AB Science shares jump nearly 8% and break through their 30-session high
The Paris-based biotech extends a rebound begun the previous day and ranks among the most dynamic stocks on the exchange at midday. The move brings it clearly back above its short-term moving averages, while the Paris market rises as a whole.
A rebound that exceeds a 30-session high and recovers 26% over the week
AB Science shares gain 7.9% to €0.67 in trading, following an already strong rise the previous day.
The stock price exceeds its 30-session high of €0.62, which has now become a support level, and is up 26.14% over the week. This performance places it above its 20-day moving average (MM20) at €0.55 (a gap of 21.64%) and its 50-day moving average (MM50) at €0.60, but still below its 200-day moving average (MM200) at €0.89 (a gap of 24.83%).
The RSI at 70 signals an overbought condition following this move. Over three months, the stock remains down 13.62%, and down 43.56% over one year. The next identified resistance is at €1.22.
A supportive market backdrop: the CAC 40 and SBF 120 gain about 0.7%
Among the stocks in the CAC All Shares index, AB Science ranks 7th among the largest gainers of the session, behind CFI, Foncière Volta, Française de l'Énergie, Chausseria and Crosswood. The move comes as the CAC 40 rises 0.73% and the SBF 120 gains 0.7%, while the VIX falls to 18.25.
On the fundamentals, the biotech had reported in October a net loss of €9 million for the first half of 2026, weighed down by a tax provision, with a reduced operating deficit. It had also disclosed at the end of 2025 cash of €10.2 million, in a context of refocusing its clinical programs. The €0.62 level now constitutes the technical reference to monitor over the coming sessions.
