老師您好!這道題的C選項(xiàng)確實(shí)讓我猶豫了一下,圖中題目2,當(dāng)時(shí)老師講的時(shí)候是說securitization product一般期限比較長需要放在banking book中所以2是錯誤的,這道題巧了正好有一樣的表述,請老師幫忙看看明確一下?
App提問
Q2解析與視頻講解不一致?。?!
這個講解視頻好像放錯了
Q1 如果是non monetary assets 應(yīng)該如何折算,以及如果是在us gaap下,hyperinflation 應(yīng)該如何折算?
市場風(fēng)險(xiǎn)var是否應(yīng)該轉(zhuǎn)化10天的var。這題里算的是一天的。
EBITDA這個指標(biāo)是將所有公司放在同一個情況下比較,但是衡量企業(yè)盈利狀況只剔除稅和折舊攤銷,通過“NI+支付利息”衡量不是更好?
老師,這里的0.8%是兩個數(shù)值相減之后的結(jié)果,那支出為什么直接是3.6呀?
老師這道題為什么和官網(wǎng)不一樣,官網(wǎng)是:A quantitative analyst at a proprietary trading firm is incorporating unsupervised machine learning (ML) algorithms into the firm’s technical analysis of equities by using K-means clustering. The clustering algorithm will be applied to continuous volatility data in order to group observations into clusters that can be used to identify the current market regime. Since clusters close to each other are likely to exhibit similar characteristics, the analyst measures the distances between the observations within each cluster and the centroid of that cluster. If the analyst wants to ensure that the minimum distance is obtained for the continuous data clusters when applying the K-means algorithm, which measure should be used to achieve the desired outcome? A.Euclidean distance B.Manhattan distance C.Cook’s distance D.Gini measure麻煩解答一下
老師這里應(yīng)該是減去3吧?
老師,第五題再補(bǔ)充一個問題,這里面遠(yuǎn)期和期貨之間的差異和多空有關(guān)系嗎,如果這道題換成多方的話結(jié)論是什么呢?
老師,第五題可以這么理解嗎?對于期貨合約,短期內(nèi)即使標(biāo)的資產(chǎn)價(jià)格變化,它的合約價(jià)值可能為零,但空頭的收益已體現(xiàn)在保證金賬戶上。對于遠(yuǎn)期合約,空頭方的浮盈會直接反映在合約的市場價(jià)值上。因此,在相同的標(biāo)的資產(chǎn)價(jià)格變化下,期貨合約的價(jià)值通常小于遠(yuǎn)期合約的價(jià)值。
這里的EE是不是也應(yīng)該是現(xiàn)值?
這里分母為什么不是r-g而是r?
老師可以舉一個計(jì)算kurtosis的例子嗎,想看一下計(jì)算過程,就是用這個公式怎么計(jì)算
