Insights from last week's changes in investor sentiment:

Investor sentiment remained range-bound last week, fluctuating between mildly positive and mildly negative as investors struggled to make sense of conflicting economic signals. The ongoing gap between market performance and sentiment persisted in most regions, narrowing only in the US, UK, and other developed markets. A lack of transparency, consistency, and clarity about the fundamental economic outlook is translating into a lack of confidence, direction, and consensus among global investors. This uncertainty is likely to persist in the near term, especially as the leading effects of tariffs begin to show up in lagging economic data in Q4.

Markets and sentiment have been locked in a cat-and-mouse game for weeks, with no clear end in sight. As of last Friday, the cats appear to be regaining the upper hand in the US, UK, and Global Developed markets. Elsewhere, the game remains too close to call. This market dynamic mirrors similar games unfolding in the macroeconomic arena—between inflation and employment—as well as in geopolitics, where war and peace are in constant tension, and in global trade, where protectionism and free trade continue to spar. Just like in these broader battles, there’s no definitive winner yet. Investor sentiment seems to mirror this uncertainty, even as markets persist in assuming that, eventually, the cats will always win, appearances be damned.

Believing something intensely does not make it true. It makes it comfortable. That's not the same thing. A strong conviction, either bullish or bearish, makes believing news that confirms this belief that much more 'comfortable' and gives investors the confidence to act on it (buy or sell). A disconfirming news feels ‘uncomfortable’ - if we didn't see this coming, what else are we missing? This discomfort often leads to underreaction, as self-doubt creeps in, thereby avoiding the kinds of investment decisions that might spawn consequences.

Risk-tolerant investors are dreamers in a hurry, who want to turn a little money into a lot as fast as possible. Risk-averse investors are dreamers too - otherwise, they wouldn’t be in the market - but they feel no urgency about bringing their dreams to fruition. Time is the great divider here. Given the uncertainty created by conflicting signals from the economy, politics, and geopolitics, investors have adopted a two-pronged approach: short-term bets that don’t require news confirmation, and longer-term positions that do. The former tends to cluster around the AI theme, while the latter focuses on the direction of interest rates - the only two ‘known unknowns’ investors feel they can rely on. Betting on anything else, given all this uncertainty, only leads to regrets. Regrets lead to turnover, turnover to expenses, expenses to underperformance, underperformance to bad publicity, bad publicity to redemptions, and redemptions to the poorhouse.

Last week’s FOMC meeting delivered the expected 25bps rate cut, but the dysfunction evident in the dot plot did little to ease investors’ concerns about the Fed’s independence next year. For many, the Fed’s very nature is to be independent from politics. But they aren't so sure that Trump, a practical man, would concede that this was the Fed's intended nature to begin with; and if it was, it is probably the executive branch’s duty either to deny it or to whip it into shape, show it who’s boss.

Given how important the Fed’s independence is to both domestic and foreign investors, now is the time for the administration to clarify its stance. For some, last week’s FOMC meeting may have marked the moment when “now” quietly slipped into “then”.

Note: green background = bullish, red background = bearish

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.
