Catch up on today's top five analyst downgrades with this list compiled by The Fly: 1. Enduro Royalty (NDRO) downgraded to Sell at Stifel with analyst Brian Brungardt, Jr. saying he believes Enduro Royalty will suspend its distribution given the lag in production and that it will underperform peers after such a suspension. 2. Avista (AVA) downgraded to Sell at UBS by analyst Julien Dumoulin-Smith, who said the company's 10% valuation premium to small/medium cap regulated utility peers is unsustainable. 3. Kennametal (KMT) downgraded to Underperform at Longbow with analyst Eli Lustgarten citing continued weak end markets with potential further deteriorating stemming from energy market volatility and ongoing weakness in US industrial production. 4. iRobot (IRBT) downgraded to Underweight at JPMorgan by analyst Mark Strouse, who said the shares are now pricing in "near-flawless execution of international expansion," presenting an unfavorable risk/reward. 5. Banco Santander (SAN) downgraded to Sell at Societe Generale due to decreasing profitability in key markets that may put the company's fully-loaded Core Tier 1 ratio target at risk.
