The Week Ahead

This week’s news flow included an expansion of Avantor’s RIM single-use portfolio across APAC, alongside broader commentary on capacity optimisation and guidance upgrades in manufacturing and resources. Next week’s macro calendar offers a packed run of US data — the Richmond Fed composite index on Tuesday, EIA crude inventory reports on Wednesday, and initial jobless claims plus new home sales on Thursday. For a mid-tail cyclical name like Avantor, those prints could shape the tone around valuation elasticity.
