Fiera Capital Global Asset Allocation

Global equity markets rose 5.0% in May to fresh highs as enthusiasm around the AI boom and optimism for a US-Iran truce boosted risk appetite. The article highlights broad risk-on sentiment, with AI stocks driving the move and easing Middle East conflict fears supporting equities. The message is constructive for market sentiment, though it reflects macro mood rather than company-specific developments.

Analysis

The cleanest read is that this is less about fundamental earnings revision and more about a positioning/flow regime where crowded winners are being rewarded for being crowded. That matters because AI leadership can keep indexing higher for longer than fundamentals justify, but it also makes the tape fragile: when breadth narrows this much, marginal buyers become price-insensitive until they suddenly are not. In practical terms, the market has likely moved into a “good news is not enough” phase for the rest of cyclical equities, while capex beneficiaries of AI remain the primary sink for new risk capital.

The second-order effect is that the AI complex is now pulling multiple adjacent industries into the same trade: semis, advanced packaging, power infrastructure, data-center cooling, and high-quality industrial automation. That creates a relative-value opportunity versus broad market beta, because the winners are increasingly the picks-and-shovels rather than the headline AI platforms. If sentiment cools, those supply-chain beneficiaries should de-rate faster than the megacap software names because they have less pricing power and more earnings sensitivity to capex cadence.

Geopolitically, any easing in Middle East risk tends to compress the volatility term structure, which supports equities through lower tail-hedging demand and less energy shock premium. But this is a tactical tailwind, not a durable regime shift: the market is pricing an orderly de-escalation that can be reversed quickly by a single incident. The main contrarian point is that the rally may be masking deterioration in breadth and making investors underappreciate how much of the advance is financed by short-vol and underweight re-risking rather than true macro improvement.

Key Decisions for Investors

• Stay long the AI supply chain, but express it via quality relative value: long SMH / short equal-weighted cyclical industrials for 1-3 months. Risk/reward favors continued capex spillover; stop if semis underperform the market by 5% over 2 weeks on weakening data-center order commentary.
• Sell upside volatility in the broad market via short-dated SPX call spreads if breadth remains narrow for another 1-2 weeks. The tape is strong, but realized vol should stay suppressed unless geopolitics re-accelerate; keep hedged with a small long VIX tail.
• Pair trade: long NVDA/AVGO vs short lower-quality semiconductor equipment names on any strength over the next 2-4 weeks. The thesis is that platform leaders can sustain multiple premium, while capex-adjacent names are more exposed to any pause in AI spending.
• Buy one-to-two month downside protection on XLE or unhedged airline/consumer discretionary baskets. If geopolitical optimism fades, energy and risk-sensitive consumer names should react fastest; use ~10-15 delta puts to limit carry.
• Avoid chasing broad beta here; prefer adding on pullbacks of 3-5% in AI leaders rather than breakout levels. Momentum is intact, but upside from current sentiment is likely lower than the downside if breadth cracks.
