This week investors will focus on two stages sitting 2,000 miles apart. At Jackson Hole, central bankers will explain how firmly they intend to control events they are still trying to understand. In California, Nvidia will report how quickly it is building the infrastructure for a future everyone already claims to understand. Monetary policy and AI will compete for investors’ attention, with supporting roles for Hormuz and US-Canada trade negotiations. The common thread is anticipation. The ECB and BoJ are being priced for September rate increases, while US investors have reduced the odds of a Fed hike. Nvidia’s earnings, the US-Canada trade deal and Hormuz, meanwhile, show what happens when hope has gilded its own lily and become expectation.
The policy divergence matters because investors are no longer responding to a single global rate cycle. The ECB, BoJ and Fed are moving toward different decisions for different reasons, forcing investors to price currencies, discount rates and equity risk premia with less help from the comforting fiction of synchronization. Markets assign probabilities because decimals look disciplined, even when the speeches producing them retain the ambiguity of diplomatic communiqués. With investors giving roughly 90% odds to an ECB increase and 80% to a BoJ move, the burden at Jackson Hole falls less on signaling intent than on avoiding an accidental disappointment. That is a delicate balance when clarity is being rationed by the very institutions meant to deliver it.
ROOF Scores signal little aggregate reaction so far. The aggregate score is currently negative at -0.26, little changed from both last week and one month ago. The distribution is equally stable: two of the ten markets we track have positive sentiment, three are neutral, three negative and two bearish. The number of positive or bullish readings is unchanged over the month, as is the number of negative or bearish ones. In other words, the composition has shifted slightly, but the broad balance between risk-tolerant and risk-averse sentiment has not.
That stability conceals sharp national differences. Sentiment among Japanese investors is bearish at -0.95 after deteriorating materially over the past month and further over the past week. Their risk appetite is moving in the same direction across both horizons, confirming the downtrend as expectations of tighter BoJ policy harden. Chinese investors provide the mirror image: sentiment improved materially over the month and again last week on continued hopes for a stimulus package from the authorities, yet remains bearish at -0.98. A recovery from extreme pessimism is still pessimism, merely with better attendance. Investors in DM ex-US equities also improved their sentiment over both periods, but the current reading of +0.01 remains neutral. Across markets, dispersion is around the 61st percentile of its history, little changed from the 66th percentile a week ago, although well below the 88th percentile one month earlier. A common macro influence has reduced some of the earlier dispersion, but local conditions still have ample room to impact sentiment.
The US reading makes Nvidia’s earnings more consequential than the index-level anticipation suggests. Sentiment among US investors is currently negative at -0.41, little changed last week after deteriorating over the past month. In that emotional state, investors tend to under-react to reassuring news and overreact to disappointment. Jensen Huang will therefore need to pace the stage with more swagger than poise, and somehow occupy more space than physics allows, now that Nvidia has become both a supplier of computing equipment and a referendum on AI’s future. The results must validate demand, margins, capital spending and the growing conviction that every dollar allocated to AI infrastructure will eventually find a revenue stream willing to adopt it. The larger the promise, the smaller the margin for ordinary competence.
There is no confirmed early-turn configuration in any market. China, Japan and DM ex-US instead show weekly and monthly changes aligned in the same direction, while Australia offers a useful warning against reading a positive label too comfortably. Sentiment among Australian investors remains positive at +0.21, barely above the neutral boundary, after deteriorating materially over the month. Current classifications describe where risk appetite stands; the path explains how securely it stands there.
Jackson Hole and Nvidia will provide investors with plenty of material for funded conviction: rate probabilities, policy language, guidance, margins and whatever new unit of AI demand is chosen for ceremonial promotion. The useful question is whether that information changes the balance between risk tolerance and risk aversion, or merely gives existing positions a more presentable footnote. This week will supply the evidence. Conviction will decide which evidence is admitted.
The negative return on the Short side reminds investors that being a contrarian in a groupthink environment is like throwing an egg at an incoming bus. Most have decided it is safer to be on the bus than standing in front of it. Bubbles are the unbicycle of markets: investors never remember.
Aggregate ROOF Trend: The black line is the aggregate mean of ROOF scores across the ten markets; the shaded grey band shows the range from the most bearish to the most bullish market on each day, indicating the dispersion of sentiment across the universe. Reading it: a rising line indicates increasing risk tolerance; a declining line indicates increasing risk aversion. Bottom strip: cross-market dispersion percentile — the cross-sectional standard deviation of ROOF across the ten markets, percentile-ranked against its own full history. Shaded zones mark elevated (>80th percentile) and compressed (<20th) readings. Reading it: a spike into the top shaded zone is a material divergence episode (sentiment moving in different directions across markets), a slide into the bottom shaded zone is convergence on a common driver (sentiment moving in the same direction across markets).
Regime Distribution: Three horizontal stacked bars show how the ten markets are distributed across the five regimes — today, one week ago, and one month ago. Each bar is colored by regime: red (Bearish), yellow (Negative), grey (Neutral), blue (Positive), green (Bullish). The white vertical marker on each bar shows the aggregate ROOF score for that period. Tick marks below the bars align with the regime thresholds at ±0.20 and ±0.50. Reading it: a leftward shift over time indicates broadening deterioration; a rightward shift indicates broadening improvement. Widening tails signal rising dispersion.
Market Monitor
Market Monitor: A table showing, for each market: current ROOF score, current regime, weekly and monthly changes, regime one month ago, and distance to the nearest extreme threshold. Color cues highlight regime deteriorations (red) and improvements (green). Reading it: scan the "1M Ago Regime" column for markets that have crossed regime bands over the past month; check the "Distance" column to find markets close to the ±0.50 extreme thresholds.
Sentiment Correlation Matrix
Correlation Matrix (Δ1M): A heatmap of correlations between monthly sentiment changes across all market pairs, over a rolling 60-day window. Green cells indicate that investor sentiment in the two markets changed in the same direction; red cells indicate opposite directions. The rightmost column shows each market's average correlation with the rest of the universe. Important: these are correlations of sentiment changes, not market returns or ROOF levels. High correlation means investor mood in the two markets moved in sync over the past 60 days.
