Indeed. Market makers are generally good enough at their job to avoid being left holding the baby unless they want to. Certainly not to the tune of nearly 20% of the company.
The other thing to remember, as I've pointed out before, is that they've been the largest shareholder over at TRP for some time. That's not been a stock in gentle decline, so the same reasoning wouldn't work over there. In fact, the TRP management speak highly of them as a significant shareholder. I posted a while back how PH had sold down some of their TRP at the same time as they topped up here. They actually sold more (in consideration) than they bought here, but after the latest TR1 they're probably about even. So they've transferred a small amount of the capital they had tied up in TRP over to here. But the word is small. In ADME and TRP they've held a broadly level position - in TRP for quite some time.
As you say, we can speculate all we like as to why they're doing this. We'd be guessing. But it seems clear enough to me that their holding is deliberate, not an example of market maker incompetence where they've got stuck with shares by mistake, and can't avoid increasing their holding further. I haven't got L2 access, perhaps you have, but there's almost always more than one active market maker. If they were trying to reduce, they'd make sure that their bid is never top, so that they don't pick up the shares people try to sell. Instead, it seems they're actively stepping forwards to take them - when the price is right.
