Weak consumption, $90 oil and higher yields revive the stagflation trade.

Core view

Bad data is no longer an automatic rate-relief trade.

The mix is less friendly: consumption is weakening, but oil and long yields are rising. That raises revenue risk and keeps discount rates high. Within AI, investors are rewarding physical bottlenecks such as memory and equipment while scrutinizing platform free cash flow.
