However, other markets have faced headwinds, with some, such as the S&P 500 and Germany's DAX 40, ending the week lower due to various factors including tech selloffs and sector weaknesses. The overall outlook is uncertain, with some sectors and stocks showing strength while others struggle with challenges such as rising yields and earnings misses.
