FTSE 100 Gains: A Blessing from Cyclical Index Composition 
UK100
The UK stock exchange's regular trading session on Tuesday afternoon, May 26, 2026, showcased a remarkably robust macroeconomic deconstruction.
While mainland European markets were extremely cautious (the STOXX 600 moved sideways due to concerns about a fighter jet attack in the Strait of Hormuz), London's FTSE 100 index surged more than 0.5%.
This powerful acceleration was a combination of catch-up trades following yesterday's UK public holiday, as well as the FTSE 100 index composition, which mechanically benefited from rising Brent crude oil prices due to the latest military escalation.
----------------------------------------------------------------------------------------------
✅ Defense & Pharmaceutical Stocks Surge
- Strait of Hormuz Tensions Effect (Week 12): The US Central Command's report of a US-Israeli fighter jet airstrike on an Iranian logistics ship immediately sent capital into defense stocks. Babcock International surged 2.1%, followed by Rolls-Royce (up 1%), and BAE Systems (up 0.5%).
- Pharmaceutical Stocks Defensive Anchor: Global healthcare giants also supported the index, with AstraZeneca and GSK both rising in the 0.5%-1% range.
