What it means
The U.S. decision to halt Iranian oil sales adds modest incremental supply tightness beyond what prior signals already captured, while a Samsung earnings disappointment has historically been associated with near-term sector-wide pressure on chip stocks. The oil move is partially already reflected in prior coverage of Hormuz supply risk, so the new incremental signal is smaller than it might appear in isolation.
