To be honest, the numbers in their results announcement that started the selling looked quite good to me but I've learnt over the years that Bryce Edwards SFAQL rule is worth following so I sold with everyone else. The rule is, if the market is selling news on a stock on volume, "sell first, ask questions later". You'll get caught out selling a stock that turns around and rebounds hard occasionally but more often than not you'll be much better off getting out. In this case there's been some 40% wiped off the value of the company which is a 70% gain to be made on the way back up
I just noticed I haven't changed my disclosure, it's not held
