The S&P/TSX Composite closed at 35,616.77 on Thursday, down 0.81 per cent, as a U.S. procurement threat hit Canadian engineering and infrastructure names hard enough that a surging oil price could not offset the damage.

The composite closed at 35,906.56 Wednesday, down 0.6% and in its fourth decline in five sessions, even as WTI crude climbed toward $100 on the tanker war.

The Dow fell 505 points Tuesday as bond markets kept repricing Friday's jobs report. Government of Canada yields moved with it, but the Canadian dollar strengthened anyway, and that split is the real story.

WTI is on its sixth straight higher session heading into the Tuesday open, U.S. futures are lower on Middle East and rate uncertainty, and the split puts Canadian energy names on the right side of both stories at once.

A blowout US payrolls print reverses a week of rate-cut optimism that had pushed gold toward $4,700 an ounce, and the swing reaches Canadian portfolios directly through TSX-listed precious metals miners.

Materials stocks led a rebound Wednesday even as the Iran conflict widened, and the index remains within striking distance of the record it set three weeks ago.

Canadian Natural Resources, Suncor and Cenovus climbed roughly 2% apiece as Brent extended its August rally, while Royal Bank, TD and the gold miners gave back ground on rising bond yields.

Oil-linked strength wasn't enough to save Monday's session, and futures point to more pressure Tuesday as the Strait of Hormuz conflict resumes and US rate-hike odds climb.

Friday's close at 36,553.92 marked a third straight down session from the August 25 record. Monday's session opens with oil up more than 3% on the weekend's Iran-US exchange, a direct reversal of what pulled energy names lower Friday.

The TSX fell for a second session Thursday, giving back part of Tuesday's record close as a rebound in oil revived inflation concerns even as most big banks beat estimates.

The TSX pulled back from Tuesday's record close as gold miners sold off, but three more bank beats this morning are keeping the index propped up against a backdrop of tariff retaliation and a hot U.S. inflation print.

Scotiabank's record quarter and BMO's 22% earnings growth carried the TSX composite to 36,957.63. Energy fell the same session as oil dropped for a third straight day, a split that matters more than the headline for concentrated portfolios.

The TSX Composite closed positive Monday even though decliners outnumbered advancers. Three gold miners masked the gap while Linamar, Magna and BRP absorbed the week's clearest trade war losses.

Friday's TSX gain was narrower than the headline number suggested. This morning's currency move is the cleaner signal for how seriously markets are taking the trade dispute.

The TSX Composite closed nearly unchanged Thursday even as banks fell and gold miners rallied sharply, with today's session set to turn on whether the US and Canada finalize a trade deal before tonight's tariff deadline.

The TSX Composite closed nearly flat after gold miners and Canadian banks moved double digits in opposite directions, while US indices fell broadly on a semiconductor selloff ahead of the FOMC minutes.
