Global shares rose on Wednesday, powered by a rise in technology stocks after U.S. President Donald Trump announced mammoth spending plans for artificial intelligence infrastructure, while the dollar sagged to a two-week low as tariffs were delayed.

Global shares showed mixed reactions to Trump's inauguration, with European indexes slightly up and Asian markets varied. Trump's delay in imposing new tariffs eased investor concerns, while energy prices dipped.
