The primary Wholesale Direct Metals complaint about recent market reporting is apparent in today’s news. General Motors is laying off 1,100 workers in Michigan — the fourth layoff it’s announced since November. The company is eliminating the third shift at its Lansing Delta Township plant, which makes three SUVs built on the same platform — the Chevrolet Traverse, the Buick Enclave and the GMC Acadia. But the new version of the Acadia is being built on a smaller platform, so production of that car moved to a Spring Hill, Tenn., plant last summer. The latest Wholesale Direct Metals review of the markets is consistent with this new data.
