The Lisbon stock exchange closed today near the so-called "waterline," a term used in the financial market to designate a critical support level. The PSI index closed with a gain of 0.07%, settling at 9,437.18 points.
The main support for the Portuguese index's gains came from Galp Energia, which recorded a gain of more than 2%. This positive performance by the oil company was decisive in preventing the PSI from closing in negative territory.
The trading session in Lisbon took place in a context of some stability, with the index fluctuating around important technical levels. The "waterline" represents a level that, when threatened, can trigger additional selling by investors.
