SPY Stock Premarket Preview for December 1, 2025: S&P 500 ETF Eyes Santa Rally After Volatile November

The SPDR S&P 500 ETF Trust (ticker: SPY) heads into the first trading day of December trading near record highs, backed by a powerful holiday-week rebound but shadowed by heavy fund outflows, stretched valuations and growing worries about 2026.

As of Friday’s close, SPY finished at $683.39, up 0.55% in the shortened Black Friday session and capping a strong four-day run into month‑end. ^[1] Over the past week, the ETF is up about 1.6%, even as investors have pulled more than $6 billion from the fund over the last five trading days. ^[2]

S&P 500 futures trading on Sunday point modestly higher into Monday’s open, with contracts up roughly 0.4%–0.5% around 6,840–6,846, suggesting SPY could start December with a small gap higher if the tone holds. ^[3]

Below is what traders need to know about SPY before the market opens on Monday, December 1, 2025.

1. How SPY Finished November: From “Worst in Years” Fears to a Late Surge

A strong holiday week for the S&P 500 ETF

SPY’s late‑month rally mirrored a broader rebound in U.S. equities:

From Monday to Friday of Thanksgiving week, SPY climbed from about $668.73 to $683.39, a gain of roughly 2.2%, with four straight up sessions. ^[4]
The S&P 500 itself ended Friday at 6,849.09, up 0.54% on the day. ^[5]
Major U.S. indexes logged their best week since June, even as the tech‑heavy Nasdaq saw its seven‑month winning streak snapped for November. ^[6]

A TipRanks daily update attributes Friday’s SPY gain largely to a rally in semiconductor stocks, renewed optimism over potential Federal Reserve rate cuts, and firmer energy prices. ^[7]

A chaotic Black Friday, but a positive finish

Black Friday itself wasn’t drama‑free. A cooling problem at a CyrusOne data center triggered a CME Group outage that temporarily froze trading across key futures markets, including S&P 500 contracts. ^[8] The glitch was resolved before the U.S. cash session opened, allowing Wall Street to grind higher into the early 1 p.m. ET close. ^[9]

Despite the scare, the S&P 500 and Dow eked out small gains for November, while the Nasdaq dropped about 1.5%, as investors rotated away from richly priced tech names. ^[10] SPY, which tracks the S&P 500, ended the month near its highs.

2. Futures and Premarket Signals Heading Into December 1

Index futures point to a mildly higher open

Heading into Monday’s U.S. session:

S&P 500 futures recently traded around 6,845.8, up 0.48%, according to live futures dashboards. ^[11]
A separate snapshot shows S&P futures near 6,840.9, up about 0.42%. ^[12]

If those gains hold through the overnight session, they would imply a modestly positive open for SPY, potentially nudging the ETF toward the $686–$687 area. (Futures and fair‑value models, such as one that pegs a “predicted” S&P 500 open around 6,839.7 on December 1, are only rough guides and can shift quickly as liquidity builds in the morning. ^[13])

Volatility and “Santa rally” expectations

Market technicians are increasingly focused on seasonality. Research from EquityClock notes that over the past five decades, December has delivered an average S&P 500 gain of about 1.2%, with positive returns roughly 72% of the time, cementing its reputation as one of the market’s strongest months. ^[14]

A MarketWatch options column highlights that the two weeks after Thanksgiving are historically favorable and that a recent volatility “spike peak” in the VIX has generated a tactical buy signal that can last into Christmas, with some traders expressing that view using SPY call spreads. ^[15]

Taken together, the futures tone and seasonal backdrop suggest constructive but cautious sentiment for Monday’s open.

3. Flows vs. Price: SPY’s Quiet Tug‑of‑War

One of the more striking data points heading into December is the divergence between SPY’s price and its fund flows.

TipRanks’ weekend update reports that SPY is up 1.64% over the past week yet has seen a five‑day net outflow of about $6.33 billion. ^[16]

That kind of pattern—prices rising while investors pull money—often signals:

Profit‑taking: Longer‑term holders use strength to trim exposure after a volatile month.
Rotation within equities: Investors shift from mega‑cap‑heavy S&P 500 exposure toward other factor, sector, or equal‑weight strategies.
Skepticism about sustainability: Some participants are unconvinced that the rebound will persist into 2026.

This fits with a series of recent columns questioning whether investors have become over‑concentrated in traditional S&P 500 index funds, with one MarketWatch/Morningstar piece noting that about 40.6% of the index’s weight is now in just 10 companies, many of them AI‑linked tech giants. ^[17]

4. What SPY’s Factor Profile Says About Risk Right Now

A fresh SPY ETF Factor Report from Nasdaq and Validea, published November 29, offers a snapshot of how the S&P 500 ETF looks under the hood. ^[18]

Key takeaways:

Sector tilt: Technology is SPY’s largest sector, with software & programming the biggest industry group.
Factor scores (1–99 scale):
- Value: 30
- Momentum: 76
- Quality: 82
- Low Volatility: 60

In simple terms, SPY currently behaves like a high‑quality, momentum‑driven growth portfolio that is not especially cheap.

Combined with the concentration data from MarketWatch—top holdings like Alphabet, Nvidia, Apple and Microsoft collectively making up over 40% of the ETF—this profile underscores two important points for Monday’s open: ^[19]

Mega‑cap tech still sets the tone. Any sharp move in a handful of AI‑exposed leaders can swing SPY disproportionately.
Upside may come with air pockets. Strong momentum and quality scores are positives, but relatively low value exposure means pullbacks can be abrupt if sentiment turns.

5. Macro Backdrop: Fed Pivot, QT Ending and 2026 Warning Flags

Fed policy: QT ends December 1

On the policy front, the most immediate milestone is the Federal Reserve’s decision to end Quantitative Tightening (QT) on December 1, 2025, shifting back to reinvesting maturing securities instead of shrinking its balance sheet. ^[20]

Weighing on SPY for much of the year, QT has effectively withdrawn liquidity from the system. Its end is widely seen as:

Supportive for risk assets and Treasuries, potentially easing financial conditions.
A signal that the Fed is inching closer to a full pivot from tightening toward easing.

In Friday’s Reuters wrap‑up, futures markets were pricing in a 25‑basis‑point rate cut at the December Fed meeting, though officials have stressed that the odds remain data‑dependent. ^[21]

“Santa rally” vs. crash talk

Bullish seasonality is colliding with more cautious long‑term analyses. A recent Finbold piece flags a valuation‑based indicator that has historically preceded major S&P 500 drawdowns, warning of a potential “crash in 2026” even as the index closed Friday near 6,849, up roughly 0.5% on the session. ^[22]

Meanwhile, a Seeking Alpha note titled “After the S&P 500’s big Nov reversal, history suggests Dec will likely be green too” argues that when the index flips from deep early‑month losses to a positive finish—as it has just done—the probability of a positive December rises meaningfully, a constructive signal for SPY. ^[23]

The result is a tug‑of‑war narrative heading into Monday: short‑term seasonal and liquidity tailwinds versus medium‑term valuation and macro concerns.

6. Earnings, Data and Themes SPY Traders Will Watch This Week

While SPY is an index ETF, its price will respond to a steady stream of stock‑specific and macro headlines this week.

Key themes

Mega‑cap tech and AI sentiment
November saw a stark divergence between AI bellwethers: Alphabet rallied nearly 14% for the month, while Nvidia dropped about 11% on fears that Google’s custom chips could erode its GPU dominance. ^[24] Given the heavy tech weight in SPY, any reversal or continuation of this trend will heavily influence Monday’s tone.
Earnings in growth and cloud names
The coming week brings several closely watched reports in AI‑adjacent and networking stocks—for example, Credo Technology is slated to release results on Monday, December 1, after the close. ^[25] Strong or weak guidance from these names can ripple through SPY via both direct weightings and sentiment toward the broader tech complex.
Early‑December economic data
Investors will be watching:
- Manufacturing and services PMI readings
- Weekly jobless claims
- The November jobs report later in the week
  These numbers will help confirm whether the economy is gently cooling—a backdrop that has so far supported the case for rate cuts without an immediate recession, a sweet spot for SPY.
Bond yields after QT ends
On Friday, the 10‑year Treasury yield was hovering near 4%, having fallen from its peaks earlier in the year. ^[26] How yields trade once QT officially ends Monday will be central to SPY’s path, given the tight inverse relationship between long‑term rates and equity valuations all year.

7. SPY at the Opening Bell: What to Watch on December 1

Putting it all together, here’s how SPY’s setup looks into Monday’s premarket:

Trend: Uptrend intact, with SPY near all‑time highs after a strong recovery from November’s mid‑month dip. ^[27]
Sentiment: Cautiously optimistic—futures higher, volatility easing, and seasonality supportive, but flows show investors are still trimming risk into strength. ^[28]
Risk factors:
- Heavy concentration in a handful of mega‑cap tech stocks. ^[29]
- Warnings from valuation models about potential downside in 2026. ^[30]
- The possibility that economic data or Fed communications reset expectations for how quickly rates will fall.

For traders and longer‑term investors alike, Monday’s open will be less about whether SPY ticks a few dollars higher and more about how the market digests the start of a new policy phase (post‑QT), the incoming data, and the still‑dominant AI and megacap growth story.

As always, this overview is informational only and not personal investment advice. Anyone considering trading or investing in SPY should evaluate their own risk tolerance, time horizon, and financial situation, and consider consulting a qualified financial professional.
