With the ongoing war in Ukraine, continuing conflict in the Middle East, and a reshaping of the global framework underway since Donald Trump came to office, defence stocks have been hot property in the world of investing. While Australian investors don’t have that many options when investing locally, an exception is ship builder Austal (ASX:ASB).  Austal has been a long-term holding for IML’s small and mid cap funds, which have seen its share price triple since the start of 2024. However IML portfolio manager Lucas Goode thinks there could still be plenty of upside for Austal in years to come.
