Assuming arbitrage costs are minimal, which of the following is most likely to occur when the share price of an ETF is trading at a premium to its intraday NAV ?
选项：
A.New ETF shares will be created by the ETF sponsor.
Redemption baskets will be received by APs from the ETF sponsor.
Retail investors will exchange baskets of securities that the ETF tracks for creation units.
解释：
A is correct. When the share price of an ETF is trading at a premium to its intraday NAV and assuming arbitrage costs are minimal, APs will step in and take advantage of the arbitrage. Specifically, APs will step in and buy the basket of securities that the ETF tracks (the creation basket) and exchange it with the ETF provider for new ETF shares (a creation unit). These new shares received by APs can then be sold on the open market to realize arbitrage profits.
ETF市场价高于NAV，AP会在二级市场上卖ETF，买入一篮子股票，一级市场上向ETF发行人申购，这是个CREATION过程，为什么C不对呢？
