SPY 1-day forecast by DeepSeek V3

The model's reasoning

(1) What I found and where: SPY closed Wednesday at $767.81, down 0.72%, per TheStreet Pro's most-active ETF table and futunn's session data. The futunn quote page shows SPY at $765.30 as of Sep 24 10:51 ET (14:51 UTC), down 0.33% intraday, with an open of $763.96 against a prior close of $767.81. The S&P 500 cash index was at 7,687.70 by 10:34 ET, down 0.24% on the day, per CNN's live markets feed. These are the freshest prints I could retrieve inside the window; the price I report is the futunn intraday quote, the closest available to the 15:07 UTC baseline.

(2) Market regime: The dominant driver is a global bond sell-off. The 10-year Treasury yield pushed to 5.15% Thursday morning, its highest since 2007, while the 30-year hit 5.45%, a level last seen in 2004. September flash PMIs came in at a five-year high of 58.4 for the composite, which traders read as fuelling further Fed tightening: CME FedWatch via CNN showed the odds of an October hike at 64%, up from 11% a month ago. Brent crude traded near $105 on Middle East supply risk, compounding inflation fears. The dollar index held near a two-month high above 101. SPY saw $22.64 billion of outflows in the week to Sep 18, per GuruFocus. VIX was around 16.4, its highest of the week but still low by 2026 standards. The regime is a yield-driven de-rating of equities, not a growth scare.

(3) Price range justification: I am using the futunn intraday print of $765.30 as the anchor. The day's range so far spans $763.62 to $766.43 per futunn, and the prior session printed a $766.50 low against a $773 high. The nearest support shelf sits at $761.76, the original breakout floor cited by TradingView's virDeStatera, with a deeper gap zone at $757.45 and the September 16 low at $749.60. Overhead resistance is at $770.09, the shelf lost Wednesday, then $773-$775, the recent high zone, and the 52-week high of $777.44. Daily implied volatility from SPXW options pricing was about 0.48% per Saxo, roughly 3.7 SPY points, but with the Trump-Xi summit running through the session I have widened the band to about 8 points below and 6 points above. The asymmetry reflects the yield and rate-hike overhang.

(4) Catalysts inside the window: The Trump-Xi summit is the single largest event. Closed-door meetings were expected to begin around 11:30 ET (15:30 UTC), with trade truce extension, AI cooperation, rare earths and Taiwan arms sales on the agenda. Treasury Secretary Scott Bessent announced a two-month extension of the Busan Agreement truce to January 10, a de-escalation signal but shorter than some had hoped, and Chinese markets sold off on summit scepticism. Fed speakers Barkin, Hammack and Paulson were scheduled through the afternoon, and US August new home sales were due at 14:00 GMT. Any headline from the summit or a hawkish Fed comment can move the tape sharply.

(5) Strongest counter-argument and invalidation: The bull case rests on the summit producing a concrete trade breakthrough that forces a short-covering rally, plus the fact that VIX remains in the low end of 2026's range and the S&P 500 is still within 2.5% of its 52-week high. Energy is the only sector holding gains, and a fading oil spike would relieve yield pressure. My call would be invalidated by a sustained move above $773 on heavy volume, which would signal buyers are looking through the rate story, or by a sharp pullback in the 10-year yield below 5% that removes the primary source of equity pressure.

(6) Why confidence is 62%: The macro backdrop is unusually one-directional, with yields, oil, the dollar and rate-hike odds all moving against equities simultaneously, and SPY-specific outflows confirm distribution. That argues for a stronger bearish conviction. However, a live superpower summit inside the window is a genuine two-sided event risk that can override the macro tape in either direction on a single headline, and the VIX at 16 is not pricing panic. A 62% confidence reflects a clear directional lean with meaningful event-driven uncertainty, not a high-conviction call.

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.
