NEW YORK (TheStreet) -- Arista Networks (ANET) shares are sliding because the company offered conservative guidance for its current quarter, said TheStreet's Jim Cramer, portfolio manager of the Action Alerts PLUS portfolio, on CNBC's "Stop Trading" segment.
Investors chose to focus on that guidance instead of the company's ability to beat analysts' estimates for earnings per share and revenue for its latest quarter. The company's sales grew 53% year over year.
The stock is down $3.35, or 4.9%, at $65.56 at about 11:40 a.m. EDT Friday.
Cisco Systems (CSCO) has been trying to "bury" Arista Networks, as the latter had been taking market share, Cramer said. Arista Networks has some impressive clients and a very good partnership with Microsoft (MSFT), he added.
The company is an "interesting disruptor," and CEO Jayshree Ullal is a great executive, Cramer concluded.
