Insights from last week's changes in investor sentiment:
Investor sentiment was broadly unchanged last week, with the only notable move coming from Japan, where investors turned bearish. Ongoing concerns that new stimulus measures may eventually be offset by fiscal tightening and higher rates – evidenced by the bond market - pushed Japanese sentiment deeper into negative territory. Global Emerging Markets sentiment remained bullish, even as Chinese investor sentiment slipped from neutral into negative. The overall stability in sentiment reflects declining market risk, and should not be misinterpreted as a renewed willingness to take on more of it. The combination of lower volatility and lower trading volume suggests that investors are pausing rather than positioning - waiting for companies to “show me the earnings.”
Despite markets hitting fresh consecutive highs, investor sentiment across regions remains well below last summer’s peaks. This persistent divergence underscores the absence of strong conviction and a continued wait‑and‑see stance, with investors requiring more reassurance. In 2025, company CEOs were given the benefit of the doubt and market gains were driven largely by multiple expansion; in 2026, investors will need to see actual earnings growth to justify current valuations and ease lingering bubble concerns.
In the US, the 20‑day average USD trading volume has continued to decline since late November, and is now back to levels last seen in September. At the sector level, the standout exception remains, unsurprisingly, technology, and specifically AI‑related stocks. The AI theme appears uniquely exempt from the usual burden of earnings proof. Familiarity, it seems, trumps everything else. Why else would investors keep making the same mistakes over and over?
The Venezuela, Iran, and Greenland developments over the past few weeks have made it clear that the geopolitical noise of 2025 will only get louder in 2026, becoming deafening at times. Markets will become event-driven rather than assumption-driven (e.g. do not assume NATO will hold if the US takes Greenland by force). In the best‑case scenarios, this will simply translate into two‑way volatility spikes across markets, making any sudden investment decisions look, in hindsight, ill-bred.
The list of geopolitical events that could slip into worst‑case scenarios is already long - Venezuela, Iran, Greenland, Colombia, Mexico, Cuba - and could very well get longer. Add to that the growing roster of domestic political flashpoints - elections, protests, Supreme Court decisions, questions around Fed independence, and ongoing immigration operations - not to mention the unfinished hot wars in Ukraine and Gaza. In 2025, the AI theme was strong enough to absorb these risks; but as last November reminded investors, in 2026 it could just as easily transmit them across markets instead.
In short, the current lackluster, mostly neutral sentiment across markets reflects a shift in investors’ relationship with the AI theme: they still ‘love’ it, but are no longer ‘in love’ with it. Love is what’s left when the blindness, excitement, and passion of being ‘in love’ that fades with time has gone. Investors still care about the theme, still want it to succeed, but the illusions are gone - and the “blind eye” has quietly been turned back to its original ON position. That kind of love is more enduring, but also far more discriminatory about what behavior (read: “valuation”) it is willing to put up with, and it reflects a clear shift in investors’ risk‑reward calculus in 2026.

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.
