SPY 1-day forecast by DeepSeek

The model's reasoning

(1) What I found: SPY is trading at $764.95 as of 10:03 AM ET on September 29, 2026, down 0.09% from the prior close of $765.61 (Futunn). The ETF opened at $766.70 and has traded in a $764.60-$766.95 range. Premarket action was choppy, with SPY quoted at $765.32, down 0.038%, as investors weighed a tech rebound against geopolitical tensions (Benzinga). The 10-year Treasury yield stands at 5.24%, and the 2-year at 4.94% (Benzinga). Markets are pricing a 72.5% probability of a Fed rate hike in October (CME FedWatch via Benzinga). The S&P 500 closed Monday at 7,683.69, down 0.77%, with the Dow falling 0.67% and the Nasdaq dropping 0.92% (Benzinga).

(2) Market regime: SPY is in a negative-gamma regime, trading below the $767 gamma flip point (KuCoin). Dealers are short gamma in this zone, which amplifies moves in both directions. The ETF is hovering just above the critical $764.76 support level that has held for five consecutive sessions (TradingView). Retail sentiment remains "extremely bullish" (Stocktwits), creating contrarian risk. The VIX rose 8.07% to 16.07 on Monday, signaling elevated uncertainty.

(3) Price range justification: I am using a $758-$772 range. The lower bound reflects the major weekly support at $750-$754, with the first support at $761 (TheoTrade). A break below $764.76 would likely accelerate toward $758. The upper bound is capped by the $770-$772 resistance zone, which includes the gamma flip point and the 770.09 shelf lost on Monday (TradingView). SPY's average daily range is roughly $8-$10, so a $14 range is consistent with current volatility. The range is skewed to the downside given the negative gamma positioning and macro headwinds.

(4) Catalysts: The primary catalyst is the JOLTS job openings and Consumer Confidence data at 10:00 AM ET, followed by Fed speakers Goolsbee (1:00 PM ET) and Williams (2:00 PM ET). Geopolitical tensions between the US and Iran remain elevated, with Trump dismissing sanctions relief as a "HOAX" (Benzinga). No SPY-specific events are scheduled, but the macro data and Fed commentary could trigger sharp intraday moves.

(5) Counter-argument: The strongest bull case is that the $764.76 support has held repeatedly, and the premarket tech rebound (QQQ up 0.4%) could spill over into the broader market. If SPY reclaims $767 and closes above it, the negative gamma pressure would ease, opening the path to $770-$772. A close above $772 would invalidate the bearish thesis. Conversely, a breakdown below $761 would confirm the bearish continuation and open the door to $750-$754.

(6) Confidence: I set confidence at 60% because the technical setup is clear - SPY is pinned below the gamma flip with negative dealer positioning - but the 1-day horizon is noisy and the support level has proven resilient. The macro data and Fed speakers introduce event risk that could trigger a breakout in either direction. The confidence reflects a modest bearish tilt rather than strong conviction.

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.
