A macro topic for this week’s fixed-income committee is the possibility that the US Federal Reserve Board (Fed) will raise the federal funds rate (FFR) 25 bps at their next meeting. Quantum’s committee believes that the Fed is likely to hold off raising the FFR for at least six months because of weak economic data, and that weakness will be seen in the upcoming payroll numbers. Quantum expects the monthly non-farm payroll report to show that the US labor market added only 90,000 jobs this month, roughly in line with consensus expectations. The committee is debating what will happen to the short end of the US yield curve (and what will happen subsequently to short-dated bond prices) if the payroll report comes in at the level they expect. 题干部分如上，题目如下 Q. Which of the following is the most likely impact on short-term bond prices if Quantum’s expectations regarding the payroll report are correct?

这应该是convex才对啊，怎么是concave呢？ 笑脸就是convex呀？

一，Corner组合不一定就是市场组合呀，那么为什么还说要把无风险资产和夏普比例最高的corner组合连接起来呢？ 二，难道意思是说选一个在已知的corner组合中选一个具有最高夏普比率的吗？ 谢谢!

请问为什么某一类资产权重为负的情况下就不能用corner组合来求解啊？

corner 组合是怎么得出的？怎么形成的？
