S&P 500 Showing Pre-Market WeaknessUS SPX 500 (Mar 2026)CMCMARKETS:SPX500H2026CryptocurrencyWatchGroupPre-market price action is indicating early signs of short-term weakness, as the S&P 500 has broken below the key 6,685 level, suggesting a shift in structure before the open. After rejecting the 6,700ā6,716 resistance zone (0.618 Fibonacci level), price has moved lower and is now trading beneath prior support a level Iām watching as potential resistance if retested. From my analysis, momentum is beginning to turn bearish, with lower highs forming under a descending trendline. š Key levels Iām watching ā¢ Resistance: 6,685ā6,700 ā¢ Immediate support: ~6,625 ā¢ Lower support zone: ~6,600 If price fails to reclaim 6,685, I expect continued downside pressure into lower support levels. A strong move back above 6,700, however, would invalidate this short-term bearish setup. This type of pre-market structure often sets the tone for the session, especially when key levels are lost before the open.
