The S&P/TSX Composite edged up to above the 29,930 mark on Wednesday, following a sharp downturn the previous session as a rebound in energy names offset continued pressure in miners amid renewed trade and geopolitical uncertainty. Canadian Natural Resources, Suncor, Imperial Oil and Cenovus led the advance, each up roughly 0.5 to 0.8% after oil prices recovered when the White House said the planned summit between US President Donald Trump and Russian President Vladimir Putin was postponed following Moscow’s refusal to agree to a Ukraine ceasefire, a development that refocused markets on possible sanctions and supply disruption. Miners were mixed as bullion extended a sharp pullback. Ambiguity over whether Trump will meet Chinese President Xi Jinping after his comments that the meeting "maybe won’t happen" kept risk premia elevated and trading cautious.
