All eyes are on South Korea as tech shares continue to be battered amid the AI boom and bust cycle. While not being all too tech-heavy, European futures are also pointing lower with DAX futures down 0.7% and CAC 40 futures down 0.6% on the day. And the mood music is also not helped by the continued selloff in US tech shares after the nervous struggle from recent weeks. That culminated with another big selloff last week as investors were hit by Google posting its first ever quarter with negative free cash flow as a public company. And today is going to be a big day with a series of challenges set to test the market.
