RE:When will they stop buying?Good question. Someone posted that GSV would comprise 1.43% of GDXJ, a US $5.2 billion fund. Using very round numbers, 1.43% is $74,360,000. It is hard to guess the average price paid. In this case, I'll use US $2.55, but your guess may be better. Using $2.55 you get a ballpark figure of 29,160,784. Well, if the stock trades around 1.5million shares a day, do you suppose GDXJ's buys are 2/3rd of that? Even with different assumptions, they could have a ways to go. Your mileage may vary.
