Records at $100 Oil: What the S&P 500’s New High Actually Tells Canadian Investors

U.S. equity markets did something Wednesday that has happened only a handful of times in modern market history: they closed at all-time records with Brent crude simultaneously above $100 per barrel. The S&P 500 has now fully erased all of its Iran war losses. The Nasdaq set an intraday all-time high. The Dow closed within striking distance of 50,000. On the surface, this looks like a market that has decided the conflict does not matter. A closer reading suggests something more precise and more fragile.

What the Rally Is Actually Pricing

Two distinct forces drove Wednesday’s move, and conflating them produces the wrong analytical conclusion. The first was the ceasefire extension. Trump’s announcement Tuesday night removed, at least temporarily, the tail risk of a rapid escalation toward direct confrontation with Iranian military assets in a way that would have drawn in regional allies and potentially triggered a broader theatre of conflict. Markets priced that removal of acute escalation risk immediately and correctly. The S&P 500 had already recovered most of its war losses before Wednesday’s session; the ceasefire extension completed the move.

The second force is the earnings season, and it is doing more analytical work than the ceasefire narrative in explaining why the S&P 500 is at records rather than merely recovering toward them. More than 80% of S&P 500 companies that have reported so far have beaten either earnings or revenue expectations, according to FactSet data cited by CNBC. Boeing gained 5.5% after reporting a smaller-than-expected Q1 loss. GE Vernova jumped nearly 14% on revenue that topped expectations and raised guidance tied to datacenter power demand. Tesla beat adjusted EPS estimates of $0.35 by posting $0.41, with gross margin at 21.7% versus the 17.7% estimate. United Rentals surged after raising full-year guidance.

The earnings picture is telling a story about corporate resilience that the geopolitical headlines are obscuring: U.S. companies are, in aggregate, absorbing higher energy input costs and delivering results above expectations. That is not a trivial signal. It suggests the earnings channel through which $100 oil damages equity valuations is, at least for now, more muted than historical models would predict. The AI infrastructure buildout in particular is generating capital expenditure and revenue that appears largely insulated from commodity price inputs.

The Semiconductor Streak and What It Means

Chip producers have now risen for 16 consecutive sessions. Broadcom, AMD, and Micron each gained between 5% and 8% on Wednesday. GE Vernova’s guidance lift, tied explicitly to datacenter power demand, confirmed that the AI infrastructure cycle is translating into real revenue for the companies that build, power, and supply it. Texas Instruments posted strong quarterly earnings driven by industrial and automotive demand recovery.

Sixteen consecutive up sessions in any sector warrants scrutiny about whether the move reflects fundamentals or momentum. In this case, the evidence leans toward fundamentals. The datacenter buildout is a multi-year capital cycle with committed spending from hyperscalers that does not reverse quickly because of a geopolitical event in a different part of the global economy. The semiconductor cohort is benefiting from a structural demand driver that is largely orthogonal to the Hormuz disruption. That orthogonality is precisely why the Nasdaq outperformed the Dow and S&P 500 on Wednesday: the technology complex is priced on a different set of inputs than the energy-sensitive industrial economy.

The TSX Divergence and Canadian Implications

The TSX closed up only 0.43% Wednesday, a muted response relative to the S&P 500’s 1.05% gain and the Nasdaq’s 1.64% move. The divergence reflects the TSX’s composition. Canadian energy holdings, which constitute roughly 16% of the index, benefit from $100 Brent and provided support. But the TSX’s largest sector weighting, financials at 32%, faces a more complicated environment: the BoC holding rates at 2.25% while inflation rises and growth softens is not the backdrop that drives Canadian bank earnings higher. Materials, at nearly 20% of the index, are subject to their own commodity dynamics that do not move in lockstep with energy.

For Canadian investors watching U.S. indices hit records, the question is not whether to shift allocation toward U.S. equities in pursuit of the semiconductor-led momentum. That trade has already run significantly. The more useful analytical frame is to recognize that the TSX’s relative underperformance this week reflects sector composition differences, not a fundamental deterioration in Canadian corporate earnings quality. Canadian energy is outperforming. Canadian financials are facing a genuinely complex macro backdrop. The blended result is an index that lags U.S. tech momentum but is not signalling systemic weakness.

The variable to watch Thursday afternoon and into Friday is whether U.S. futures stabilize after the morning’s Iran-related pullback. The S&P 500 opened softer Thursday as the Navy tanker seizure and Trump’s mine-boat order reminded markets that the ceasefire extension did not resolve the strait. If the index holds near Wednesday’s close, the earnings season thesis retains control of the narrative. If it gives back more than 1% from the record, the geopolitical risk premium that equity markets have been discounting may be due for a reassessment.
