On October 13, Arista Networks fell 3.97% in Regular Trading, trading at $200.29 per share, with turnover of $148 million.

The clearest recent catalyst is continued insider selling disclosures, which have pressured near-term market sentiment despite otherwise supportive analyst targets and index inclusion.

Recent filings disclosed that CEO and director Jayshree Ullal sold shares on October 6 and October 7, including roughly 559,000 shares across those sessions, following additional sizable August sales under a Rule 10b5-1 plan. Director Andreas Bechtolsheim also reported multiple August dispositions, including about 417,000 shares under a prearranged trading plan. While several firms lifted price targets toward $250 and the company was added to the S&P 100 in September, the latest trading reaction suggests investors are focusing more on insider sales than on those positive longer-term signals.
