How Sideravia works
No black boxes: every number on the dashboard is reproducible from the rules below, and our own recommendations are measured publicly against the market.
1 · The Sideravia Score™ (0–100)
Every stock is ranked against its whole universe (e.g. the S&P 500) as a percentile blend of six pillars: Quality 25% (ROE/ROIC, margins, Piotroski F-Score), Strength 20% (Altman Z, leverage, coverage), Valuation 20% (P/E, EV/EBITDA, FCF yield — inverted, cheaper = higher), Growth 15%, Momentum 15% and Income 5%. A 75 means "better than ~75% of the universe on the weighted blend" — it is a relative rank, not a price target.
2 · The verdict (Attractive · Neutral · 🔴 Caution)
A deterministic weight-of-evidence read across independent signals (valuation gap, quality, trend, insider activity, analyst view). It is rule-based — the same inputs always produce the same verdict — and every supporting/opposing signal is shown next to it.
3 · Opportunities & conviction
Eight independent signal families (value gap, quality, trend, momentum breakouts, post-earnings drift, insider buying, seasonal patterns, low crowding) are checked daily. Conviction (0–100) rises with confluence — how many unrelated families agree — and the weights are tuned by our own measured signal accuracy (rank IC), not opinion.
4 · The evidence loop — we grade ourselves
Every night the ranked opportunities and scores are frozen (point-in-time, before the returns they'll be judged against — no look-ahead). The Evidence page then reports, on live data: signal rank-IC per metric, forward returns by tier vs SPY, the weekly-recommendation track record (win rate, profit factor, alpha), and the published-picks record. When a sample is too small to trust, we say so instead of showing it.
5 · The AI layer is grounded
Every AI feature (decision brief, red-team, chat, filing digests) reasons only from the stock's own data shown on the page — scores, financials, SEC filings — and must cite the figure it uses. It never invents numbers; when the data can't answer, it says so.
6 · Data sources & limits
Prices, fundamentals, analyst views, and filings are sourced from licensed market-data providers and public regulatory filings. Data is refreshed nightly (some fields weekly) and each card shows its freshness. Sideravia is research, not financial advice — the verdicts are inputs to your decision, and the track record page exists so you can judge how much weight they deserve.
7 · Pre-registered retirement criteria
A track record only means something if the rules for failure are written down before the results are in. So we pre-register them: a published pick strategy is retired if, once it has at least 20 measured cohorts at its primary horizon (Long-Term: 90 days · Medium-Term & Quant: 60 days · Short-Term: 30 days), its average excess return vs the equal-weight S&P 500 (RSP) is zero or negative over the trailing 26 weeks. A retired strategy stops being published, and its full record stays on this site — archived, never deleted. Construction changes (like the sector cap added 14 Jul 2026) are disclosed the day they ship and never applied retroactively.
