Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Clorox (CLX) upgraded to Buy from Hold at Argus with analyst John Staszak saying the company offers a "favorable growth profile and consistent record of industry outperformance," with efforts to increase revenues through innovation while conducting "low-cost operations." 2. Dollar General (DG) upgraded to Buy from Neutral at Buckingham with analyst Bob Summers saying he expects sustained operating strength through at least the second half of 2018 driven by the ongoing benefit from initiatives and investment as well a favorable consumer environment. 3. SAIC (SAIC) upgraded to Buy from Hold at Jefferies with analyst Sheila Kahyaoglu saying she is "incrementally more positive" and views the 10% pullback in shares since the Engility (EGL) deal announcement as a buying opportunity. 4. Helmerich & Payne (HP) upgraded to Buy from Neutral at B. Riley FBR with analyst Tom Curran citing valuation as well as the company's technology and super spec strategy. 5. Canadian National (CNI) upgraded to Buy from Neutral at Citi with analyst Christian Weatherbee saying he left meetings with management constructive that the "heavy lifting" of fixing the company's network and adding capacity is largely complete and should pay dividends through "robust" volume growth, greater fluidity, and lower costs. And this improvement coincides with easier comps, as Canadian National's network "was greatly stressed into the winter of last year from a surge in volume and bad weather."
