FTSE 100 Hits Record High; AstraZeneca Regains Top Spot
Introduction
On October 1, 2025, the UK’s FTSE 100 index reached a historic milestone, closing at a record high of 9,446 points. This achievement was propelled by a significant surge in pharmaceutical stocks, notably AstraZeneca, which regained its position as the most valuable company on the London Stock Exchange. The rally occurred despite global economic uncertainties, including the onset of a U.S. government shutdown and weaker-than-expected U.S. labor market data.
AstraZeneca’s Market Performance
AstraZeneca’s stock price soared by over 11% on October 1, closing at £124.36, marking a new 52-week high. This surge lifted the company’s market capitalization to approximately £192 billion, surpassing HSBC to become the UK’s most valuable publicly traded company (MarketWatch). The rally was attributed to easing concerns over potential U.S. tariffs on branded drugs and investor optimism surrounding the company’s growth prospects.
Factors Contributing to the FTSE 100’s Record High
Several factors contributed to the FTSE 100’s ascent to a new record:
- Pharmaceutical Sector Rally: In addition to AstraZeneca, other pharmaceutical companies such as GSK and Hikma Pharmaceuticals experienced significant gains, with stock prices rising by 6.1% and 5.7%, respectively.
- Global Economic Factors: Despite global economic uncertainties, including the U.S. government shutdown and weaker-than-expected U.S. labor market data, investor confidence remained robust, buoyed by expectations of potential interest rate cuts by the Federal Reserve (The Guardian).
- Sectoral Strength: The FTSE 100’s performance was also supported by strong performances in sectors such as defense, mining, and banking, reflecting broad-based investor confidence in UK-listed companies.
AstraZeneca’s Strategic Moves
AstraZeneca’s market resurgence was further bolstered by strategic decisions aimed at enhancing its global presence:
- U.S. Listing Enhancement: The company announced plans to upgrade its U.S. listing by directly listing its ordinary shares on the New York Stock Exchange, replacing its American Depositary Receipts (ADRs). This move aims to attract more U.S. institutional and retail investors and enhance trading liquidity (Financial Times).
- Commitment to U.S. Market: AstraZeneca reaffirmed its commitment to the U.S. market, which accounts for nearly half of its revenue and is expected to reach 50% by 2030. The company plans to invest $50 billion in U.S. manufacturing and research and development, aligning with political pressures encouraging pharmaceutical investment in the U.S. (Financial Times).
