Carbios stock surges 12% in a single session following announcement
The Clermont-Ferrand biotechnology company crosses an industrial milestone with the validation of a production line for recycled polyester t-shirts, from textile waste to finished garment. This intraday jump occurs in a slightly positive market context, with the CAC 40 gaining 0.3% and the SBF 120 advancing 0.34%.
A textile recycling press release propels the stock above its 20-day moving average
Carbios surges 12.18% in early afternoon, to €6.08, following the publication this morning of a press release validating an integrated European textile chain. Within the Fiber-to-Fiber Consortium, the company has produced recycled polyester t-shirts from complex textile waste, in partnership with Patagonia, PUMA and Salomon. The operation is based on the enzymatic biorecycling process for PET, applied this time to fiber blends deemed difficult to treat.
This concrete result on a complete chain, from waste to finished garment, marks a notable industrial milestone for the technology developed in Clermont-Ferrand. From a technical perspective, the stock clearly moves back above its 20-day moving average at €5.60, with a gap of +8.57%, whereas it remained below it in recent weeks. The RSI at 44 remains in neutral territory, which tempers any overbought reading despite the magnitude of the movement.
A resistance level at €6.61 in sight, backed by solid cash position published late last week
After this rebound, the stock approaches its resistance level at €6.61, representing an approximately 8.7% gap from the current price. Before reaching the €6.61 resistance, the stock must first break through the 50-day moving average at €6.26, from which it remains slightly below (-2.88%), which conditions the credibility of the upward momentum. Over the longer term, the 200-day moving average at €7.85 remains distant, with a gap of -22.55%, highlighting the depth of the decline accumulated over one year (-30%).
Today's rebound partially eases the pressure on the stock, but only mitigates a fraction of the annual decline. To provide context for this day, recall that the first half 2026 results published on September 24 had highlighted a 19% reduction in operating expenses year-over-year and cash reserves of 48 million euros, two elements that support the company's operational capacity while awaiting an industrial ramp-up. The 50-day moving average at €6.26 constitutes the next technical test of the session, before the €6.61 resistance level.
