That’s sure an ugly decline!
Could have something to do with this:
VANCOUVER, British Columbia, Jan. 29, 2020 (GLOBE NEWSWIRE) — Silvercorp Metals Inc.’s (“Silvercorp” or the “Company”) (TSX/NYSE American: SVM) operations in China are usually suspended two weeks for the Chinese New Year holiday. During the 2020 holiday season, the Company’s production was suspended on January 17 and was scheduled to re-start on February 1. Due to the coronavirus situation, China’s central government extended the Chinese New Year holiday by three days to February 3, 2020, and as instructed by the provincial governments, the Company now expects a re-start date of February 10, 2020. The Company expects to catch-up on the lost production time with shortened holidays in the future.
