Insights

Small, pre‑planned director stock sale with limited signaling value.

Director Kelly Bodnar Battles sold 422 shares of Arista Networks common stock in multiple open‑market sales on May 21, 2026. Reported per‑share prices range from about $140.49 to around $147.93. After the trades, Battles directly holds 10,078 shares.

The filing states the sales were effected under a Rule 10b5‑1 trading plan that was entered into by the reporting person. Such plans pre‑schedule trades, so the timing of these sales typically carries less informational weight about the insider’s current view.

The transactions represent a modest portion of the reported direct holdings, suggesting a routine liquidity or diversification move rather than a major change in exposure. Subsequent company filings may provide additional context on any future transactions under the same trading plan.

4 terms

Rule 10b5-1 trading plan regulatory

"The sale of shares was effected pursuant to a Rule 10b5-1 trading plan entered into by the reporting person"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average price financial

"The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions"

Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.

open-market sale financial

"transaction_action: open-market sale; transaction_code_description: Sale in open market or private transaction"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

Form 4 regulatory

"INSIDER FILING DATA (Form 4)"

Form 4 is a official document that company insiders, such as executives or major shareholders, file with regulators whenever they buy or sell company shares. It provides transparency about how those with inside knowledge are trading, helping investors see if insiders are confident in the company's prospects or may be selling for personal reasons. This information can influence investor decisions by revealing insiders' perspectives on the company's value.
