Samsung and rivals SK Hynix Inc. and Micron Technology Inc. are weathering a cyclical downturn, helped by demand from servers as well as a widening array of products from cars to home devices. Micron last month predicted record revenue for fiscal 2022 thanks to resilient demand from data centers, networking and auto customers. Investors are also monitoring Samsung's operation in the central Chinese city of Xi'an, which has been locked down while the government fights a local outbreak. While it's unclear how long that situation will persist in the city -- also a big Micron production center -- analysts say short-term disruptions might dampen supply and lift chip prices. Samsung will provide net income and divisional performance when it reports its full earnings on Jan. 27. "Memory prices will rebound in the second quarter if the lockdown in Xi'an gets prolonged," said CW Chung, head of Asia technology at Nomura Financial Investment.
