Well as across Europe, the automotive sector is up an average of 1.5% after a turbulent period. It has been essentially flat since the beginning of the year. Iveco up nearly 3 percent today, Stellantis up 1.6 percent.
In contrast, banks are flat, with the outlook for monetary easing not favoring the sector; Bper recovers its initial decline and rises to just above par.
Lively Tim (+2.2%). Mef and Retelit have asked for a two-day postponement of the deadline to submit a bid for Sparkle. Intermonte does not rule out that the current, non-binding 700 million offer could be improved.
Quiet Eni and Enel, down go Buzzi and Recordati.

Loses more than 5% Dovalue at the end of the capital increase, in light Lazio (+1.9%), which won in Amsterdam against Aiax in the Europa League.
