## Questions

### What dataset drives FFSTOCK's investment process?

The firm relies exclusively on SEC Form 4 filings — the legally mandated disclosures that corporate insiders (officers, directors, and 10% beneficial owners) submit when they trade their company's stock. FFSTOCK's platform parses these filings, filtering for transactions that exceed minimum dollar thresholds and show clustering among multiple insiders within a compressed window. The dataset is public, but the firm's signal-extraction layer applies multi-factor screens to isolate the subset of filings where the academic evidence for predictive power is strongest.

### How does FFSTOCK differentiate between routine insider sales and genuinely informative transactions?

The firm's conviction-scoring model weighs several variables: whether the transaction is an open-market purchase rather than a sale or option exercise, the dollar magnitude relative to the insider's existing holdings, whether multiple insiders are buying in the same window, and the insider's historical signal accuracy. Routine 10b5-1 plan sales are largely screened out. The system also differentiates between C-suite officers, directors, and large shareholders, assigning different weights based on empirical information-asymmetry research.

### What is the academic basis for an insider-transaction strategy?

The anomaly has been documented since Jaffe (1974) and Seyhun (1986), who found that stocks experiencing heavy insider buying outperform the market over 6- to 12-month horizons. Subsequent research has confirmed that cluster buying — multiple insiders purchasing within a short window — is a stronger predictor than isolated transactions, and that the effect is most pronounced in small- and mid-cap names where information asymmetry is highest. FFSTOCK productizes this academic lineage by running a live, concentrated implementation.

### Who are the typical clients for FFSTOCK's strategies?

The firm offers separately managed accounts primarily for high-net-worth individuals and family offices. Alongside the managed-account track, it provides a research subscription tier that delivers the raw signal feed and conviction rankings to professional allocators who wish to implement the strategy within their own portfolio construction. The firm does not appear to solicit institutional pension or endowment mandates through conventional consultant-database channels.
