Limitations & Risk Disclosure
Last updated: May 11, 2026
This page outlines the limitations of US Stock Sigma's data and the material risks of trading on the information it provides. All content on the Site is educational and informational in nature — not investment advice, and not a trading signal. Read this page carefully before relying on any published value to make a trading decision.
1. Not Investment Advice
We do not know your financial situation, risk tolerance, investment objectives, position book, tax situation, or regulatory environment. The values and commentary we publish therefore cannot constitute personalized advice and should not be construed as a recommendation to buy or sell any specific instrument. Final judgment and responsibility rest entirely with you.
2. General Limitations of Probabilistic Indicators
Expected Move, ±1σ ranges, and similar probabilistic outputs are not deterministic predictions of future price. Key risk factors include:
- Tail risk — Rare but large price moves occur more frequently than a normal distribution suggests.
- Asymmetric distributions & regime shifts — Volatility clusters; quiet markets can flip into violent ones with little warning.
- Event-driven gaps — Earnings, geopolitical shocks, and macro surprises can cause overnight or intraday gaps that bypass our ranges entirely.
3. Leveraged & Inverse ETF Risks
Leveraged and inverse ETFs (e.g., 2x, 3x, −1x products) carry additional structural risks including:
- Daily reset / compounding decay
- Volatility drag over multi-day holding periods
- Gap risk on the underlying basket
- Tracking error vs. the stated multiple
Our published ranges reflect observed market data at a point in time and do not offset or compensate for the structural risks unique to leveraged products.
4. Practical Data & Calculation Limitations
- Low liquidity — Wide bid-ask spreads and sparse strikes reduce the reliability of derived IV and walls.
- Event-loaded expirations — Earnings or macro events embedded in an expiration cycle distort IV-derived ranges.
- Intraday volatility — Values published at close may diverge quickly once the next session opens.
- Ticker symbol events — Splits, mergers, and ticker changes can introduce stale or inconsistent data temporarily.
5. Recommended User Practices
- Never trade on a single indicator — combine our data with your own analysis.
- Define pre-trade risk limits (max loss, position size) before entering any trade.
- Check the economic and earnings calendar for events that affect your tickers.
- Verify liquidity (volume, open interest, bid-ask spread) before sizing positions.
- Cross-reference levels with order flow and structural context.
6. Loss Potential & Limitation of Liability
Trading involves the risk of loss, including loss of more than your initial investment for certain leveraged products and options strategies. US Stock Sigma assumes no legal responsibility for losses incurred through reliance on Site content. By using the Site, you acknowledge that you trade at your own risk.
7. Changes & Notifications
We may update this Risk Disclosure as our product, data sources, or market conditions evolve. Material changes will be announced on the Site or via email to subscribers.
8. Summary
Use our data as one input among many. Define your own risk rules. Never trade capital you cannot afford to lose. If in doubt, consult a licensed financial professional.
