Nearly 54% increase in three months: Alten stock extends its rally
The engineering consulting specialist continues its rebound in early afternoon trading, in a slightly positive CAC 40. The stock is evolving at unprecedented levels since the start of the year, far from its moving averages, just days away from an activity update.
An advance widening across all moving averages of the stock
The Alten stock gains 2.9% to €86.85, following a 12% gain over seven days and 23.6% over one month. On October 13, it broke through its €82 resistance level, which has since become support, and is now trading 11.5% above its 20-day moving average and nearly 33% above its 200-day moving average. The RSI at 68 remains below the overbought zone, but the next round level is at €90, a benchmark situated above the current price. This session places Alten among the strongest gainers of the SBF 120, which is up 0.36%.
An activity update expected on October 21 after a quarter with over 50% gains
The stock has gained nearly 54% in three months, driven by the recovery in organic growth of its half-year results published on September 25, with margin and free cash-flow expanding. The group will detail the evolution of its business over the first nine months of 2026 on October 21. On the capital side, Alten bought back €53 million worth of shares over twelve months, representing 1.7% of its market capitalization, according to its latest declaration from September 23. The group is headed by Simon Azoulay, chairman of the board of directors, and is headquartered in Boulogne-Billancourt.
