SPY 1-day forecast by Perplexity

The model's reasoning

(1) Market regime: SPY is trading near $767.77 around the requested 15:22 UTC window. Available September 25 intraday data places the ETF near $767-$768, while the prior regular-session close was reported at $767.18 after a September 24 range of $763.25-$768.95.

(2) Technical synthesis: The broader index backdrop is constructive over longer horizons, with SPY reported up approximately 12.5% since the beginning of 2026 and the S&P 500 near record territory. The immediate tape is much less directional: price is near the prior close, and current reporting describes stocks as steady or only modestly higher as AI optimism offsets elevated oil prices and Treasury-yield concerns.

(3) Price range: I estimate a one-day range of $763-$772. The lower bound aligns with the prior session's low and sits near the lower edge of the options-implied expected move; the upper bound is below the reported expected-move ceiling of $774.21 but allows for a retest of the current session's high area. Options pricing for September 25 implied an expected move of approximately plus or minus $4.43 from the prior close, supporting a moderately wide but not extreme range.

(4) Catalysts: No SPY-specific scheduled corporate event applies because the ETF tracks the S&P 500. The key one-day drivers are macro and index-level: oil prices, Treasury yields, inflation expectations, Middle East developments, and continued concentration of performance in large technology and AI stocks. Reuters reported that AI optimism was offsetting concerns about high oil prices and rising yields, while later market coverage described the S&P 500 as little changed.

(5) Counter-argument: A renewed bond selloff or oil-price spike could push SPY through the recent $763 area and produce a downside extension below the forecast range. Conversely, a sustained move above the current-session area near $768-$769, supported by easing yields and continued technology strength, would invalidate the neutral near-term view and make a test of $772 or higher more plausible.

(6) Confidence: Confidence is 51% because the price is current and options-implied volatility provides a useful one-day framework, but the index is being pulled in opposite directions by strong technology leadership and macroeconomic risk. The neutral 1h and 1d signals reflect the narrow current-session movement; mildly bullish longer signals reflect the strong year-to-date trend rather than a firm prediction for the next trading day.

How this forecast is measured

Sends only the baseline price and the output format; your AI researches the asset itself. Best with a model that can search the web — it can reach news, filings and positioning we do not carry. Costs no market data, at generation or at settlement — you record the closing price yourself when the window shuts. The monthly allowance is what a membership buys, not a data bill.

Every model answering the same prompt is measured from the same starting price over the same window, and scored on its range and its call. How scoring works · All shared research.
