The S&P 500 (SPX) has recently encountered resistance around the 4,300 - 4,340 level. Simultaneously, the retracement of the US 10 Year Yield and the DXY (US Dollar Index) indicates a potential upside for the SPX, with a target around 4,430 - 4,450. However, there is a cautious perspective that breaking through this level might prove challenging once again.
