The S&P 500 futures ($ES_F) experienced a significant reversal on September 11, 2024. The index tested its 50-day moving average, broke out of its recent trading range to the upside, and closed just below the 20-day moving average. This bullish price action followed a defense of the 100-day moving average. Market analysts noted the powerful breadth and price reversal, particularly around key $SPY and $QQQ open interest strikes. The poor high above looms large, and tomorrow will reveal if there's continuation.
