Chip shares keep sliding: Seoul’s Kospi sinks more than 5%, the ASX ends about flat, and Wall Street’s banks report into a bond rout
Technology and memory-chip shares extended a global sell-off on Tuesday. AP reported that South Korea’s Kospi sank more than 5% on a semiconductor sell-off tied to worries about the AI boom, and Bloomberg said Samsung Electronics and SK Hynix fell on concerns about Chinese rivals and a stretched AI rally. Reuters reported Asian stocks diving on AI jitters ahead of US bank earnings. Monday’s US session was mixed near a record, with the Dow higher and the S&P 500 struggling (AP, AFR), and Bloomberg said a chipmaker sell-off weighed on sentiment. Market Index reported the ASX 200 recovering to flat on Tuesday, with banks lifting and AI and lithium stocks tumbling. Reuters reported JPMorgan missing profit estimates, Goldman Sachs beating them, Citigroup topping them and Wells Fargo reporting a rise in profit; those were intraday events, not a close.
The AI boom has carried share markets for months, so a sharp turn in memory-chip stocks tests whether that support holds. Rising bond yields add a second pressure, because they raise the return investors demand from shares and the cost of borrowing for banks and firms.
If you hold super or shares through an index fund, you are exposed to both the AI trade and the bond move even if you own no chip stocks. Nothing here is advice to buy or sell; the point is that one-day moves tell you little.
The sell-off is a healthy correction of an AI rally that had run ahead of earnings, and bond funds taking record inflows suggest investors see value in yields.
Rising yields, a chip rout and a mixed bank-earnings start together look like the stress the IMF warned about, and the risk is a disorderly spike rather than an orderly repricing.
We would not read a day’s numbers as a verdict. We have no confirmed closing levels from two sources, so we quote none. The signals to watch today are whether the Kospi steadies, whether the ASX follows Wall Street’s chip stocks down, and whether yields stop rising.
