variety of techniques to achieve alpha, including long–short equity portfolios with substantial futures and options overlays to control risk. Lunnar suggests its clients use a combination of the Lunnar Hedge-X fund along with its more traditional funds to improve the Sharpe ratio of its overall portfolios.

Boris Thompson, one of the Lunnar managers, claims to have had consistent success in beating his benchmark by using price momentum as a rewarded equity factor exposure. Popkirk warns her analysts that the manager may not be truly forthcoming regarding some periods of underperformance.

Question


Based on the information in Exhibit 1, which of the funds from Lunnar Associates most likely follows a top-down fundamental approach?

选项:

A.

Lunnar A

B.

Lunnar B

C.

Lunnar C

解释:

B is correct. Lunnar B uses a top-down fundamental approach because it requires manager discretion in considering future long-term trends and short-term opportunities in the global economy (i.e., a fundamental approach). The strategy is executed by using different portfolio weightings on indexes rather than individual corporate securities, making it top down rather than bottom up.

A is incorrect. Lunnar A is passively managed because the portfolio weights are set without input from the fund manager’s future beliefs.

C is incorrect. Lunnar C is actively managed but uses a bottom-up strategy focused on the expected future prospects of individual securities.

嗨,爱思考的PZer你好:


Top down是指利用先分析宏观,再分析行业,最后看个股,比较关注宏观因子。例如经济增长率、通胀、利率等。

我们看到B选项,使用了经济增长率这一个宏观指标,因此属于top down。同时B选项,需要用到view,对未来的观点,属于fundamental。



A是说,用value因子投资于10个国家。A是以一种固定的规则在做投资,并不包含对未来的预期,本质是一种量化方法。不是基本面方法。
