Rule 10b5-1 trading plan regulatory
"Sales effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on December 3, 2025."
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.
bona fide gift regulatory
"transaction_code_description: "Bona fide gift" for the 20,000-share gift transfers."
A bona fide gift is a genuine, voluntary transfer of money, property, or benefits from one party to another made without expectation of repayment, services, or hidden conditions. Investors care because such gifts can affect company disclosures, related‑party transaction rules, tax treatment, and perceived conflicts of interest; think of it like someone giving you a present with no strings attached — but on a corporate scale, auditors and regulators need to verify it really is unconditional.
weighted average price financial
"Reflects the weighted average price of 900 shares of common stock of Aeluma, Inc. sold by the reporting person 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.
family trust financial
"nature_of_ownership: "By Family Trust" for the indirect 20,000-share gift transaction."
open-market sale financial
"transaction_action: "open-market sale" for the non-derivative sales of common stock."
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.
