Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Owens Corning (OC) upgraded to Outperform from Neutral at Wedbush with analyst Al Kaschalk saying the company's second-half 2017 results should be helped by improving weather, rebounding inflation, improved housing and industrial markets versus last year, and recent major storms. 2. Alcoa (AA) upgraded to Outperform from Market Perform at BMO Capital with analyst David Gagliano citing what he sees as "the recent disconnect" between "solid aluminum and alumina prices" and "soft Alcoa shares." He thinks that these trends have created "a solid buying opportunity." 3. CME Group (CME) upgraded to Outperform from Underperform at RBC Capital with analyst Peter Lenardos saying he expects supportive volume levels with growth of 7% in 2017 versus consensus of 5% and benefits from regulatory tailwinds and tax policy. 4. ArcelorMittal (MT) upgraded to Overweight from Neutral at JPMorgan with analyst Roger Bell citing relative valuation. The analyst believes the company's higher U.S. exposure relative to European Steel peers will become an advantage over the remainder of the year. He raised his price target for the shares to EUR 10 from EUR 7.80. 5. CIBC (CM) upgraded to Neutral from Underperform at Credit Suisse. This list is just a portion of The Fly's full analyst coverage.
