Catch up on the today's top five analyst upgrades with this list compiled by The Fly: 1. Dover (DOV) upgraded to Outperform from Market Perform at Bernstein with an $87 price target. The firm thinks that the oil-related headwinds the company had been experiencing have peaked. It says that the company's non-oil business now accounts for 93% of its earnings, up from about 60% previously, and Bernstein expects those units to generate low to mid single digit percentage organic growth. Additionally, the firm is extremely upbeat on the company's acquisition of Wayne, saying that the deal increases the value of Dover's stock by $7 per share. 2. Joy Global (JOY) upgraded to Outperform from Market Perform at FBR Capital by analyst Lucas Pipes, who also raised its price target for shares to $25 from $14. The analyst has increased confidence Joy's growth opportunities following its strategic wins in India and the Canadian oil sands and notes the company's organic order rate is tracking well against his estimates. 3. Ducommun (DCO) upgraded to Buy from Hold at Canaccord, which raised its price target to $23 from $19 on Ducommun shares. The firm cited better visibility, execution and de-leveraging of its balance sheet. The recent divestitures are expected to significantly contribute to improved margins, the firm said. 4. Pentair (PNR) upgraded to Buy from Neutral at Seaport Global by analyst Ryan Cassil, who raised his price target to $70 from $59. The analyst believes the worst margin performance is behind the company in its V&C segment and has increased confidence in management's forecast for decrementals to be reduced by half in Q2 as volumes increase seasonally and high-cost inventory is turned. 5. U.S. Concrete (USCR) upgraded to Buy from Neutral at Sidoti by analyst Michael Conti, who raised his price target to $90 from $72. The analyst views the capital raise from debt refinancing as a catalyst for acquisitions. This list is just a portion of The Fly's full analyst coverage.
