AXIOMA ROOF™ SCORE HIGHLIGHTS

WEEK OF MAY 25, 2026

Potential triggers for sentiment-driven market moves this week

  • US: April’s personal income and outlays, the PCE price index. Q1 GDP revision.
  • Europe: Eurozone inflation, consumer and business confidence data.
  • APAC: China’s April industrial profit data. Japan’s unemployment, industrial production, retail sales, consumer confidence, and Tokyo inflation figures. Australia’s inflation data.
  • Global: Reopening Hormuz and restoring energy exports remains key for global markets.

Insights from last week's changes in investor sentiment:

We are ~12 weeks into the Hormuz closure and everyone is still talking about oil and how the energy shock is driving inflation. Two more supply shocks hide in the shadow of Hormuz: Urea, a key input into fertilizers, has already repriced sharply at $850/mt in April, up ~80% since February, and helium, a non‑substitutable process gas for semiconductors fabs - no high‑purity helium means yield loss or tool downtime. Fertilizer is the faster channel, already repricing and feeding into the next planting cycle, reinforcing second‑round inflation pressures. For helium, if disruption persists, even modest curtailments feed through with a lag given ~6‑month semiconductor lead times, pushing any chip supply shock into Q4. For inflation, energy was the first punch, fertilizer the second, helium is the late‑cycle uppercut.

That sequence is now starting to show up in both consumer confidence and market pricing. The US Consumer Sentiment Index plunged to a record low of 44.8 in May 2026 as consumers grew more worried that inflation would spread beyond fuel prices in the long term. Year-ahead inflation expectations edged up to 4.8% from 4.7%, while long-run expectations climbed to 3.9% from 3.5%. What worries investors isn’t just valuations (too high) or earnings growth (too concentrated), but inflation expectations and their impact on real yields which have already risen from 1.72% on February 27th to 2.18% last Friday. This rise in real yield might forces investors to reprice AI’s long-duration revenue promise by applying a higher discount rate on future revenues. For markets, this means that there is no longer a one-Fed-fits-all-investors: bond investors want a hawkish Fed that isn’t here yet, while equity investors want/need a dovish Fed that isn’t here anymore.

The Telecom Crash of 2001 showed what happens when capital races ahead of demand. In the late ’90s, operators didn’t just overbuild—they pre-sold decades of capacity via IRUs. When the cycle turned, as much as 80–95% of long‑haul capacity sat unused, not because demand was fake, but because capacity had arrived too early and been overestimated. Telecoms prepaid the future demand and waited a decade for it to show up. Abundant capital can build capacity, but only real workloads can fill it. Is the AI data center bubble a Telecom rerun?

The rise of AI stocks since the release of ChatGPT in 2023 has been phenomenal. Some worry that the sudden influx of new investors that accompanied this surge — none of them forged, as it were, in the fires of the Telecom Crash of 2001 — might have erased the memory of potential loss, and that investors might start taking ongoing record highs for granted. Like Adam watching Eve arrive in paradise and immediately ‘reach’ for something better…

Hormuz remains the biggest known unknown for markets. Once again, good intentions have collided with geopolitical reality: the war has dented US leadership credibility and, for now, lifted China. In May, Beijing appeared to replace Washington at the center of geopolitical gravity. China’s role, however, still leans more toward protecting allies than shaping outcomes. Markets reward outcomes, not unused influence. If others make the peace, Xi may find that what looked like leverage was only optionality—and that by not exercising it, he weakened his own hand.

As of Monday morning, talks of peace, in lieu of actual peace talks, are once again giving investors hope that Hormuz will be returned to its factory setting. Oil futures fell 5% last week on the ceasefire extension and another 5% this morning as both sides outlined their version of a longer truce—still limited to a partial reopening of Hormuz, with no clarity on whether transit will be free or pay‑to‑pass. For now, that addresses only a fraction of what a durable agreement would require: no progress on sanctions relief, blocked Iranian funds, the US blockade, or a comprehensive nuclear framework. Sentiment had already begun to recover across all markets and should continue to do so as investors focus on future oil prices instead of lagging inflation data due out this week. Pain forgets within the hour what it learns in an instant.

Note: green background = bullish, red background = bearish

Changes to investor sentiment over the past 180 days for the ten markets we follow: 

How to Interpret These Charts:

Top Charts:

The top charts illustrate the ROOF ratio, which represents investor sentiment. This ratio is depicted in green on the left axis, while the cumulative returns of the underlying market are shown in black on the right axis. Key reference lines include:

  • A horizontal red line at -0.5 (left axis), marking the threshold between negative sentiment (-0.2 to -0.5) and bearish sentiment (< -0.5).
  • A horizontal blue line at +0.5 (left axis), indicating the boundary between positive sentiment (+0.2 to +0.5) and bullish sentiment (> +0.5).
  • A horizontal grey line at 0.0 (left axis), around which sentiment is considered neutral (-0.2 to +0.2).

Bottom Charts:

The bottom charts display the levels of risk tolerance (green line) and risk aversion (red line) within the market, representing investors' demand and supply for risk, respectively. Key insights include:

  • When risk tolerance (green line) exceeds risk aversion (red line), more investors are willing to buy risk assets than there are investors willing to sell them at the current price. This scenario forces risk-tolerant investors to offer a premium to entice more risk-averse investors to trade, thereby driving markets upward.
  • Conversely, when risk aversion (red line) surpasses risk tolerance (green line), the market dynamics reverse.

The net balance between risk tolerance and risk aversion levels is used to compute the ROOF ratio shown in the top charts, reflecting the sentiment of the average investor in the market.

Blue Shaded Zone:

The blue shaded zone between levels 3 and 4 for both indicators signifies a reasonable balance between the supply and demand for risk in the market. When both lines remain within this blue zone, the market is considered ‘emotionally’ stable. However, when both lines move outside this zone, the significant imbalance in demand and supply for risk can lead to overreactions to unexpected news or risk events.
