Europe's main equity benchmark finished slightly higher Monday, as gains for energy and mining stocks offset drops by Italian banks and U.K. manufacturer Essentra PLC. Italy is holding a constitutional referendum on Dec. 4, and a defeat for Prime Minister Mateo Renzi's Democratic Party would make it more difficult for the government to pass reforms, potentially prompting Renzi to dissolve his government.

U.S. stocks closed higher at fresh records Monday, aided by a jump in oil prices and a pullback in the dollar, giving the Dow industrials, S&P 500 and Nasdaq their third simultaneous all-time closing highs this year. The last time all three indexes closed at record highs at the same time was two sessions back in mid-August, and before then had not occurred since 1999.

Asian shares were broadly higher early Tuesday, with the Australian market rising to a one-month high, as oil prices rallied on expectations that key oil-producing countries will agree to a deal to slash production.
