The S&P 500 dipped below its 200-日均线 yesterday for the first time since 2023年11月1日. That key level currently sits at 5732.91. While the index traded below it intraday, it managed to close just above at 5738.52, avoiding a more definitive breakdown.

In early trading today, price action remains volatile around this key technical level. The index is currently trading below at 5730.49, down -7分（-0.11%）. A 日线收于200日移动平均线下方 would strengthen the bearish outlook heading into the weekend.

On the downside, the next major support zone lies between 5669.67和5688.43 (yellow area and red-numbered circles on the chart). Further below, the 50%回撤 of the rally from the 2024年8月低点 stands at 5633.27, making it a key downside target if selling pressure accelerates.

If the price can rise and hold above the 200-日均线, it would signal a potential shift in momentum. A further break above the 38.2%回撤水平 of the rally from the 8月低点5754.58 would strengthen the bullish case, suggesting buyers are regaining control.

与此同时，纳斯达克指数在盘中高点上涨至158.92点后，当天走低。过去4个交易日，该价格在200日均线（18399.30）上下交易。今天的高价还没有达到让卖家保持控制的MA水平。

交易周，纳斯达克指数下跌-4.74%。标准普尔指数下跌-4.08%。
