Today’s biggest moves
SK Hynix soared 13% in its record-breaking $26.5 billion Wall Street debut, while EquipmentShare surged 17% after raising its 2026 outlook. WD-40 Company climbed 11% on strong third-quarter results, and Meta Platforms extended its gains, taking it to a 15% increase in the past week and making it the top Magnificent Seven performer today.
What this means for investors
Major U.S. indexes climbed today as traders looked past tensions in the Middle East and prepared for the upcoming earnings season. SK Hynix began trading on the Nasdaq, marking the largest foreign IPO to date. Competitors such as Micron Technology slipped as the new entrant took market share. However, comments from SK Hynix Chief Executive Officer Kwak Noh-Jung suggest potential resilience in the sector — he believes memory-chip shortages will persist beyond 2030.
Another optimistic signal is that a record number of tech insiders have bought their own stock over the past six months, reflecting internal confidence even as investors are becoming cautious about high levels of AI capital expenditure.
