L3V3 P270 EXAMPLE 8. In the exam, is the highlighted sentence well enough to get a full mark for this question?

If an investor want to choose stocks under growth approach, should he evaluate the YoY growth for revenue or net income? Is there any difference between these two?

L3V3 p239. In Example B, company C's forward P/E is 2.2, which is absolutely and relatively low compared to other companies. (1) why should not this stock be a good candidate under the relative valuation approach？ （2）The solution said it's a good candidate under the deep-value approach. Through definition, deep-value approach chooses low P/B company and company under financial distress. How can I tell the P/B is low and it is under financial distress?

L3V3 P202. I'd like to ask something about the tracking error and transaction cost. (1) If the tracking error measures the divergence in portfolio price and benchmark price, does that mean whatever causes the price difference could affect the tracking error? (2) In the diagram, why is the "tracking error gross of trading cost" continuously declining when both tracking error and transaction cost are increasing? (3) How to guarantee a convex U-shape but not a concave U-shape? If the first security purchased for the portfolio is illiquid, then transaction cost dominates and tracking error should increase.

關(guān)于active share和active risk，我對這個回答還是有點懵…怎么理解有active risk一定有active share呢？我理解，解答是想說如果active share=0，是不是就代表active factor risk和specific risk都是0了？根據(jù)active share的定義，sizing和number是影響它的因素。active risk中factor部分就對應(yīng)sizing，specific就對應(yīng)股票的數(shù)量么？

L3V3, P185. For an equally weighted portfolio, why is the HHI 1/n not 1/ (n^2) ?

請教一下老師Reading17課后題第一個case感覺看不太懂，尤其是2、3、4、6題，可否指教，感謝！

老師，碰到show your caculation的題用語言（非數(shù)字）描述步驟能拿過程分嗎
