Given the stock has gone ex-dividend to the tune of 11.5c, this means that, effectively, from a the position of someone who has been short-positioned cum-dividend, as you have, the dividend-adjusted price is now 657c.
Even as a shareholder, I am somewhat bemused by the share price response to the result, so I can imagine how utterly perplexing it must be to you.
Maybe short some more?
