Sopra Steria Stock Falls Nearly 11% Over One Month

A Decline Reflecting Difficult Monthly Momentum, With Support at €156.10

Sopra Steria lost 1.97% to €159.50 in trading, a decline in line with that of the SBF 120 (−1.33%) and the CAC 40 (−1.29%), both pressured by tensions on French sovereign rates. The ten-year OAT is approaching its highest level since 2008, rising to 4.86% on Thursday, while the spread with the German Bund reached its highest level since 2012 at 1.30 percentage points. Over one month, the stock has declined 10.74%, which puts into perspective the quarterly rebound of 14.26% posted over three months.

The nearest support at €156.10 now represents a gap of just under 2% below the current price. If this level were to be tested, it would be an area already monitored during the bearish phases of summer.

Short Positions Declining, Contained Valuation and Confirmed Guidance

Regarding net short positions, speculative pressure has eased: 2.89% of capital is sold short according to the declarations reviewed, compared to 3.47% thirty days ago, a decline of 0.58 percentage points. This 0.58 percentage point decline over one month suggests that some investors have reduced their bearish exposure, without reversing the trend. The stock is also trading at just under nine times the expected earnings for the current fiscal year according to the consensus of analysts surveyed, a modest level for the sector. As a reminder, during the publication of first-half 2026 results (July 29, 2026), management raised its annual organic growth target to +2.0%/+2.5%, driven notably by aerospace and defense-security-space. The analyst consensus incorporates an earnings per share growth of approximately 11% year-over-year, which, combined with the easing of short positions, tempers today's selling pressure.
