The star CAC 40 index advanced 91.03 points to 6,564.34 points around 10:05 a.m.
On Friday, it ended the session down 1.52%, weighed down by the first trends in the American markets.
The drop over the week was slight (-0.47%), but over the year, the CAC 40 experienced its biggest drop since 2018, with a decline of 9.50%.
Friday's decline had been accentuated by Wall Street's difficult start to the session, but "the US indices recovered strongly during the last hour of trading on Friday", ending close to balance, pointed out Jochen Stanzl, analyst at CMC Markets.
On Monday, Wall Street will remain closed, as will Tokyo, Hong Kong and even London.
