“The phase of multi-month increases on the Warsaw Stock Exchange has stopped. In the coming sessions, and perhaps even weeks, a downward correction should be expected. In the case of WIG20, this may mean going even below the barrier of 3,000 points,” said Przemysław Smoliński, analyst at BM PKO BP.
Energy and construction under greater pressure
The energy and construction sectors took the hardest supply hit. Index WIG-Energy dropped by 4.3 percent, and WIG-Budownictwo lost 3.72 percent. PGE shares fell by 5.99%.
