SPY 1-day forecast by DeepSeek

The model's reasoning

(1) What I found: SPY was trading at $767.65 as of 13:19 ET (17:19 UTC) per futunn.com, down 0.74% on the day, after opening at $772.79. The premarket quote was $774.02. The S&P 500 index was down 0.61% to 7,717.30 per Economic Times, while the Nasdaq fell 1.21%. The 10-year Treasury yield hit 5.04%, its highest since 2007, and the dollar index rose to 101.02, a near two-month high. Brent crude rose 2% to $101.92. The main macro release was the September Flash PMI at 9:45 AM ET, which came in hot at 58.4 composite, reinforcing rate-hike expectations after last week's 25bp hike.

(2) Market regime: Risk-off intraday. Rising yields, a stronger dollar, and higher oil prices are pressuring equities. Breadth is narrow and deteriorating: nine of eleven S&P sectors are in negative territory over the past month, and semiconductor stocks are leading losses (AMD, Nvidia, Intel all down, SOXX off 1.5%). SPY is testing the $766-767 support zone that has held for three sessions. The intraday trend is clearly lower, with SPY making lower highs and lower lows since the open.

(3) Price range: I am using $762-$775, with more room below than above the current quote. Support is clustered at $766.25 (eoption.com) and $765.52 (TradingView reclaim level). A decisive break below $765.52 opens the structural floor at $761.76. Resistance is at $773 (eoption.com) and $775.30 (TradingView session high). The average daily range for SPY over the past week has been roughly $6-8, so a $13 range over 24 hours is consistent with current volatility.

(4) Catalysts: The September Flash PMI (58.4) was the main catalyst and has already been digested, with the hot reading driving yields higher and pressuring equities. The 5-Year Note Auction at 1:00 PM ET is a secondary catalyst; weak demand could push yields higher and weigh further on SPY. Fed Governor Barr's fireside chat at 10:05 AM ET has passed. The US-China summit and Middle East talks are ongoing but no specific market-moving outcomes are expected within the 24-hour window.

(5) Counter-argument: The bullish case rests on Monday's powerful rally and the fact that SPY has held above the $765.52 reclaim level for three consecutive sessions. If buyers defend $766 and yields stabilize, SPY could bounce back toward $773-775. The strongest invalidation of my bearish lean would be a close back above $773 on strong volume, which would suggest the intraday selling was absorbed and the uptrend is resuming. The low aSOPR in equities and resilient ETF inflows also argue against a sustained breakdown.

(6) Confidence: 55%. The bearish case is supported by three concrete macro headwinds (yields at 2007 highs, dollar at a two-month high, oil up 2%) and weak market breadth. However, the market has shown resilience, and a 1-day horizon is inherently noisy. A confidence of 55% reflects a modest directional edge, not a high-conviction call. I would have more confidence in a 7-day bearish lean than a 1-day one.

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.
