why release ann on day stk is to be sold off

I went to bed with this puzzle rolling about in my brain and funny enough woke up with the same puzzle rolling in there this morning.

Why did Lynas release the FFK Ann on the same day they knew there was to be a very large sell off of its stock due to LYC be removed from the index. I would prefer we discuss this with a level head, no witch hunts please unless there really needs to be one!

My outcomes were either:

1. They thought it would support the share price, and maybe it did who knows where it could have ended up with that size of selloff with no good news in the air.

2. Someone is asleep at the wheel within the LYC PR department and did not think this through. This would amount to negligence in my books.

I only have a tiny brain so that’s the best I could come up with. I know there are some very clever cookies on here so can anyone offer any other constructive conclusions on this matter as it blows me (not literally of course)

At this time we need a sentiment "I don't know anymore" my attempt at humour.
