The shaded band shows the range of outcomes the model calculates, not a single prediction. Each labeled
line is a percentile of that distribution.
The median (P50) is the calculated middle path: half of modeled outcomes fall above it, half below. The
inner band, between P25 and P75, holds half of all calculated outcomes. The outer limits, P5 and P95,
bound the 90% probability density layer, leaving 5% of modeled outcomes beyond each edge.
A wider band further out reflects greater uncertainty over longer horizons. These are modeled
probabilities, not guarantees. Past performance doesn't guarantee accuracy.

Nikkei's tech bet faces yen and oil shocks & Analysis underpinning the 10-Year HMX 1.75 Probabilistic Forecast
For the Nikkei 225, the next two months boil down to whether its tech-heavy composition can weather external storms. Semiconductor stocks like Advantest and SoftBank have driven 5% daily swings, tying the index tightly to global AI demand. But that reliance is a vulnerability when the yen hits 40-year lows, helping exporters but squeezing import costs for domestic firms. Geopolitical tension in the Strait of Hormuz has oil prices spiking, adding a direct hit to Japan's trade-dependent economy. The real story isn't just earnings; it's how currency moves and commodity shocks amplify every tech ripple, keeping volatility entrenched.
Semiconductor stocks don't just lead; they drag
When U.S. chip earnings surprise, the Nikkei moves. Friday's 5% surge saw Advantest up 16% and SoftBank limit up, but earlier in the week, a global selloff wiped 4% off the index. This concentration means a handful of names—often the same ones—swing thousands of points. Over the medium term, each major tech report will be a potential catalyst, and the index's path depends disproportionately on whether AI demand holds up against valuation concerns.
The yen at 162 isn't a tailwind for everyone
USD/JPY near 40-year lows creates a split market. Exporters like Fast Retailing and Toyota benefit from dollar revenue, but import costs for energy and materials are soaring. The Bank of Japan's rate hikes to 1.0% haven't stabilized the currency, and conflicting government messages add noise. For the next two months, this currency volatility isn't background; it's a direct earnings input that can override sector-specific news.
Oil prices from the Strait of Hormuz are now a daily input
Geopolitics has moved from risk to routine. Oil jumped 5% after U.S.-Iran clashes, and Japan's almost total reliance on imports means every spike hits corporate costs and sentiment. The market's reacting to tanker routes and insurance premiums, not just earnings. With tensions ongoing, this adds a layer of macro pressure that keeps volatility high and complicates any sustained rally.
HMX 1.75 Probabilistic forecast chart for Nikkei 225, plotting roughly 4 years of price history against a 2 years forward projection. Over that 4 years window the price was relatively steady, climbed 128% from about 28200 JPY to a window high near 71300 JPY, with a deepest peak-to-trough drawdown of roughly 18%. Today the price is approximately 64400 JPY (about 10% under the window high); on the forecast it sits inside the 1 year interquartile range, i.e. broadly fairly valued. For the next 2 years, the median points to a gain of roughly 1%, finishing around 65200 JPY. The P5 to P95 range is roughly 52% of the median and the band widens sharply with horizon. At the horizon the downside (P5) sits near 48800 JPY, about 24% below the current price, and the upside (P95) near 82600 JPY, about 28% above it. Overall the spread is roughly symmetric. Note the median is not monotonic: it peaks near 69100 then retraces about 10%, a spike-and-pullback shape that reflects disagreement among the aggregated inputs rather than a smooth trend. Produced by HMX 1.75, a raw aggregation model that combines independent predictions into a single probabilistic forecast; agreement among inputs is not consensus, and there is no guarantee of results.

Model Description
HMX 1.75 is the current production release of the Heatmup forecasting engine. It operates as an equally weighted baseline: every model in the ensemble pool contributes equally to the final distribution, regardless of individual track record. The output is a probability distribution over future price and time for each covered asset, rendered as a heatmap. Percentile bands (P5 to P95) capture 90% of modeled outcomes. Every generated distribution is archived with an immutable ID and public timestamp and resolved later against the realized market price. HMX 1.75 is not an AI system under the EU AI Act; it is a deterministic quantitative aggregation engine.

Methodology
HMX aggregates outputs from a proprietary pool of independent quantitative models operating in strict isolation. Each model produces discrete predictions (date, target price, probability) without visibility into the others. The HMX engine combines these inputs using time-decay weighting, which prioritizes recent data, into a single probability distribution per asset. The process is deterministic: identical inputs produce identical outputs. No machine learning is applied at inference. HMX 1.75 uses equal weighting, meaning every model in the pool contributes equally regardless of historical track record. Accuracy-weighted calibration, where model influence is proportional to resolved performance, is scheduled for HMX 2.0 in September 2026.

At the horizon the downside (P5) sits near 58500 JPY, about 9% below the current price, and the upside (P95) near 143000 JPY, about 122% above it. Overall the spread is upside-skewed (a fatter tail toward higher prices). One caveat: the median rises to about 148000 before easing roughly 43%, so the path is a spike-and-retrace rather than a clean trend, a sign of divergence between the underlying inputs.

('Calibration of HMX 1.75 is measured by assigning each resolved forecast to the percentile band containing its realized price, defined as the OHLC4 midpoint of the resolving bar, and aggregating these assignments across all covered assets and dates into a probability integral transform (PIT) histogram. All published metrics derive from this histogram and the computation is deterministic. Reported metrics are the calibration slope and intercept, Expected and Maximum Calibration Error (the latter equal to the Kolmogorov-Smirnov distance on the PIT under this binning), prediction interval coverage for the central fifty and ninety percent intervals, reduced chi-square PIT uniformity, and interval sharpness. These are summarized in the Market Intelligence Score, a proprietary Heatmup composite on a zero to one hundred scale that weights calibration error, tail behaviour, calibration slope, distributional uniformity, and sharpness; it is not an industry standard, and its normalization functions are published with the scoring code so the composite is auditable. The current figures describe the equally weighted baseline over the live resolved-forecast window to date and are computed by Heatmup Oy. The underlying resolved-forecast data and scoring code are published so the metrics can be independently reproduced and verified. Measurement of calibration is distinct from a representation that the output is calibrated or guaranteed; the score is a diagnostic.
