Nanobiotix share declines 1% but posts +22% on the week

The Parisian oncological nanomedicine biotech slips slightly in mid-morning trading, in a Paris market clearly oriented downward. This modest pullback comes after a marked weekly rebound, which brought the stock back toward its short-term technical benchmarks.


Nanobiotix share declines 1% but posts +22% on the week

A limited decline that contrasts with a SBF 120 in sharp retreat

Nanobiotix loses 0.83% to €23.86, while the SBF 120 drops 1.47% and the CAC 40 falls 1.51%. The stock thus ranks in the middle of the broader index, significantly less affected than the market. Over the week, it still shows a gain of nearly 22%, but it remains down 19.55% over one month and 28.56% over three months.

Sector comparables do not send a homogeneous signal: Sanofi declines 0.87%, with -1.96% over one month, while Eurofins Scientific advances 1.41% and gains 3.9% over the same period. The Paris market is moreover evolving in a context of elevated French rates, with the 10-year OAT at 4.99% according to the Banque de France survey of October 21.

A 20-day moving average reclaimed, a 50-day moving average still 18% above the price

The week's rebound brought the price to 4.19% above its 20-day MA (€22.90), a level that the stock had lost during the month's slide. The 50-day MA, at €29.06, meanwhile remains nearly 18% above the price, and the 200-day MA at €28.86 in the same range: the underlying trend remains downward. The RSI at 48 is neutral, after falling to 22.8 on October 19.

The company had published on September 24 its financial update for the first half of 2026, with €110.9 million in cash, an amount that would allow it to finance its operations through 2029. On levels, support at €18.85 and resistance at €31.30 bound the current trading zone.
