Catch up on today's top five analyst upgrades with this list compiled by The Fly: 1. Target (TGT) upgraded to Overweight from Equal Weight at Barclays with analyst Matthew McClintock saying Target is taking market share from a "much weaker" retailer subset than other positive traffic retailers. 2. Sprouts Farmers Market (SFM) upgraded to Buy from Hold at Deutsche Bank. 3. American Airlines (AAL) upgraded to Buy from Hold at Deutsche Bank with analyst Michael Linenberg saying American's lowering of its earnings guidance range last week was not unexpected given the recent rise in fuel prices and grounding of its MAX fleet. The analyst thinks the resetting of expectations by management establishes a "floor" for American's share price and provides the company a bit more "cushion" around its earnings targets. 4. Colgate-Palmolive (CL) upgraded to Neutral from Underweight at JPMorgan with analyst Andrea Teixeira saying the company's organic growth is "finally starting to show consistent improvement," despite mixed signals from most recent scanner data in the U.S. 5. Adobe (ADBE) upgraded to Overweight from Equal Weight at Morgan Stanley with analyst Keith Weiss saying his field work, meetings with management and analysis of segment contribution margins have boosted his confidence in Adobe's ability to sustain EPS growth of over 20%, even if he assumes decelerating Digital Media growth.
