Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. FairPoint (FRP) upgraded to Buy at Drexel Hamilton by analyst Barry Sine, who said the company is back on track following better than expected Q1 results. The analyst said broadband subscriber growth turned positive and the company is close to a return to pre-strike subscriber levels and residential phone lines posted their smallest decline since the company acquired Verizon's northern New England landline business in 2007. 2. Continental Resources (CLR) upgraded to Strong Buy at Raymond James with analyst John Freeman saying Continental offers attractive leverage to the turn in oil prices with its exposure to Mid-continent resource plays and its peer-leading Bakken position. 3. Essex Property Trust (ESS) upgraded to Outperform at Raymond James by analyst Buck Horne, who believes concerns over a slowing California/tech-sector job growth and new supply in certain submarkets are overdone. 4. Parsley Energy (PE) upgraded to Strong Buy at Raymond James with analyst John Freeman saying the company has some of the most economic acreage in the country and believes shares still have room to run before it reflect the full potential of the asset base. 5. NXP Semiconductors (NXPI) upgraded to Buy at Goldman by analyst Toshiya Hari, who said above-industry growth and cost synergies from the Freescale (FSL) acquisition will drive the stock higher.
