I doubt they were redeemed shares but simple block trades bought PM/AH. If they were redeemed the price would be closer to market as all OIHers are up. Market makers rule and often have left overs from a gap up.
Oil is not peaked just yet, give it a few days. I think it would be more of a pullback in the market that you need more so than oil pulling back to bring OIH into the $160's. We learned that last year the hard way. Given the core inflation alone would keep this above $150 in a serious mraket correction. You have to remember that at this price level a 20 point pull back would not equal the percentage of pull back a year ago. Conversely a 10 point run up is trivial as far as a percentage play. I hope I am making sense, I am on cold medecine. Not for recreation LOL I really have a cold.

I posted twice today about what you would see in the AH and that the redemption trades and rebalances would likely not post intraday. It's program trading between computers and you can not participate.
However, there was an event where many redemption trades were taking place in AH and it either triggered stop alerts or people just got freaked and covered. I was able to sell short 2 points higher than the close and cleaned up on the gap fade. I was kind of funny and sad at the same time.
