How to Read AMS Insider Activity
Net insider activity is balanced over the trailing twelve months: 0 buys against 0 sales. Balanced activity typically reflects routine compensation-related vesting and tax-driven liquidity rather than directional information signals. 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 AMS insider trading questions
- How active are AMS insiders right now?
- Over the trailing twelve months, American Shared Hospital Services (AMS) insiders made 0 buy transactions and 0 sale transactions. Net insider activity over the trailing twelve months is balanced (0 buys, 0 sales). 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 AMS insider buys a bullish signal?
- Insider open-market purchases (Type P) 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 AMS 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.
