Japan’s Nikkei stock index jumped nearly 5% on Monday to a new record close while shares in France fell back after its prime minister resigned less than a month after taking office.
The CAC 40 in Paris dropped 1.8% to 7,937.43 in early trading.
France's new prime minister, Sébastien Lecornu, resigned just a day after he named his government, drawing a backlash across the political spectrum for his choice of ministers. French politics have been in disarray since President Emmanuel Macron called snap elections last year that produced a deeply fragmented legislature.
In Germany, the DAX was little changed at 24,388.31 and Britain's FTSE 100 fell 0.2% to 9,473.51.
The future for the S&P 500 gained 0.3%. On Friday, it hit yet another record high close, as did the Dow Jones Industrial Average. Its future contract was up 0.1% early Monday.
While Tokyo's Nikkei 225 soared, gaining 4.8% to 47,944.76, the Japanese yen weakened after the ruling Liberal Democratic Party chose ultra-conservative lawmaker Sanae Takaichi as its leader and likely Japan's first woman prime minister.
In intraday trading the Nikkei climbed as high as 48,150.04.
Takaichi, 64, was an ally of the late Prime Minister Shinzo Abe and is expected to carry on with his market-friendly policies since she backed his traditionalist vision for the country. She is almost certain to become prime minister because the LDP has the most seats in the lower house, although not a majority. It chooses the prime minister, and opposition groups are splintered.
The yen slipped against the U.S. dollar on expectations that Takaichi will boost spending, likely adding to inflationary pressures. The dollar rose to 150.31 Japanese yen from 149.33 yen. The euro slipped to $1.1674 from $1.1730.
Investors, especially non-Japanese ones, were pleased, said Neil Newman, head of strategy at Astris Advisory Japan.
“Obviously, investors like what she has been saying and certainly today judging by the number of stocks that moved and which stocks moved, it seems like pretty much led by foreigners so far,” Newman said.
Defense-related shares got a big boost, given Takaichi's hawkish stance. Stock in Kawasaki Heavy Industries leaped 9.2% and Mitsubishi Heavy Industries soared 11.1%.
An unconfirmed report that U.S. President Donald Trump might be considering ways to reduce the cost of his higher tariffs on auto parts and other materials for U.S. manufacturers helped automakers' share prices. Toyota Motor Corp.'s shares jumped 4.9% in Tokyo and Honda Motor Co. gained 4.1%.
