Boyobach - look away from both OCDO and the shorting aspect for a moment.
The companies you list from your watchlist are all 'relatively' smaller in terms of the market, and even then you have shown that the pattern exists in some of them as well. I mentioned to look at most large companies. I have nearly 200 shares on various watchlists (don't ask) and if you look at the FTSE100s in particular - banks, miners, RR, BAT, Diageo, M&S etc. - all exhibited the exact same pattern yesterday. ABF - volume and value nearly 10x avg UT went through in Friday's!
You point out that other than the Kroger day you haven't seen that volume for OCDO - you can apply the same logic to many other companies who will now be the same as a result of this 'event', whatever it was.
This is the link to the official stock market trades for last week so you can see what I mean by the total volumes and value yesterday - it is across the board to cause that kind of spike:

"it is unsatisfactorily opaque" - I agree entirely, and am struggling to tie it down to any one thing. I'm not done researching though because it's a curious market dynamic.
"and may sometimes be associated with shorted stocks" - maybe, but also here associated with many, many more non shorted stocks so not a clear conclusion.
"It does beg the question, if it is an institutional process, why is it not conducted off the exchange - why via the auction?" - I really like this question but don't know the answer, although I suspect it's to do with transparency. The closing auction has become more and more of a key event in recent years. Triple witching was mentioned before and you will see a very similar thing in the UT on that day, across the board, when contracts expire/rolled over etc.
Institutions do what they do and most of the time we are just passengers, but things like this rarely have a significant measurable impact on the market from one day to the next. Open tomorrow will tell all but I'm not expecting any great shakes (although maybe, hopefully, a market wide uplift from the US market events on Friday).
DonBroco - similar answer for you regarding STJ. It's not just them and OCDO, it's almost every FTSE350 company, so it's not logical to conclude that it has anything to do with just those few that may exit due to the index rebalancing, which doesn't happen until 24 June in any case.
