老師,你好,2024mock b session 2,case 9,問題4這道題能講一下嗎?

(-0.23%) 23 bps were lost because the manager overweighed the corporate sector during a period when credit spreads widened (the benchmark corporate returns in each duration bucket were less than the government returns in those same duration buckets). - 為什么Benchmark Corporate returns < Govt returns 就說明credit spread wider ?
With a higher duration than the benchmark (8.17 compared with 7.19 for the benchmark), the manager likely expected the rates to fall and took a bullish position on long-term bonds (interest rates) by increasing exposure to the long end of the interest rate curve (e.g., investing 50% of the portfolio in the longest-duration bucket versus 30% for the benchmark).--- 問題1: 這里bullish position 是對long term bond price 看漲吧? 而不是看漲interest rate ? 問題2:increasing exposure to the long end of the interest rate curve --> 這句話就是說增加long term bond的exposure 對嗎?

而且二級的時候王老師說過,二類錯誤的嚴(yán)重程度高于一類錯誤,在這里拒絕一個好的經(jīng)理成本明顯低于雇傭了一個不好的經(jīng)理吧,拒絕好的說不定可以找到更好的,但雇傭了不好的可能帶來的是嚴(yán)重的虧損,明顯后者嚴(yán)重程度更高應(yīng)該屬于二類錯誤吧?
