A.Reconstitution. B.packeting. C.buffering.解释：

嗨，爱思考的PZer你好：
目前答案是正确的。
同学看到的这个题目和答案，就是已经改好后的。
同学放心做就可以了。
我们看：manager B的portfolio股票数量多于benchmark。
因此：
manager B可以是packeting，因为股票数量大于等于benchmark。
manager B也可以是buffer。buffer的股票数量可以大于，可以等于，也可以小于benchmark。
manager B 不可能是reconstitute。因为Reconstitution必须是500只股票。
本题要选least likely的，因此选Reconstitution。
----------------------------------------------就算太阳没有迎着我们而来，我们正在朝着它而去，加油！

SolutionReconstitutioninvolves leting names thare no longer in the inx anaing names thathave been approvenew inx members. Therefore the holngs of the funhoulalways 500. 看了老师对其他问题的解答，理解了为什么packeting的方法会使得portfolio的股票数量只会大于或等于benchmark的股票数量，希望再进一步解答为什么buffer的方法会让股票数量大于，等于，小于都可以呢。知道buffer是设置一个安全垫，所以大于或者等于benchmark的股票数量能理解，只不过小于的话是怎么实现的呢，剔除掉组合中股票的一部分？不还是算一只么，谢谢。

NO.PZ202207040100000604 问题如下 inxing technique, the number of holngs in Manager B’s inx most likely illustrates: A.reconstituting. B.packeting. C.buffering. SolutionC is correct. Buffering involves establishing ranges arounbreakpoints thfine whether a stobelongs in one inx or another. Some inx provirs have aptepolicies intento limit stomigration problems ankeep trang costs low for investors who replicate inxes. Size rankings mchange ily with market primovements, so buffering makes inx transitions a more graanorrly process. long stocks remain within the buffer zone, they stin the current inx, ana result, the holngs of the funmexceethe holngs of the inx.A is incorrect. Reconstitution involves leting names thare no longer in the inx anaing names thhave been approvenew inx members. B is incorrect. Packeting involves splitting stopositions into multiple parts. For example, if a micstock’s capitalization increases anbreaches the breakpoint between the micanlarge-cinxes, a portion of the totholng is transferreto the large-cinx but the rest stays in the micinx. On the next reconstitution te if the stovalue remains large canall other qualifications are met, the remainr of the shares are moveout of the micinx into the large-cinx. 一个月了这道题答案还不修改？？？？？？？？？？？？？？？？
