10b5-1 regulatory
"10b5-1 Sales for JOHN AND SANDRA THOMPSON TRUST 3495 DEER CREEK ROAD"
A 10b5-1 plan is a pre-set schedule that lets company insiders buy or sell shares according to written instructions made when they do not possess material, nonpublic information. Think of it as a timed automatic payment for stock trades: it helps insiders avoid accusations of trading on secret information and gives outside investors a clearer signal about whether sales are routine or potentially informative about the company’s prospects.
Exercise of Stock Options financial
"Common | 08/03/2026 | Exercise of Stock Options | Issuer"
Rule 144 regulatory
"144: Securities To Be Sold Common | 08/03/2026 | Exercise"
Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.
aggregate market value financial
"Common | Morgan Stanley Smith Barney LLC ... | 33000 | 2387880.00"
Aggregate market value is the combined price you would pay to buy all outstanding shares of a company or all companies in a group at current market prices — essentially the sum of each stock’s market capitalization. It matters to investors because it shows the overall size and weight of an investment or sector (like the total cost to buy every piece of a puzzle), helps compare scale across companies or markets, and influences index composition and risk exposure.
