Market Context

Canadian growth and technology stocks are heading into a pivotal week following one of the roughest stretches for global semiconductor names in recent months. What began as sentiment-driven volatility tied to oil and geopolitics has increasingly become a story about AI valuations themselves, following a competitive announcement out of China that rattled chip stocks to close out last week.

What Happened

The VanEck Semiconductor ETF posted its third weekly decline in four weeks, dropping almost 9% over that period, with Friday’s session hit especially hard after Chinese AI startup Moonshot AI unveiled a new model it said narrows the gap with leading U.S. offerings. That news compounded a difficult week for U.S. technology stocks broadly, with the Nasdaq Composite falling 2.9% and the S&P 500 down 1.6%. On the TSX specifically, Celestica extended losses of more than 6% Friday following a 9.3% plunge in the prior session, while Shopify fell around 1.4% and Constellation Software declined 0.9%, both caught up in the broader technology selloff despite no company-specific news driving the moves. This week brings a critical test of whether the underlying AI infrastructure narrative can stabilize, with Tesla and Alphabet both scheduled to report earnings, and Alphabet in particular expected to address capital expenditure guidance that markets are watching closely for signs of continued AI investment commitment.

Why It Matters

Moonshot AI’s announcement represents a genuine shift in the competitive narrative around AI models, not just another sentiment-driven wobble. If Chinese AI labs are closing the technical gap with U.S. leaders more quickly than markets had assumed, that raises real questions about the pricing power and moat assumptions embedded in many AI infrastructure valuations, extending beyond just semiconductor names.

This week’s earnings from Alphabet carry outsized importance for the broader AI capital expenditure story. Analysts are watching closely for whether the company raises its capex guidance meaningfully, potentially into the $275 billion to $325 billion range for next year, as a signal of whether hyperscaler spending commitments remain intact despite last week’s valuation jitters.

Sector Breakdown

Within Canadian technology, Celestica’s sharp declines reflect its direct exposure to the semiconductor supply chain, making it particularly sensitive to shifts in AI infrastructure sentiment. Shopify and Constellation Software, while less directly tied to chip manufacturing, have continued to show sympathy moves with broader technology sentiment, illustrating how closely intertwined Canadian growth stocks have become with the global AI narrative. More speculative names, including Xanadu Quantum Technologies, tend to see amplified moves during periods like this, given their valuations rest more heavily on distant future outcomes that become harder to underwrite amid rising competitive uncertainty.

Risks to Watch

The most significant risk is that Moonshot AI’s announcement marks the start of a broader reassessment of AI infrastructure spending assumptions, rather than an isolated data point, which could pressure valuations across the sector well beyond this week. A disappointing capex signal from Alphabet’s earnings this week could compound that pressure significantly, given how closely markets are watching hyperscaler spending commitments. Continued volatility in oil prices and broader geopolitical developments could also add to risk-off sentiment that has already weighed on growth stock valuations over the past week.

What to Watch Next

Investors should watch this week’s earnings from Alphabet and Tesla closely, particularly any commentary on AI capital expenditure plans. Continued developments around Moonshot AI’s new model and its reception among enterprise customers will be an important gauge of whether the competitive threat is being taken seriously by the market. Broader semiconductor sector performance, following its third weekly decline in four weeks, will also be worth monitoring for signs of stabilization or further deterioration.

Final Outlook

Last week’s combination of a fresh Chinese AI competitor and broader risk-off sentiment has introduced a genuine new source of uncertainty into the AI infrastructure trade, beyond the geopolitical and rate-driven volatility that had dominated prior weeks. This week’s earnings from Alphabet and Tesla will be an important test of whether the underlying spending story remains intact.
