What We Detect

Insider Transactions

When a CEO, CFO, or director purchases shares in their own company, the Form 4 filing is captured within seconds. SignalHunter scores the amount, the cluster size, and whether multiple insiders are buying at once.

FDA and Regulatory Approvals

Drug approvals, clinical trial results, and PDUFA calendar dates are monitored continuously. A positive Phase 3 outcome can move a stock more than 50 percent in a single session.

Government Contracts

Defense contracts, federal grants, and procurement awards are captured from SEC filings and press releases the moment they are published. Contract values and counterparties are extracted automatically.

Earnings Catalysts

Earnings beats, guidance raised, margin expansion, and revenue acceleration are detected within seconds of 8-K and 10-Q publications. Raised guidance is one of the strongest positive signals in the scoring model.

Strategic Partnerships

Major customer wins, material agreements, and joint venture announcements that materially change the revenue trajectory of a company are flagged and scored based on deal significance.

Activist and Institutional Activity

When a known activist investor discloses a position via a 13-D or 13-G filing, or when unusual options activity precedes an announcement, SignalHunter captures it immediately.

Volume and Momentum Signals

Unusual trading volume and relative price strength patterns that historically precede significant price moves are detected and cross-referenced with catalyst data.

Corporate Actions

Share buyback programs, spinoff announcements, and merger and acquisition filings are processed with context on deal terms, premium paid, and strategic rationale.
