Nanobiotix stock among the strongest gainers of the SBF 120 after +34% in one week

A week of rebound that only partially offsets the monthly decline

The stock is trading at €26.50 and gaining 2.24% during the session, while the SBF 120 is down 0.72%. It ranks among the strongest gains in the index. Over the week, the gain reaches 34.25%, but it only offsets the 12.25% decline recorded over one month, and the 23.81% decline over three months.

The latest opinion published on the security, the small decline from the previous day, already came after this weekly recovery. Nanobiotix is a company listed on two markets: the ordinary share in Paris, eligible for PEA, and the ADS on Nasdaq, at a ratio of one ADS per share. The Nasdaq closed Thursday down 1.81%, a movement that could partly carry over to the Paris opening the next day.

Above the 20-day MA, below the 50-day and 200-day MAs that cap the rebound

In terms of price reference points, the stock is trading above its 20-day MA (€22.87, a gap of 15.87%), which it reclaimed after the month's decline. It remains, however, below the 50-day MA (€28.97) and the 200-day MA (€28.92), both approximately 8.5% above the current price and close to each other. The RSI at 57 is neutral: the rebound has not pushed the indicator into overbought territory.

On the fundamentals side, the company indicated when publishing H1 2026 results (September 24, 2026) that it had €110.9 million in cash, enough to finance its operations until 2029. The zone between €28.90 and €29.00, where the two long-term moving averages converge, is the next level the stock encounters if the rebound continues.
