Goldman Sachs analyst Heather Bellini last night downgraded Zoom Video Communications (ZM) to Sell from Neutral while raising her price target for the shares to $66 from $53.

The stock closed Friday down $1.48 to $88.79.

The analyst says her "blue sky scenario" is already more than factored into investor expectations at current valuation levels. Bellini, however, adds that her view on Zoom Video's ability to continue to execute well and exceed consensus expectations remains unchanged. Nonetheless, the potential for long-term performance is well understood by the market, contends the analyst.

Bellini last night also downgraded SolarWinds (SWI) to Sell from Neutral and upgraded Anaplan (PLAN) to Buy from Neutral.
