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 AI rally meets yen intervention fears. & Analysis underpinning the 10-Year HMX 1.75 Probabilistic Forecast
The Nikkei 225's medium-term path is caught between structural tailwinds and acute macro risks. AI and semiconductor stocks keep drawing capital, buoyed by record foreign inflows and a surge in domestic retail shareholders. But the yen's plunge to multi-decade lows near 162 per dollar threatens to unwind the carry trade that's supported equities, and the Bank of Japan's gradual tightening could pressure valuations. Geopolitical flare-ups have shown how quickly oil price spikes revive inflation jitters, lifting JGB yields to 30-year highs. Over the next two months, the dominant story won't be earnings—it'll be whether the Finance Ministry's currency intervention threats materialize, and what that sudden yen strength would do to the export-heavy index's momentum.
The yen's 162 problem
Japan's currency is trading near 161-162 per dollar, a level that has officials openly talking about intervention. A weak yen has been a tailwind for Nikkei multinationals, but it's also driving import costs and complicating the BOJ's inflation fight. If authorities step in, the historical pattern is a volatile, sharp yen rally that often pulls the equity index down with it. For the next two months, that intervention risk is a live wire.
AI stocks aren't the whole index
Kioxia now tops Toyota in market value, and semiconductor gains have led the charge. But the Topix hitting record highs while the Nikkei flattens tells a different story—capital is rotating into banks, industrials, and consumer staples. This rotation suggests some investors are hedging tech exposure, worried that AI valuations have run ahead of near-term earnings. The medium-term question is whether that sector shift sustains the broader market if tech stumbles.
Bond yields at 30-year highs
Ten-year JGB yields have climbed to levels not seen in decades, partly on fears of political interference with BOJ independence. Higher yields traditionally pressure equity valuations, and they're already weighing on tech stocks sensitive to discount rates. With another BOJ hike expected in October, the bond sell-off could continue, acting as a steady drag.
HMX 1.75 Probabilistic forecast chart for Nikkei 225, plotting roughly 4 years of price history against a 2 years forward projection. History across the 4 years window has been relatively steady: price gained 156% off a start around 26800 JPY, peaking near 71300 and at one point pulling back about 18% from its running high. Today the price is approximately 68600 JPY (about 4% under the window high); on the forecast it sits inside the 1 year interquartile range, i.e. broadly fairly valued. Over the coming 2 years the central (median) estimate points to a gain of ~0%, landing near 68700 JPY. The P5 to P95 range is roughly 47% of the median and the band widens sharply with horizon. At the horizon the downside (P5) sits near 50900 JPY, about 26% below the current price, and the upside (P95) near 82900 JPY, about 21% above it. Overall the spread is downside-skewed (a fatter tail toward lower prices). 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. Operated by Heatmup Oy.
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.

('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. Full definitions, interpretation ranges, and validation status are set out in the Accuracy and Calibration Methodology at heatmup.com/accuracy, heatmup.com/accuracy-methodology.',)
