S&P 500 (ES) Analysis, Key-Zones, Setup for Fri (Oct 23)E-mini S&P 500 FuturesCME_MINI:ES1!MyAlgoIndexBias: The December S&P 500 contract settled at 7,704.50 on Thursday, down 95.75 or 1.23 percent, ending a run of three consecutive higher settles with its largest one-day point decline since 07/29. The session traded between 7,798.75 and 7,676.75, a 122.00 point range with a lower high and a lower low against Wednesday, the widest since 10/16, and the settle finished 22.75 percent of the way up from the low. The S&P 500 cash index closed at 7,663.43, down 1.21 percent, as the Nasdaq-100 fell 2.90 percent and semiconductor shares 6.72 percent, while the Dow industrials and the NYSE composite closed slightly higher, so the decline was concentrated in large technology shares. The news feed carried items on Meta's future spending commitments rising to 825 billion dollars and on its credit risk gauge reaching a fresh high, and its market wraps described doubts over returns on heavy artificial-intelligence investment alongside escalating Middle East tensions. The ten-year yield index fell to 4.95 percent and the volatility index rose to 19.03 from 16.68. The reopened session quoted the contract at 7,709.25 at about 6:31 PM ET, 4.75 points above the settle. The settle sits beneath the 5-day through 50-day settlement averages and above the 100-day and 200-day, negative direction leads on the 9-day and 14-day directional systems, and the composite multi-indicator read slipped to hold from 40 percent buy. In this review's interpretation the bias is neutral to lower beneath two standard deviations resistance at 7,761.20, with the broad market's resilience the main evidence against it. The cash close sits beneath the modeled gamma-flip level at SPX 7,712 and the modeled volatility threshold at SPX 7,760, and beneath the desk pivot at SPX 7,690, which in this review's interpretation leaves dealer hedging less likely to dampen moves. The US flash purchasing managers' surveys are listed at 9:45 AM ET Friday on the news-feed calendar, unconfirmed. In this review's interpretation the first-order influence on Friday is whether Thursday's technology selling extends, with a weekend to follow the close. Resistance: - 7,798.75 Thursday's session high (SPX 7,757.68) - 7,776.58 Pivot R1 (SPX 7,735.51) - 7,773.95 three standard deviations resistance (SPX 7,732.88) - 7,764.47 9-day average crossing price (SPX 7,723.40) - 7,761.20 two standard deviations resistance (SPX 7,720.13) - 7,758.60 38.2 percent retracement from the four-week low (SPX 7,717.53) - 7,744.60 one standard deviation resistance (SPX 7,703.53) - 7,726.67 Pivot Point (SPX 7,685.60) - 7,706.74 38.2 percent retracement from the 13-week high (SPX 7,665.67) Support: - 7,703.97 published target price (SPX 7,662.90) - 7,676.75 Thursday's session low (SPX 7,635.68) - 7,672.75 one-month low (SPX 7,631.68) - 7,664.40 one standard deviation support (SPX 7,623.33) - 7,654.58 Pivot S1 (SPX 7,613.51) - 7,647.80 two standard deviations support (SPX 7,606.73) - 7,635.05 three standard deviations support (SPX 7,593.98) - 7,604.67 Pivot S2 (SPX 7,563.60) Primary Setup: SHORT the December contract from the 7,740 to 7,748 band (SPX 7,698.93 to 7,706.93) around one standard deviation resistance at 7,744.60. Stop 7,764 (SPX 7,722.93), above two standard deviations resistance at 7,761.20 and the 38.2 percent retracement at 7,758.60. Targets at 7,724 first (SPX 7,682.93), beneath the Pivot Point at 7,726.67, 7,704 second (SPX 7,662.93), just beneath Thursday's 7,704.50 settle, and 7,684 third (SPX 7,642.93), above Thursday's 7,676.75 low. Risk to reward is roughly 1:1 to the first objective, 1:2 to the second and 1:3 to the third from the entry midpoint. The 14-day average true range is 82.92 points against a 20 point stop distance. A settle above two standard deviations resistance at 7,761.20 negates the thesis; two consecutive 30-minute closes above 7,748 remove the edge before the stop is reached. The reopened-session quote sits beneath the entry band, so the setup needs a rebound to engage. A broad reversal in technology shares is the main risk to a short, which makes this an analyst judgment that rallies are sold while technology leadership is under pressure. SPX equivalents use this run's measured 41.07 point basis. The 7,704.50 settle sits in the lower quarter of the widest range since 10/16, 27.75 points above Thursday's low. In this review's interpretation Friday is a test of whether rebounds toward one standard deviation resistance at 7,744.60 meet sellers, with Pivot S1 at 7,654.58 the line between consolidation and an extension toward Pivot S2 at 7,604.67.
