INDICATOR COMPONENTS
The InsiderStreet Score combines six investment factors: Earnings Quality, Financial Quality, Relative Valuation, Risk/Safety, Price Momentum, and Insider/Smart-Money Trading. Scored 1–10, ranked vs sector peers. Weights: Quality 35%, Value 30%, Momentum 12%, with 22% weight on InsiderStreet's proprietary Insider/Smart-Money factor — the data layer that distinguishes us from generic equity research.
OPTIMIZED SCORE
The Optimized Score uses backtested factor weightings derived from historical return attribution. For large/mid cap stocks, Financial Quality and Earnings provide the most explanatory power. For small/micro cap, Insider Trading and Momentum dominate. Companies with Optimized Score ≥ 7 have historically outperformed over 12 months.

HIGHLIGHTS
METHODOLOGY
InsiderStreet Score (0-10). Composite of six factors: Earnings Quality (18%), Financial Quality (18%), Relative Valuation (15%), Risk/Safety (15%), Price Momentum (12%), Insider/Smart-Money (22%). Each factor is independently scored 0-10 from underlying data, then weighted into the composite. Stocks with composite ≥7 have historically outperformed the S&P 500 over rolling 12-month windows.
Edge Score. InsiderStreet's proprietary competitive-advantage score (0-100), built from five sub-pillars: Cost Advantage, Intangibles, Switching Costs, Network Effects, and Scale. Ratings: Wide (≥70), Narrow (40-69), Limited (<40).
Insider/Smart-Money Factor. The differentiator. Built from Form 4 (corporate insider) transactions, Form 144 (planned sales), 13F (institutional) Q-o-Q changes, ETF accumulation, Congressional (House + Senate) trades, dark pool weekly notional, and FINRA short volume. Each input is percentile-ranked vs sector; composite re-percentile-ranked vs market.
Data Freshness. 13F filings are due 45 days after quarter-end. If the latest quarter's filing window is open AND we have less than 90% of prior-quarter filer count, we suppress Q-o-Q comparisons and label the data as in-progress.
Fair Value. Three models: Conservative EPS (P/E reversion to historical norm), Base Growth (forward EPS × industry mean P/E), Optimistic Growth (analyst-implied price target). Final fair value range presented; current price compared to base.
