Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. SolarWinds (SWI) downgraded to Sell from Neutral at Goldman Sachs with analyst Heather Bellini saying while the company's valuation, on an absolute basis, does not appear "overly expensive," the shares have "limited possibility" for multiple expansion given its end market exposure and already best in class operating margins. 2. SM Energy (SM) downgraded to Underweight from Equal Weight at Barclays with analyst William Thompson saying while the company's high leverage provides "oil beta with arguably premier Midland acreage," continuous drilling obligations could restrict it from pivoting away from the Eagle Ford condensate. 3. Zoom Video (ZM) downgraded to Sell from Neutral at Goldman Sachs with analyst Heather Bellini saying her "blue sky scenario" is already more than factored into investor expectations at current valuation levels. 4. Carnival (CCL) downgraded to Hold from Buy at Berenberg with analyst Stuart Gordon saying the company appears to be "finely balanced between a deteriorating operating performance and a cheap valuation." 5. Yum! Brands (YUM) downgraded to Underperform from Neutral at Longbow with analyst Alton Stump saying the stock is trading at nearly a 25% premium to its closest quick-service peers despite similar comp growth, unit growth and leverage.

Citi lowered the firm's price target on Yum! Brands to $162 from $166 and keeps a Buy rating on the shares ahead of the Q1 report. The analyst expects Yum continues to voice confidence in 5% unit growth, and its digital initiatives are growing sales for franchisees. The firm views the company's near-term outlook as "shakier" than the long-term.
