Nanobiotix shares fall 2.5% and lose 12% in one week on the SBF 120

A 2.42% decline extending the weekly drop to -12.2%

Nanobiotix shares are down 2.42% at €26.62 at midday, while the SBF 120 falls 1.64% and the CAC 40 1.65%.

The stock is in the lower part of the broader index, without however belonging to its bottom tail, and has lost 12.2% over one week, after gaining nearly 19% over the month. This decline occurs in a session dominated by the correction in technology and artificial intelligence-related stocks, which hit Wall Street on Thursday and then Asian markets on Friday.

Sanofi and Eurofins Scientific, two healthcare stocks followed by the editorial team, fell 3.18% and 1.89% respectively this Friday. For Nanobiotix, the move remains moderate given the magnitude of the stock's recent price swings.

The stock remains above its 20-day moving average and below its 50-day moving average

The price of €26.62 is above the 20-day moving average, at €24.69 (a gap of +7.82%), but below the 50-day moving average, at €27.30 (a gap of -2.49%). This configuration reflects a short-term rebound that has not yet recovered the medium-term average.

The stock is also trading 9.70% below its 200-day moving average, at €29.48, and has lost 21.66% over three months.

When the H1 2026 results were published on September 24, the company indicated that its cash position of €110.9 million would allow it to finance its operations until 2029. Nanobiotix is listed in Paris and on the Nasdaq (ADS NBTX, at a 1-for-1 ratio), and Wall Street's close yesterday may therefore weigh on trading on the Paris exchange.
