🤖 How the Engine Works
InsiderPopup Proprietary Intelligence Engine
InsiderPopup's intelligence engine processes raw SEC EDGAR Form 4 filings, congressional STOCK Act disclosures, and associated SEC filing activity against each ticker's 90-day baseline to identify statistically anomalous signals. A signal is flagged when the current week's activity diverges meaningfully from the established baseline across multiple data dimensions simultaneously. The engine assigns a composite score (0–100) reflecting the strength and breadth of the anomaly — not a price prediction or investment recommendation.

🥆 Top Bullish Anomaly — $SPGI
S&P Global is the world's leading provider of financial intelligence — credit ratings (S&P Ratings), market data (S&P Dow Jones Indices), commodity price benchmarks (Platts), and financial analytics (Market Intelligence). Three separate insiders buying a combined $1.04M in $SPGI this week, with zero offsetting sells, triggered the bullish anomaly flag. The analytical significance is in the baseline comparison: the engine's 90-day insider activity baseline for $SPGI was approximately $11,100 — meaning this week's $1.04M in insider buying represents a roughly 94x step-up from the established baseline. That magnitude of deviation from the norm, across three independent transactions simultaneously, is precisely the type of anomaly the engine is designed to surface. The accompanying 8-K material event filing adds a second signal dimension. In a week where the dominant narrative was insider selling into market highs, three $SPGI insiders chose to accumulate — a counter-trend conviction signal that sits in direct contrast to the broader de-risking tape.
90-Day Baseline: ~$11,100 avg insider activity · This Week: $1,038,813 across 3 transactions · Step-up: ~94x above baseline · No congressional activity detected
🥅 Top Bearish Anomaly — $LLY
10-Q + 8-K
SEC Filing Events
Eli Lilly is the world's most valuable pharmaceutical company by market capitalization, built on the extraordinary commercial success of its GLP-1 obesity and diabetes franchise (Mounjaro, Zepbound). The engine flagged $LLY as this week's highest-conviction bearish anomaly — composite score 77.25, the highest of any signal detected. Four independent bearish signals converged simultaneously: a $15.8M insider sell with zero offsetting buys; a congressional sell on top of the insider exit; a 10-Q quarterly filing delivering audited Q1 financials; and an accompanying 8-K material event disclosure. The 90-day insider baseline for $LLY was zero — meaning there has been no measurable insider sell activity in the prior three months, making this week's $15.8M exit a true first-occurrence anomaly rather than a continuation of existing patterns. The convergence of insider selling, congressional selling, and dual SEC filing events (10-Q + 8-K, the highest impact classification) in the same week produces the engine's strongest bearish signal of the May 4–8 period. This does not contradict $LLY's business fundamentals — GLP-1 commercial momentum remains intact. The anomaly flags an unusual concentration of insider and congressional reduction at a specific price and time point.
90-Day Insider Baseline: $0 (no prior activity) · This Week: $15,754,537 sell + $2,000 congressional sell · SEC Events: 10-Q + 8-K (highest impact classification) · News Sentiment: +0.10 (slightly positive, making the sell anomaly more pronounced)
These two signals represent statistically anomalous deviations from each ticker's established 90-day insider activity baseline, surfaced by InsiderPopup's proprietary intelligence engine. They are not buy or sell recommendations. The engine identifies where the data diverges from norms — context, due diligence, and independent analysis determine what to do with that information.
