Why the CAC 40’s Record High Signals a Luxury‑Led Rally

The benchmark index rose 1.3% to 8,421, breaking its previous peak. While broad‑based gains lifted most constituents, the heavyweight drivers were unmistakably luxury‑focused. Hermès, LVMH, Kering and L’Oréal collectively added more than 5% to the index’s momentum, underscoring a sector‑wide rebound after a year of mixed sentiment.

From a macro perspective, the French economy is benefitting from a stabilising euro, modest inflation, and a consumer‑confidence upswing in the Eurozone. Those macro back‑stops are amplifying the premium‑goods narrative, turning discretionary spending into a reliable earnings engine.

Hermès Beats Forecasts: What the Birkin Boom Means for Investors

Hermès surged 2.6% to a near one‑month high after reporting Q4 revenue that topped analysts’ expectations. The catalyst? Unrelenting demand for the iconic Birkin bag, which remains a status symbol with a waiting list that stretches years.

Key takeaways for investors:

• Revenue Quality: The company’s top‑line growth was driven by higher average selling prices rather than volume, a sign of pricing power.
• Margin Resilience: Gross margins improved by 30 basis points, reflecting efficient supply‑chain management.
• Supply‑Side Constraints: Limited production capacity creates scarcity, supporting price premiums.

In valuation terms, Hermès trades at a forward EV/EBITDA multiple of 18×, still premium to the broader consumer discretionary index (12×). The gap suggests the market is pricing in sustained brand‑centric growth.

EssilorLuxottica’s Paradox: Weak Profit Yet Explosive Stock Jump

EssilorLuxottica rallied 8.7% despite announcing a weaker full‑year 2025 profit. The paradox lies in the company’s Q4 revenue growth and an upbeat outlook for the optical‑technology segment.

Investors are focusing on two underlying themes:

• Vision‑Tech Tailwinds: The rise of premium eyewear and the rollout of AR‑compatible lenses are expected to add $1.2 bn of incremental revenue over the next three years.
• Geographic Diversification: Strong performance in emerging markets, particularly China and India, offsets slower growth in mature Europe.

From a fundamentals standpoint, the company’s price‑to‑earnings ratio compressed to 15×, still below the sector average of 18×, hinting at upside if profit margins recover.

Legrand’s Data‑Center Play: A Blueprint for Mid‑Cap Gains

Legrand climbed 3.6% to its highest level since November 2025 after raising its medium‑term profitability targets. The catalyst is a surge in data‑center‑related activity, as cloud providers expand infrastructure across Europe.

Key drivers:

• Infrastructure Spend: European data‑center capex is forecast to grow at a CAGR of 9% through 2028.
• Product Portfolio: Legrand’s power‑distribution and connectivity solutions are positioned as “plug‑and‑play” for hyperscale operators.
• Margin Expansion: Targeted EBITDA margin improvement of 150 basis points by 2027.

For mid‑cap investors, Legrand now trades at 14× forward EBITDA, offering a value tilt relative to the French mid‑cap average of 16×.

Historical Echoes: Past Luxury Cycles and What They Teach Us

The last time the CAC 40 was powered by luxury stocks was in 2018‑2019, when LVMH and Kering posted consecutive double‑digit revenue growth. That rally culminated in a 12% index gain before a corrective pull‑back driven by geopolitical tensions.

Lesson learned: luxury‑led uptrends tend to be strong but can be vulnerable to macro shocks. However, the underlying brand equity often sustains long‑term outperformance, as seen in the post‑2009 recovery where French luxury stocks outperformed the MSCI World index by an average of 4% per annum.

Investor Playbook: Bull vs. Bear Cases on French Luxury & Tech

Bull Case

• Continued Q4 revenue beat across Hermès, LVMH, and Kering fuels earnings momentum.
• EssilorLuxottica’s vision‑tech pipeline accelerates, unlocking new high‑margin segments.
• Legrand’s data‑center exposure captures the €200 bn European cloud‑infrastructure spend.
• EUR‑denominated assets benefit from a stable euro and modest rate‑cut expectations.

Bear Case

• Consumer sentiment stalls if inflation resurges, hitting discretionary spend.
• Supply‑chain disruptions could erode Hermès’ scarcity model.
• Regulatory scrutiny on data‑center energy usage could increase operating costs for Legrand.
• Global equity volatility could trigger a rotation out of high‑beta luxury names.

Strategic takeaways: consider overweighting premium‑luxury exposure with a disciplined stop‑loss, while using Legrand as a growth‑oriented mid‑cap hedge. Diversify across the luxury‑tech nexus to capture both margin expansion and secular demand trends.
