What L’Oréal’s Stock-Market Coronation Really Says About LVMH

Some shifts of power happen with a cannon blast. Others happen by the slimmest of margins. The one that has just taken place on the Paris stock exchange belongs to the latter category. No bombastic statement, no press conference, no guard of honor. Just a column of figures that, by the close of trading on Tuesday, September 15, 2026, had finally tipped against the luxury giant.

L'Oréal ended the session with a market capitalization of €202.9 billion, ahead of LVMH at €201.4 billion, following a 37% decline in the LVMH share price since January.

For the first time since 2017, a company that is not a pure-play luxury group has taken the top spot on the Paris market at the close of a trading session, according to Reuters.

The battle had been brewing for weeks. As early as September 9, L'Oréal had already edged past LVMH, with a negligible €1.2 billion lead over a combined market capitalization of more than €400 billion. The following day, that lead had narrowed to just €0.31 billion — little more than the margin of error of a routine stock-market swing.

One stock would move ahead of the other, only for the positions to reverse again, in a succession of trading sessions where every percentage point mattered. On September 11, LVMH was still back in front during the morning session before being caught again. That alone shows how fragile the ranking is.

As an analysis by France Épargne aptly points out, a gap of this magnitude — less than 0.2% of the two groups' combined value — can be wiped out in a single trading session. The snapshot captured at the close on any given day is hardly something set in stone.

But the fragility of the symbol does not diminish its significance. Because L'Oréal did not exactly surge ahead: shares in the Clichy-based group have risen by only around 3.6% to 5% since January 1. It is LVMH that has collapsed — down 35% for the year, bringing the stock to its lowest levels since October 2020. The change in rank, then, was not the result of a victory.

This crossover did not come out of nowhere. As early as April 2026, equity strategists were already openly discussing in the financial press the possibility that L'Oréal might one day overtake LVMH at the top of the Paris market. At the time, however, the gap still appeared comfortable: Thierry Gautier, CEO of GSD Gestion, told BFM Bourse that LVMH still had a lead of around €30 billion over its rival — a safety cushion equivalent to roughly 15 percentage points that would need to be made up. At that stage, he believed the luxury group would hold on to its crown. Five months later, that cushion had completely evaporated.
