Ryder System Inc. said it will buy back up to 15% of its stock and is considering selling four subsidiaries to refocus on its transportation businesses. Ryder stock rose $1.125 to $28.125 after the announcement. The Miami-based firm expects to net more than $100 million by selling units that represent less than 5% of its assets, Ryder’s chairman said. Those are likely to include subsidiaries that handle insurance, customs brokerage, distribution and freighting, the company said, adding that it did not expect to eliminate any jobs.
