Alten's Stock Plummets 46% in One Year, Hitting a 10-Year Low

This Thursday, Alten's stock hit a new 10-year low at 51.50 euros, down 2.55% from the previous day. The engineering and technology consulting group is experiencing an accelerated decline, with a loss of nearly 28% over three months and 46% over one year. This downturn occurs in a context of generalized weakness in the Paris market, with the CAC 40 down 0.87% during the session.


Alten's Stock Plummets 46% in One Year, Hitting a 10-Year Low

Technical Indicators Highlight Strong Downward Momentum

During the session, Alten's stock breached the 52.05 euros mark, its previous low from 2016, to set a new 10-year low at 51.50 euros. Crossing below the 52.85 euros support level is a negative signal technically. The stock is now significantly below its 50 and 200-day moving averages, set at 64.92 and 69.05 euros respectively, indicating a considerable gap between the current price and its medium-long term trend. The RSI, an indicator measuring the speed and magnitude of price changes, stands at 28, signaling an oversold zone. Theoretically, this level indicates that selling pressure is particularly pronounced, although it does not necessarily predict an imminent reversal. The stock is also touching the lower Bollinger band (51.68 euros), confirming the intensity of the ongoing downward movement. Over the week, Alten has lost nearly 8.7%, in a trend that has been decidedly downward for several months.

Alten's weakness is not entirely specific to the company. Among comparable sector values, Capgemini has lost 1.42% in Thursday's session, confirming a climate of distrust towards digital services and engineering companies listed in Paris. The SBF 120 index is also down by 0.92%, reflecting the unfavorable tone across the board. Alten's next financial appointment is set for April 28, the date for the publication of the first quarter 2026 revenue. This milestone will be crucial in assessing the commercial trajectory of the group, as the stock has lost nearly half its value in twelve months. The general assembly is scheduled for June 18. Until then, operators will have few new elements to adjust their assessment of the situation, leaving the stock exposed to movements in the flow on the segment of European midcap technology stocks.
