Europe's STOXX 600 hits all-time high

LONDON, June 15 (Reuters) - Europe's STOXX 600 hit an all-time high on Monday after the United States and Iran reached a preliminary pact to end their war and reopen the Strait of Hormuz, surpassing its previous record hit just before the start of the conflict. 

Many other major indexes in the U.S. and Asia are already trading well above their pre-war peaks, helped by surging technology stocks, which make up a smaller share of the European benchmark, and, in the case of the U.S. investors' view that it was less exposed economically to the war in Iran. 

The STOXX 600 was last up 0.9% at 638.53 points.
