I feel like the Management are competent and were being open regarding unforeseen negatives early. This should manage expectations of the final figures for H1FY20. The market has now priced this in as far as holders go so IMHO the shorters will not have much more ammunition tomorrow. Short sellers may settle in for the long haul to the end of FY20 but the briefing noted that the "cash consumption for the next half will be at a much reduced rate" so if we add the top line growth and reduced spend then the FY20 results should be pretty strong.
That said, the market is not sensible and some hedge funds have a lot of money to pressure the SP with so I will wait and see. I have topped up on the recent weakness so a rise will be useful. If it goes lower then I will find some more to dilute more. Please DYOR and keep in mind I may be very wrong.
