Alcoa (AA) downgraded to Neutral from Buy at Citi with analyst Alexander Hacking saying the risk/reward is now evenly balanced following the stock's 35% rise since November 1. 2. Marvell (MRVL) downgraded to Sell from Neutral at Goldman with analyst Mark Delaney saying the company's key markets are in secular decline while a turnaround will be more difficult following R&D spending cuts. 3. Arista Networks (ANET) downgraded to Equal Weight from Overweight at Morgan Stanley with analyst James Faucette saying Arista's valuation reflects expected share opportunities in the data center switching market and switch-router opportunity. 4. Sotherly Hotels downgraded to Market Perform from Outperform at JMP Securities. 5. KeyCorp (KEY) downgraded to Underperform from Outperform at CLSA with analyst Mike Mayo saying Comerica (CMA) and Zions (ZION) benefit more than other large banks from higher rates, lower taxes, and exit from SIFI status, in contrast to KeyCorp which is estimated to have no benefit and has a higher valuation.
