ATER Insider Activity by Quarter

Reported Form 4 and Form 5 lines under ATER's own SEC company ID, by transaction date, back to Q4 2024.

Later filings and amendments can change the current quarter. Earlier quarters are not shown: the filings read reach back to Jun 12, 2019, and a quarter counts only when every filing for it was read. 2 lines filed under another SEC company ID are not counted.

From the SEC's Form 13F data sets: investment managers with $100 million or more in Section 13(f) securities report their holdings each quarter, up to 45 days after it ends; a restated filing replaces the original, and values are as the managers reported them (a position whose price runs about 1,000 times below other managers', from a manager whose positions mostly do, is read as reported in thousands of dollars). The same shares can be reported by more than one manager, so totals can count some twice.

How to Read ATER Insider Activity

Net insider sentiment skews to the sell side over the trailing twelve months: 2 sales versus 0 buys. Insider sales carry less informational weight than buys because they are often driven by liquidity, tax planning, or pre-scheduled Rule 10b5-1 trading plans rather than negative information. The transaction type alone does not say whether a sale was made on the open market or privately, or under a 10b5-1 plan; the filing's plan checkbox and footnotes do. The transaction table above includes the filer's reporting name, transaction type, share count, per-share price, and total dollar value where computable. For options traders, insider activity is one input to event-driven sizing alongside earnings calendar, analyst-rating cluster moves, and the implied-vol surface. Form 4 filings (the dominant Section 16 reporting form) must be submitted within two business days of the transaction; clusters of buys across multiple insiders within a short window are the strongest informational pattern. SEC EDGAR carries the underlying source filings for verification and additional historical depth.

Frequently asked ATER insider trading questions

How active are ATER insiders right now?
Over the trailing twelve months, Aterian, Inc. (ATER) insiders made 0 buy transactions and 2 sale transactions. Net insider sentiment over the trailing twelve months tilts to the sell side (2 sales vs 0 buys). The transaction list above shows the most recent filings; each entry includes the insider's name, transaction type, share count, and per-share price.
What counts as an insider transaction?
Section 16 of the Securities Exchange Act requires officers, directors, and 10% beneficial-owner shareholders to disclose changes in their holdings via Form 3 (initial statement), Form 4 (subsequent transactions, filed within two business days), and Form 5 (annual catch-up). Insider transactions cover open-market purchases and sales, exercise of stock options, gifts, and grants. The "transaction type" field on each row distinguishes these subcategories.
Are ATER insider buys a bullish signal?
Insider purchases (Type P, made on the open market or privately; the code covers both) carry more informational weight than insider sales: an insider must commit personal capital, and the SEC scrutinizes purchases under Rule 10b5-1 for material non-public information. Sales, by contrast, are often driven by liquidity, tax planning, or pre-scheduled 10b5-1 trading plans rather than negative information. Cluster buying (multiple insiders buying within a short window) is a stronger signal than isolated buys.
How do ATER insider transactions affect options pricing?
Insider transaction data does not directly drive implied volatility, but Form 4 disclosures can move single-name IV if the size or timing is unusual (e.g. a large CEO buy ahead of an earnings window). Options markets price the marginal informational content; routine transactions under pre-scheduled plans are typically ignored. For event-driven options sizing, pair the insider transaction history with the upcoming earnings calendar.
