FTSE 100 Nears Record High, But Six Blue-Chip Stocks Show Double-Digit Discounts

The UK's FTSE 100 index is trading within 2% of its all-time high, buoyed by stronger-than-expected domestic economic data. However, a new analysis from Investing.com indicates that at least six of its blue-chip constituents are trading at double-digit discounts to their calculated fair value, presenting a notable divergence between the broad market and individual stock valuations.

Index Performance Masks Underlying Value

The FTSE 100 index reached 10,713 on Friday, just shy of its all-time high of 10,935, according to the source. The move was supported by a UK retail sales report showing +1.0% growth in June, far exceeding the -0.3% consensus estimate. This has pushed the index to a +17.2% gain over the past 12 months.

Despite the index's strong performance, the market backdrop includes potential headwinds. A stronger pound can negatively impact the reported earnings of the index's many multinational firms, which generate most of their revenue in foreign currencies. Furthermore, new U.S. tariffs of 10–12.5% on dozens of trading partners took effect, adding a layer of geopolitical uncertainty.

A Closer Look at Undervalued Stocks

Analysis based on quantitative models from Investing.com highlights six major FTSE 100 companies with significant upside potential relative to their current share prices. The report identifies pharmaceutical giant GSK as having the largest valuation gap in the large-cap index.

The companies and their estimated fair value upside are:

• GSK (GSK): +52.4% upside
• London Stock Exchange Group (LSEG): +30.2% upside
• Diageo (DGE): +27.8% upside
• BP (BP.): +18.8% upside
• RELX (REL): +17.1% upside
• AstraZeneca (AZN): +10.1% upside

Key Company Highlights

Among the highlighted stocks, GSK stands out with a potential +52.4% upside, trading at a low 10.4x forward P/E ratio despite steady revenue growth. The source notes that litigation concerns have been a primary overhang for the stock.

Spirits maker Diageo is presented as a contrarian opportunity. After a period of revenue decline, its shares offer a +27.8% fair value upside and a 4.1% dividend yield, with the selloff seen as potentially overdone. In the energy sector, BP trades at an 8.1x forward P/E and offers a 10.0% free cash flow yield, representing a deep value play in a high-priced market, though it remains exposed to oil price volatility.
