Rutherford-Darwin Portfolio Review: 11 July 2025
After the Independence Day Holiday and the break through the significant 6100 resistance level in the S&P 500 Index (SPX) we waited to see where the markets would go next – but, it was a quiet week, with consolidation around 6250 and a close just slightly lower than last week’s close:
