Arista Networks Inc (NYSE:ANET) shareholders have seen the share price descend 25% over the month. But over five years returns have been remarkably great.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Over half a decade, Arista Networks managed to grow its earnings per share at 26% a year. This EPS growth is lower than the 49% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. That's not necessarily surprising considering the five-year track record of earnings growth.
