Key Takeaways

  • The S&P 500 closed at 7,623.68 on 23 October 2026, down 0.52% on the day and 0.47% on the week. 1
  • The S&P 500 fell 1.21% on 22 October even as 337 of its 500 components rose and the equal-weight index gained about 0.8%. 2
  • As of 09:44 (GMT+8) on 26 October 2026, the Vantage SP500 contract for difference (CFD) traded at 7,630.03, below its 50-period and 200-period moving averages on the hourly chart.

The S&P 500 fell 35.76 points, or 0.47%, last week to close at 7,623.68, yet the Russell 2000 of smaller US companies gained about 2% over the same five sessions. 1 Both indices faced the same Fed and the same oil price. The gap traced back to a small group of very large artificial intelligence (AI) stocks, and three of them report results this week.

That split is the S&P 500 news worth unpacking today: why a market-value-weighted index can fall while many of its members rise, what the hourly S&P 500 chart shows, and how the risk picture shifts into the Federal Reserve decision and Big Tech earnings on 28 and 29 October (US time). For anyone holding an S&P 500 CFD, the point is practical. The instrument tracks the weighted index, so its exposure leans on those few names rather than on the average stock.

As of 09:44 (GMT+8) on 26 October 2026, Vantage SP500 CFD traded at 7,630.03, roughly flat on the hour, after an early Asia-session bounce toward 7,668 faded. The cash index closed 2.50% below its 6 October record close of 7,818.93. 3 Year to date, the S&P 500 is up 11.37%, a gain of 778.18 points. 1

AI Financing Worries Hit the Heaviest Names

The heaviest session of the week came on 22 October, when the S&P 500 fell 1.21% and the Nasdaq Composite dropped 2.60%, its steepest daily fall since June. 4 The reporting pointed to Meta Platforms (NASDAQ:META), whose shares fell nearly 7% after it raised its 2026 capital spending floor to $135 billion and created a non-voting share class to raise money. 5

Meta also burned about $2.1 billion of cash in the quarter, its first negative quarter in more than a decade, and chip stocks sank about 6.7% the same day. 5 Chip-equipment maker Lam Research (NASDAQ:LRCX) added to the pressure after flagging supply constraints. 4 Revenue beat estimates; the cash-flow line drew the attention.

Higher AI spending is revenue for chipmakers, so the chip slide needs explaining. The concern was financing: investors questioned how much debt-funded AI spending can keep paying for itself, and moved out of technology and communication services into defensive sectors and US Treasuries, Investing.com reported. 6

Friday brought a different weight. Rising oil prices pressured most sectors, the Dow Jones Industrial Average fell 1.23%, and the S&P 500 slipped 0.52%. 7 The Cboe Volatility Index (VIX) rose to 20.24 on Friday, after a jump of about 14% the day before. 7

That explains why the index fell. The hourly chart shows how the slide unfolded, and where it paused.

S&P 500 Chart Shows Lower Highs, Firmer Momentum

SP500_2026-10-26_09-44-07
Figure 1: SP500 H1 “Lower swing highs since 21 October, price below the 50- and 200-period moving averages, RSI 40.55” (TradingView) Accessed on 26 October 2026. Data indicative, for informational purposes only.

On the Vantage SP500 CFD hourly (H1) chart, price peaked near 7,776 on 21 October and printed lower swing highs after that: a rebound high near 7,707 on 22 October, near 7,680 on 23 October, and near 7,668 in early Monday trade (GMT+8). As of 09:44 (GMT+8) on 26 October 2026, price sat below the faster 50-period moving average at 7,671.46 and the slower 200-period average at 7,722.75.

Both averages sloped lower at the cut-off, with the 50-period line beneath the 200-period line. That alignment describes a short-term downtrend already in place. It says nothing about how long it lasts.

Momentum reads differently. The 14-period Relative Strength Index (RSI) on the TradingView setup used for this analysis read 40.55 at the cut-off, just under its signal line at 41.41. When price fell to a low near 7,641 on 22 October, RSI was around 30. When price slipped to a lower low near 7,617 on 23 October, RSI held around 35.

Price made the lower low; momentum did not. An RSI near 40 is the indicator’s version of a shrug.

A chart of the index can only show the total. It cannot show which stocks dragged it lower.

The Average S&P 500 Stock Rose

The 22 October session shows the split most clearly. The S&P 500 Equal Weight Index rose about 0.8% while the standard index fell 1.21%, and 337 of 500 components closed higher, Schwab noted. 2 Schwab counted it as one of only five days since 1996 on which advancers outnumbered decliners by more than 100 while the index fell more than 1%. 2

Across the full week, the equal-weight S&P 500 rose about 1.1% while the standard index fell 0.47%, according to Atrani Capital. 8 In the week to 16 October, the equal-weight index rose 1.58% while the standard index fell 1.95%, according to Navellier. 9

Sector returns show the same split. Energy and consumer staples each gained more than 10% in October, while information technology and communication services each fell more than 5%, CNBC reported. 7 An S&P 500 index that excludes AI-linked companies was up about 12.4% for 2026 at the 22 October close, slightly ahead of the full index’s gain of roughly 12%. 7

The mechanism is the weighting. The S&P 500 weights each company by its float-adjusted market value, so the largest names move the index most. In plain terms, a few heavy AI stocks on one side of the scale outweighed hundreds of smaller gains on the other.

That changes what SP500 CFD exposure means this week. It is less exposure to the average US company than exposure to how investors price the spending plans of the index’s largest technology firms, and three of them report within about 24 hours of each other.

The S&P 500 fell 0.47% last week while its equal-weight version rose about 1.1%. The gap came from the index’s heaviest AI-linked names.

Whether that gap narrows or widens now depends on a calendar that squeezes a Fed decision and three earnings reports into two days.

S&P 500 Futures Head Into the Fed and Big Tech

S&P500 outlook with oil, rates and Trump-Xi summit catalysts

S&P 500 futures edged about 0.2% higher in early Sunday trade as oil eased and investors rotated away from the AI trade, Bloomberg reported. 10 On the Vantage chart, that early bounce had faded by the Asia morning.

The Federal Open Market Committee (FOMC) meets after the Fed raised rates in September. 11 The CME FedWatch Tool put the probability of another hike this week at 9% and of one by December at 84%, according to Yardeni Research. 12 Markets are pricing a hold now and a hike later, and the press conference is where that pricing gets tested.

What to Watch

All times are converted to GMT+8; the full list sits in the economic calendar.

  • FOMC Decision, 29 October 2026, 02:00 (GMT+8): The statement lands at 14:00 Eastern Time (ET) on 28 October, followed by Fed Chair Kevin Warsh’s press conference. 12
  • Microsoft and Alphabet Results, 29 October 2026, From About 04:00 (GMT+8): Microsoft (NASDAQ:MSFT) and Alphabet (NASDAQ:GOOGL) report after the US close on 28 October, hours after the Fed. 13 For readers in GMT+8, both land before breakfast.
  • US Q3 Growth and September Inflation Data, 29 October 2026, 20:30 (GMT+8): The Bureau of Economic Analysis (BEA) publishes its advance gross domestic product (GDP) estimate at 08:30 ET. 14 September personal income and outlays, which include personal consumption expenditures (PCE) inflation, are released at the same time. 15
  • Amazon Results, 30 October 2026, From About 04:00 (GMT+8): Amazon (NASDAQ:AMZN) reports after the US close on 29 October. 11

SP500 CFD Levels Traders Are Watching, as of 09:44 (GMT+8) on 26 October 2026

Levels read from the Vantage SP500 CFD H1 chart on TradingView at 09:44 (GMT+8) on 26 October 2026. Neutral reference levels only, not trade signals.

The lower-high read weakens if price recovers above the 50-period average and the 7,680 to 7,707 band of recent rebound highs. It holds while price stays beneath that band. A move below 7,617 with RSI also making a new low would remove the momentum divergence described above.

Last week ended with the index down and the average stock up. That split has not resolved, and this week the companies on the heavy side of the scale report their own numbers, with a Fed decision in between.

Overnight Earnings Raise Gap Risk

Microsoft, Alphabet, and Amazon all report after the US cash close, so the first price reaction arrives in thinner extended trading and can carry into the Asia session. Prices can gap through a level in those conditions. A Stop Loss can help limit a loss to a size set in advance, although it cannot guarantee execution at that exact price when the market gaps.

Leverage magnifies gains and losses equally. At 1:20, for example, a 1% move in the S&P 500 equals about 20% of the margin committed to the position, in either direction. Sizing exposure as a fixed share of account equity, rather than around a view on one evening’s results, is one way traders keep a single event from carrying outsized weight.

Tickers, Futures, and Tomorrow’s Close

What is the S&P 500 ticker?

The cash index is commonly quoted as SPX, and the CME E-mini futures contract as ES. An S&P 500 index fund carries its own ticker, such as SPY, IVV, or VOO, and Vantage lists the index CFD as SP500. One index, several name tags.

How do S&P 500 futures relate to the S&P 500 today?

S&P 500 futures trade almost around the clock, so they show how the market prices the index outside US cash hours. That is why an S&P 500 live quote on a CFD chart can move during the Asia session, as Vantage SP500 CFD did early on 26 October (GMT+8).

Can anyone predict where the S&P 500 trades tomorrow?

No method reliably predicts tomorrow’s close, so any stock prediction for tomorrow is an opinion. Markets do publish pricing, such as FedWatch probabilities, consensus earnings estimates, and futures quotes, and questions about the future of the S&P 500 usually come back to how outcomes compare with that pricing.
