Amcor shares fell about 11.7% over the trailing 30 days, slipping from roughly $47.45 in mid-August to $41.90 by mid-September. The decline followed a strong earnings-driven rally, suggesting profit-taking and a rotation out of packaging names after an extended run-up. A JPMorgan downgrade to Neutral, the September 4 ex-dividend date, and renewed macro and cost-inflation concerns all weighed on sentiment. $SW $AVY $GEF $CCK $IP $SLGN $BALL $PKG
