If we assume current market cap of $918m. Let's consider P/E: If HY reports $15m earnings. FY19 would be $35m accounting for a 30% improvement in H2. This is worst case IMO. We should see a drop to $6 should this result eventuate as P/E needs to be around 20 for the one dimensional BAL. If HY reports $26m earnings. FY19 would be $46m to $60m which would see the SP hold or increase to up to $10.
Either way, expect the SP between $6 and $10, hence an 87.5% chance of profiting on a short at $9.50.
