That's an impossible question to answer. The index fund managers are in charge of how many shares of each stock they purchase for that index. They are most likely constantly trading in and out of positions much like I do and a lot of others.
They simply purchase the shares off of the General market just like you and I do on a daily basis. They probably dollar cost average in and out of positions as well. I don't think we're going to see a ridiculous rush into the shares. Fund managers are pretty call the cool and collected when it comes to accumulating and like us they enjoy purchasing on retracements. The goal is to get in as cheap as possible. I just hope David doesn't perform an ATM in the month of July but if he does I'm curious to know if it's going to be at a discount to where the shares are presently trading at that time
