Erik Brecksen, CFA, a portfolio manager at Apfelbaum Kapital, recently recruited Hans Grohl, a CFA candidate and recent MBA graduate from a top university with excellent quantitative analysis skills. Apfelbaum Kapital stresses “top-down” fundamental analysis and uses a team approach to investment management. The firm's investment professionals, all of whom are CFA charterholders or candidates, attend weekly investment committee meetings. At the meetings, analysts responsible for different industrial sectors present their research and recommendations. Following each presentation, the investment committee, consisting of senior portfolio managers, questions the analyst about the recommendation. If the majority of the committee agrees with the recommendation, the recommendation is approved and the stock is placed on a restricted list while the firm executes the necessary trades.Apfelbaum considers its research proprietary. It is intended for the sole use of its investment professionals and is not distributed outside the firm. The names of all the investment personnel associated with the sector or investment class are listed on each research report regardless of their actual level of contribution to the report.On Grohl's first day of work, Brecksen assigns him responsibility for a company that Brecksen covered previously. He provides Grohl with his past research including all of his files and reports. Brecksen instructs Grohl to report back when he has finished his research and is ready to submit his own research report on the company.Grohl reads Brecksen's old reports before studying the financial statements of the company and its competitors. Taking advantage of his quantitative analysis skills, Grohl then conducts a detailed multi-factor analysis. Afterward, he produces a written buy recommendation using Brecksen's old research reports as a guide for format and submits a draft to Brecksen for review.Brecksen reviews the work and indicates that he is not familiar with multi-factor analysis. He tells Grohl that he agrees with the buy recommendation, but instructs Grohl to omit the multi-factor analysis from the report. Grohl attempts to defend his research methodology, but is interrupted when Brecksen accepts a phone call. Grohl follows Brecksen's instructions and removes all mention of the multi-factor analysis from the final report. Brecksen presents the completed report at the weekly meeting with both his and Grohl's names listed on the document. After Brecksen's initial presentation, the committee turns to Grohl and asks about his research. Grohl takes the opportunity to mention the multi-factor analysis. Satisfied, the committee votes in favor of the recommendation and congratulates Grohl on his work.Ottie Zardt, CFA, has worked as a real estate analyst for Apfelbaum for the past 18 months. A new independent rating service has determined that Zardt's recommendations have resulted in an excess return of 12% versus the industry's return of 2.7% for the past twelve months. After learning about the rating service, Zardt immediately updates the promotional material he is preparing for distribution at an upcoming industry conference. He includes a reference to the rating service and quotes its returns results and other information. Before distributing the material at the conference, he adds a footnote stating “Past performance is no guarantee of future success.”
