Arista Networks, Inc. (NYSE:ANET) shareholders might be concerned after seeing the share price drop 19% in the last month. But that doesn't change the fact that the returns over the last three years have been very strong. In three years the stock price has launched 209% higher: a great result. So the recent fall in the share price should be viewed in that context. The thing to consider is whether the underlying business is doing well enough to support the current price.

Since the long term performance has been good but there's been a recent pullback of 9.3%, let's check if the fundamentals match the share price.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During three years of share price growth, Arista Networks achieved compound earnings per share growth of 47% per year. Notably, the 46% average annual share price gain matches up nicely with the EPS growth rate. This observation indicates that the market's attitude to the business hasn't changed all that much. Quite to the contrary, the share price has arguably reflected the EPS growth.

A Different Perspective

It's nice to see that Arista Networks shareholders have received a total shareholder return of 58% over the last year. That gain is better than the annual TSR over five years, which is 25%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
