Arista Networks (ANET) upgraded to Conviction Buy from Buy at Goldman Sachs with analyst Rod Hall seeing "significant upside potential" to consensus expectations driven by Arista's expansion into campus switching. 4. ConocoPhillips (COP) upgraded to Overweight from Neutral at Piper Jaffray with analyst Blake Fernandez attributing the stock's year-to-date underperformance to concern over major project spending risk, which he believes is embedded in current valuation levels. 5. Diplomat Pharmacy (DPLO) upgraded to Outperform from Market Perform at Raymond James with analyst John Ransom saying the 56% decline in shares since the February earnings delay provides a valuation that could be attractive to a strategic buyer.
