Can't find anything in the press. IMO it could be the strength of the A$, reducing their input costs.
MCP is moving in parallel with PBG.
It could also be the merger GUD / Breville bring more interest back to branded companies. PBG has strong brands, exposure to the home market and industrial workware.
PBG is still only a P/E of 8.4 and P/B of less than one. The market will re-rate further imo. A price of over $2 would be more reasonable.
