Bureau Veritas and Eurofins Sink on Stock Market: CAC 40 Dragged Down Midday

A Session Marked by Heavy Individual Penalties

Mid-session, it's not so much the general market trend that's striking, but the extent of certain declines. The CAC 40 is falling moderately, but the dispersion within the index is remarkable: out of 40 stocks, 25 are down, 14 manage to rise, and only one remains stable. The atmosphere is heavy, following an already negative session on Wall Street the previous day: the Dow Jones, S&P 500, and Nasdaq all closed Tuesday evening down nearly 0.6%. This Wednesday morning, European markets are following suit, with the DAX retreating 0.35% during the session in Frankfurt, while the STOXX 600 drops 0.18%. In Asia, the Hang Seng ended the day with a significant decline of 1.22%. Only the Nikkei 225 stood out, closing up 0.40% in Tokyo.

Danone and Energy Companies Lead the Few Survivors

Danone emerges as the largest gainer on the CAC 40 by midday, rising 2.95% to 68.38 euros. Shares of the food industry giant are moving against the general trend, as defensive stocks are attracting more investors during uncertain sessions.

The energy sector also shows notable resilience. TotalEnergies rises 1.28% to 75.99 euros, while Engie climbs 1% to 28.25 euros. STMicroelectronics, the only tech stock standing out, gains 1.52% to 38.18 euros.

In the retail sector, Carrefour is up 0.96% to 16.87 euros. The group announced the sale of its minority stake in CarrefourSA in Turkey, an international asset portfolio restructuring operation.

Bureau Veritas and Eurofins in freefall, luxury under pressure

But it's the bottom of the table that is drawing all the attention this morning. Bureau Veritas plummets by 12.06% to 25 euros after the publication of its first-quarter 2026 results, a rare and severe drop for this inspection and certification specialist. The stock is by far the worst performer on the index.

Eurofins Scientific follows a similar path, diving 10.32% to 62.20 euros. The bio-analytical services laboratory faces an equally harsh penalty, also following a disappointing release. These two double-digit declines, unusual within the CAC 40, weigh heavily on the Paris market sentiment.

The luxury sector adds to the prevailing gloom. LVMH drops 1.86% to 476.95 euros, while EssilorLuxottica loses 1.94% to 202.70 euros. Safran, in the aerospace sector, falls 2.97% to 274 euros, rounding out a series of declines that span very different sectors.
