Sign InThis sell-off occurs as global tech giants face similar pressures, with investors closely monitoring the earnings of the 'Mag 7' to compare profit margins. Compared to the previous quarter, fears have intensified that rising CapEx may not immediately translate into bottom-line growth, dragging down sector indices per market data. Sentiment was further weighed down by global inflation data, with the UK annual inflation rate hitting 2.8% on June 17, 2026, maintaining pressure on growth-oriented stocks.
Looking at current price levels, traders are watching for stabilization in Samsung (005930.KS) and SK Hynix (000660.KS) following this volatile period (close June 23, 2026). On the macro front, investors will look toward the Federal Reserve's interest rate trajectory, which stood at 3.75% as of June 17, as a key driver for global liquidity. Additionally, upcoming US retail sales data will serve as a vital indicator to gauge final consumer demand for electronics.
