SEMAPA Shares Surge 15% by Midday, Boosted by Subsidiary Sale
On Friday, December 19, 2025, the shares of Portuguese conglomerate SEMAPA climbed 15.29% to €19.60 by midday. This significant increase, triggered by the sale of its cement subsidiary Secil to Cementos Molins for €1.4 billion, along with trading volumes representing 0.32% of the capital, pushed the stock to a new annual high and extended an upward trend that started several weeks ago.
Midday Market Update
By midday this Friday, SEMAPA's stock recorded a gain of 15.29% reaching €19.60, up from a close of €17.00 the previous day. This rebound marks a significant acceleration of an already well-established trend. Over the past week, the stock has gained 13.95%, and over three months, it has increased by 9.01%. On an annual basis, the rise peaks at 44.33%, reflecting renewed investor confidence in this diversified Portuguese group active in pulp, cement, and environmental services. Trading volumes remain moderate at 0.32% of the capital, but are sufficient to validate this upward movement. The stock has thus broken through key technical resistances and is now trading above its moving averages, signaling a market regime change for this small-cap stock listed on Euronext Lisbon.
Technical Analysis Insights
Technical analysis confirms the strengthening of the positive momentum observed in SEMAPA. The Relative Strength Index (RSI) stands at 53, in the neutral zone, suggesting that the stock still has room to grow before reaching an overbought situation. This indicator, which measures the relative strength of a trend, indicates that the current upward movement is not yet exhausted and could continue. Additionally, the MACD histogram shows a positive value of 0.05, illustrating the start of a bullish reversal after a consolidation phase. The MACD line (-0.11) remains below its signal line (-0.16), but the positive divergence between the two suggests a possible convergence soon, which would strengthen the buy signal. The stock is now clearly trading above its 50-day (€17.46) and 200-day (€17.66) moving averages, confirming the solidity of the underlying movement.
SEMAPA's Favorable Dynamics
SEMAPA, a Portuguese holding company with diversified activities, has been experiencing favorable dynamics since the beginning of the year. In the absence of an immediate identifiable catalyst this Friday, this surge could be explained by a technical catch-up and a gradual revaluation of the case by investors. The group, which published its third-quarter 2025 results at the end of October, then reported consolidated revenue of €2.147 billion over nine months, slightly up from the previous year. The conglomerate, which employs nearly 7,815 people, continues its strategy of diversification and investments in new segments, notably through the acquisition of Imedexa in Spain for €148 million. This strategy of external growth and the profitability prospects of its subsidiaries Navigator and Secil seem to attract investors, who support the stock towards new highs. With a beta of 0.02, SEMAPA stands out for its low correlation with the markets, thus offering a defensive profile appreciated in times of uncertainty.
