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.

S&P500 Tests Record Highs Amid AI Earnings and Rotation & Analysis underpinning the 10-Year HMX 1.75 Probabilistic Forecast
The S&P500 is brushing against its June peak, buoyed by expectations for around 23% earnings growth this quarter. That optimism is rooted in AI capital spending, but it's set a high bar that could spark volatility when reports start. Under the surface, money is moving out of tech giants and into cyclicals, improving market breadth even as the cap-weighted index stalls. Geopolitical risks haven't disappeared—oil price shocks from Middle East tensions are a live wire—but a soft jobs report has temporarily eased fears of Fed rate hikes. Over the next two months, the index's path likely hinges on whether corporate profits can justify current valuations, and if the rotation sustains or reverses.
The Earnings Bar is Set High
Analysts expect S&P500 earnings to grow around 23% year-over-year for Q2, with tech and energy leading. That's a steep climb, reflecting the AI investment boom, but it also raises the risk of disappointment. The upcoming earnings season, starting in mid-July, could be a volatility catalyst if companies miss these elevated estimates. It's not just about growth; it's about whether the numbers support the narrative that's pushed the index so close to records.
Rotation Without the Rally
For weeks, the equal-weighted S&P500 has lagged the cap-weighted version, but now small caps are outperforming large ones. Money is flowing from the Magnificent Seven into sectors like industrials and financials. This shift signals that investors are hunting for value beyond overstretched tech names. It doesn't guarantee a broader rally, but it could provide a steadier foundation if tech wobbles.
Oil Prices and the Fed's Calculus
Geopolitical flare-ups in the Middle East have pushed oil prices higher, reigniting inflation concerns. Yet, a weak June jobs report—just 57,000 payrolls—has cooled expectations for Fed rate hikes. The tension between these forces keeps the market in check, with bond yields rangebound around 4.55%. Over the medium term, the Fed's reaction to data will matter more than any single headline.
Insiders Keep Buying Tech
Despite investor anxiety over massive AI capital expenditures, insider buying in tech companies has been aggressive over the past six months. That's a contrarian signal, suggesting that those closest to the business see more value than the market does. It doesn't guarantee a rally, but it adds a layer of support that's often missed in broader sentiment readings.
HMX 1.75 Forecast chart for S&P500: about 4 years of recorded history on the left, a 2 years probability fan on the right. History across the 4 years window has been relatively steady: price advanced 96% off a start around $3860, peaking near $7580 and at one point pulling back about 17% from its running high. Price now stands near $7580, around 0% at the window peak, and relative to the projection it lies inside the 1 year interquartile range, i.e. broadly fairly valued. For the next 2 years, the median trends upward of roughly 1%, finishing around $7650. The P5 to P95 range is roughly 59% of the median with the band widening over the horizon. At the horizon the downside (P5) sits near $5430, about 28% below the current price, and the upside (P95) near $9940, about 31% above it. Overall the spread is roughly symmetric.

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.

For the next 6 months, the median projects a decline of roughly 1%, finishing around $7520. The P5 to P95 range is roughly 18% of the median with the band widening over the horizon. At the horizon the downside (P5) sits near $6710, about 11% below the current price, and the upside (P95) near $8070, about 7% above it. Overall the spread is downside-skewed (a fatter tail toward lower prices).

What is the 1-year HMX 1.75 probabilistic forecast for S&P 500 July 2026?
S&P500 1-year-forecast median is $7670 ($6110 to $8920), wide. HMX 1.75 Forecast chart for S&P500: about 4 years of recorded history on the left, a 1 year probability fan on the right. Over that 4 years window the price was relatively steady, climbed 96% from about $3860 to a window high near $7580, with a deepest peak-to-trough drawdown of roughly 17%. The current price is about $7580, sitting roughly 0% at the window high. Against the forecast it falls inside the 1 year interquartile range, i.e. broadly fairly valued. For the next 1 year, the median points to a gain of roughly 1%, finishing around $7670. The P5 to P95 range is roughly 37% of the median with the band widening over the horizon. At the horizon the downside (P5) sits near $6110, about 19% below the current price, and the upside (P95) near $8920, about 18% above it. Overall the spread is roughly symmetric. One caveat: the median rises to about 7770 before easing roughly 9%, 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. Full definitions, interpretation ranges, and validation status are set out in the Accuracy and Calibration Methodology at heatmup.com/accuracy, heatmup.com/accuracy-methodology.',)
