在求最优组合时为什么sharp ratio 和SFR 选择结果不一样



Tina Swan Case Scenario

Tina Swan heads a consulting practice that advises large funds and high-net-worth individuals about portfolio asset allocation and portfolio performance. Swan and two junior advisers, Stephanie Gruber and Monica Morrison, are meeting with a client, XTR Funds (XTR), to select an appropriate mean–variance-optimized (MVO) portfolio combination that meets various restrictions. Three possible portfolios meet XTR’s criteria; each portfolio’s expected performance is higher than XTR’s target return of 5.7% (Exhibit 1). Consequently, each prospective portfolio can be combined with a risk-free security to generate XTR’s target return.

EXHIBIT 1

MEAN–VARIANCE-OPTIMIZED (MVO) PORTFOLIOS

MVO portfolioExpected return (%)Return standard deviation (%)Portfolio weight in risk-free security (%)*
A9.518.6949.35
B8.214.9539.06
C7.814.1835.00

Risk-free security expected return: 1.8%

XTR target return: 5.7%

* This is the proportional investment in the risk-free security that in combination with the associated MVO portfolio produces the target expected return of 5.7%.

官网的练习题,但我想问的时候两个公式结果不一致,怎么选择

看题目要求,这道题问“highest probability of meeting the committee’s desired return criteria”,要求的收益率是5.7%,就得用SFR来计算

Shimin_CPA税法主讲、CFA教研 · 2018年12月01日

sharpe ratio 和SFR 公式是不同的。一个分子减的是Rf 1.8%,一个减的是targe return 5.7%.

另外,请问题目出处。
