What matters now

AI capex faces FCF scrutiny, yet hyperscalers are locking in $500B+ supply deals through 2030. The memory cycle favors SK Hynix over Samsung amid HBM constraints. Geopolitical strikes on Saudi and Russian refineries threaten a stagflationary oil shock. US margin debt hits a record $1.5T.

Main narratives

day change
01

Hyperscaler FCF concerns clash with 2030 capacity lock-ins

Alphabet's negative free cash flow and rising capital expenditures are sparking fears of margin compression as technology companies shift to an asset-heavy model. However, multi-year agreements exceeding $500 billion between Nvidia, SK Hynix, and Broadcom suggest hyperscalers are prioritizing long-term capacity over near-term ROI fears.

02

Refinery strikes and Red Sea blockades tighten global oil supply

Houthi ballistic missile strikes on Saudi Aramco's Jazan refinery and Ukrainian drone attacks on Russian energy infrastructure are creating unprecedented supply disruptions. Global inventories of crude and refined products are at multi-year lows, leaving minimal buffer for further geopolitical shocks.

03

SK Hynix favored over Samsung as HBM acts as advanced logic

Foreign futures positioning and analyst upgrades show a clear preference for SK Hynix over Samsung, driven by SK's High Bandwidth Memory dominance and favorable long-term agreement structures. While NAND pricing growth is slowing, structural AI data center demand for high-capacity SSDs remains robust.
