POV的缺点为什么会higher trading cost在adverse market情况下,谢谢

NO.PZ2020020202000001

问题如下:

Which of the following statements regarding the execution algorithms is incorrect?

选项:

A.

POV algorithm trades a predetermined number of shares within the specified time interval.

B.

VWAP algorithms slice the order into smaller amounts to send to the market following a time slicing schedule based on historical intraday volume profiles.

C.

TWAP algorithms slice the order into smaller amounts to send to the market following an equal-weighted time schedule.

解释:

A is correct. VWAP and TWAP algorithms follow a time-specified schedule, trading a predetermined number of shares within the specified time interval, rather than the POV algorithm. The other two statements are both correct.

讲义上higher trading cost by continuing to buy as price move higer and to sell as prices move lower,这是为什么,求详解,谢谢

是因为这个情况下,大家抢着交易吗?交易量大。

你提到的“higher trading cost by continuing to buy as price move higher and to sell as prices move lower”是指在价格上涨时继续买入或价格下跌时继续卖出,会导致更高的交易成本。这是因为:

大量买入会推高价格,大量卖出会压低价格,导致你实际成交的价格不如预期。随着价格变动,市场流动性可能减少,买卖价差扩大,进一步增加成本。大额交易可能暴露你的意图,其他交易者可能抢先行动,加剧价格不利变动。

因此,持续追涨杀跌会增加交易成本,尤其是在市场流动性不足或信息敏感时。
