Thanks, Jerry. Hope you're right about this week. Hadn't thought about MMs going short. Why would they have closed the deal at less than the 35p bid if they were short? Seems risky to me, but I must admit am not an expert on how they work.
This time is different from Sprott -- with Sprott, they didn't get all their shares on Friday, so they had to come back for some on Monday, and that kept it going. Pretty sure GDXJ got all of theirs.
Part of my thinking is that there may be some LTHs that had targeted 25p, and will now get out, or at least top slice. Monday seems like a day for profit-taking. I'm guessing, though, and very bad at timing markets.
I'm going to give my logic on this weighting thing because I can't see where I'm going wrong. If you can set me straight, would appreciate it. If I'm right, all the better:
1. Our weighting was set based on end of August MCAP, SP about 15p. That gave a 0.66% weighting, resulting in £33 million. That meant, at 27p, close to 120 million shares.
2. Assume a price of 27p still on 30 November. That should give a weighting of about 1.18% (if the rest of the index is stable). That's £53 million (assuming stable exchange rate).
4. The 120 million shares will still be worth £33 million.
5. Therefore, if the price is still at 27p 30 November, they'll be buying £20 million or thereabout.
There are two key sub-periods. The first is from end of quarter valuation (31/8) to the ETF rebalancing (18/9). Any changes in SP during this time unbalance the weighting. The second is from ETF rebalancing (share purchase) to end of month valuation. Changes in SP during this sub-period don't unbalance the weighting, because they are reflected in both the MCAP of the company and the value of the ETF's holding.
So, if GDXJ bought at 15p, changes after that would not skew the weighting. But changes between the valuation point and the purchase point do skew the weighting. As long as SP stays above 15, GDXJ is going to be buying again in December. How much they will buy depends on how far above 15 it is at the end of November.
That's my logic, shoot me down if I'm wrong.
