用paper return求IS(bps)的這個知識點在哪里啊，基礎班似乎沒印象講過??？
為何能減少波動率？
這里比較的是絕對的標準差，top-down下標準差歸因不能通過行業(yè)的收益標準差和選股的收益標準差衡量嗎，為什么說是沒有，這里解釋的邏輯不合理啊
pov和vwap有什么區(qū)別，都是按照交易量交易的
衍生品難道還比fixed-income流動性還更好嗎，fixed income的大單都需要人工平臺去解決，為什么derivative僅靠DMA就能解決？兩個發(fā)行量的規(guī)模都不一樣吧
四因子模型是top down 還是bottom up
請講解一下
在mgr style analysis中，outdated的data是不是holding和return based的analysis都不合適，不存在誰更好？因為return based也是反映一段時間的風格？（refer 2024 mock A PM case 9 第3問）
Chasing Alpha Research Case Scenario 第一題 The most appropriate performance allocation method to evaluate the effectiveness of the big data strategy is: returns-based. holdings-based. transactions-based.
官網(wǎng)題Chasing Alpha 第二題 的官網(wǎng)解析不太理解：A is correct. Given that the fund mandate requirement is for a short-term return in excess of the risk-free rate, the Sortino ratio is a more appropriate measure because it penalizes returns below a specific return—in this case, 1.5% above the risk-free rate.B is incorrect. The Treynor ratio penalizes returns below the risk-free rate. It will not measure the fund’s ability to meet the requirement of a short-term return in excess of the risk-free rate.C is incorrect. The information ratio evaluates the portfolio return relative to a benchmark. It will not measure the fund’s ability to meet the requirement of a short-term return in excess of the risk-free rate.
老師，按曹老師解釋的，price-target用于短期alpha，有target price，有止盈位置，題目中不是有l(wèi)imit嗎，第一段還有temporary mispricing to open position，也是指短期alpha，那為什么不用price-target？是因為市場過度反應，現(xiàn)在的估價遠低于$28的公允價值，即只把28作為一個考慮策略的基準嗎？
老師，這里哪里說明了是用BF model 而不是BHB 方法
問一個與答題無關的問題：Liu was able to execute the order over the course of 30 minutes and received an average price of $50.55. The price at the time the order was placed is $50.45. The volume weighted average price (VWAP) over the trading horizon was $50.52, 請問這里的50.55和50.52都是指實際成交均價對嗎，計算或含義上有什么區(qū)別？謝謝
您好 請問為什么和dealer是dealer承擔風險 而和broker是自己承擔風險呢？
請問這里怎么通過超配了長期債并且longterm的curve effect>0去判斷出yield curve變flatter了呢？
