Nah, it finished there a week or so ago as well, and has been that high over the course of other days. It's moving in sympathy with the AGL price.
That said, I've been surprised at the size of holdings from the instos that have bought in since, particularly Deutsche (greater than AGL!). It could be just a clever way of putting a floor on the AGL price, i.e. it's basically a free put at 0.15 for them, which is relevant given current volatility.
However, is that all it is? I suspect so, but that's what I'm struggling with.
