Micron rises after SK Hynix earnings; Samsung results next test

Micron shares rose more than 4% after SK Hynix's upbeat earnings and outlook, which projected the memory shortage will persist through 2030. SK Hynix also announced a roughly $75 billion shareholder-return program. Micron is expected to launch its own buyback program in December. Samsung's results, due Wednesday, are the next major test for the memory-chip trade.
