Technical Snapshot (SPY)

Level	Sep 15	Sep 16	Sep 17	Sep 18	Sep 21
20-day SMA	764.16	763.40	762.74	762.42	762.46
50-day SMA	757.02	757.14	757.27	757.61	757.85
200-day SMA	710.74	711.18	711.57	712.00	712.44

Near-term pivot structure, based on 2026-09-18:

• Resistance: 763.09 (R1), then 764.55 (R2)
• Pivot: 760.53
• Support: 759.07 (S1), then 756.51 (S2)

SPY trend levels still lean constructive on a longer view. As of Sept. 21, the SPY 20-day SMA was 762.46, above the 50-day SMA of 757.85, and both sat well above the 200-day SMA of 712.44. Nearby traditional pivot levels from the Sept. 18 reference date show pivot support at 760.53, with resistance at 763.09 and 764.55. Short term, the bigger question is whether price strength can pull more stocks back above their moving averages.

Bottom Line

Sept. 21 brought a strong headline rebound, led by the Nasdaq and supported by better breadth than Friday. Still, with only 25.45% of stocks above their 20-day averages and the Russell 2000 lagging, the move looks improved, but not yet broadly confirmed.
