The pan-European STOXX 600 index recorded its best day in a month on Tuesday, joining a global rally after the prospect of historic monetary and fiscal stimulus revived hopes of an economic rebound from the COVID-19 pandemic.

The index rose 2.9%, recovering some of the losses of recent sessions when grim economic forecasts and a resurgence in infections in the United States and China encouraged investors to play safe.

German and Italian shares outperformed their European peers, with cyclical sectors including travel, construction, banks <.SX7P> and autos gaining 3-4%.

Aggressive global stimulus has helped to power a rebound in European equity markets since a coronavirus-fuelled crash in March, with the STOXX 600 index now only about 16% below its February record high.

Europe's volatility index <.V2TX> retreated for a second straight day and was on track for its biggest daily percentage fall in a month.

Travel and leisure stocks rose 1.7%, with the British cinema operator Cineworld rising 1% after saying it expected all of its theatres to reopen by July.

The German airline Lufthansa was 2.5% higher after saying late on Monday it was seeking agreements with worker representatives by June 22 on how to make cuts equivalent to 22,000 full-time positions.

The German online fashion retailer Zalando fell 4.2% after Swedish investment firm Kinnevik AB sold a stake.

Equipment rental giant Ashtead Group soared 9.6% to a record high after proposing a dividend at a time when most firms have scrapped payouts to shore up cash reserves to ride out the economic slump.
