4 terms
Rule 10b5-1 trading plan regulatory
"The sale of shares was effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on March 13, 2026."
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 reported price in Column 4 is a weighted average price."
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""
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.
indirect ownership financial
"ownership_type: "indirect" and nature_of_ownership: "By spouse""
FAQ
Was the Natera (NTRA) insider sale made under a Rule 10b5-1 plan?
Yes. A footnote states the share sales were effected under a Rule 10b5-1 trading plan adopted by Matthew Rabinowitz on March 13, 2026. Such plans pre-schedule trades, reducing the significance of short-term market timing.
What is the nature of the Natera (NTRA) indirect holdings reported in this Form 4?
The Form 4 lists an indirect holding of 5,000 Natera shares classified as held "By spouse." This indicates those shares are owned through his spouse rather than in Rabinowitz’s direct name, but are still reported for beneficial ownership.
