AI Risk Radar Signals From Market Breadth, Earnings Revisions, and Option Skew
If you trade or allocate in modern equity markets, you’ve likely felt the whiplash: the index looks fine, headlines look noisy, and risk “suddenly” spikes. The problem isn’t that markets are unpredictable—it’s that most people monitor risk with too few instruments. This research proposes seven practical risk radars built from AI risk radar signals from market breadth, earnings revisions, and option skew—three data families that often reveal regime shifts before your P&L does.
This is also where SimianX AI fits naturally: instead of drowning you in indicators, a multi-input workflow can summarize why conditions are changing and turn them into decision-ready alerts. (We’ll show a step-by-step implementation playbook you can run inside a dashboard-style workflow.)

Why “seven radars” beats “one magic indicator”
Single indicators fail for three predictable reasons:
- Regime dependence: what worked in disinflation may fail in inflation shocks or rate volatility.
- Timing mismatch: volatility often rises after damage begins.
- Distortion: flows, concentration, and options positioning can mask internal weakness.
A radar system is different: it cross-checks independent information sources so you don’t overtrust one lens.
A pilot doesn’t fly by one gauge. A trader shouldn’t manage risk with one chart.
The three data families (and what they really measure)
- Market breadth = participation and internal health (are many stocks carrying the move, or just a few?).
- Earnings revisions = forward fundamentals in motion (are expectations improving or decaying?).
- Option skew = tail-risk pricing and hedging pressure (are investors paying up for crash protection?).
The seven radars below are grouped as 3 breadth radars + 2 revisions radars + 2 skew radars.

The Seven Key Risk Radars (framework map)
Here’s the full system in one view.
| Radar # | Name | Data family | What it detects earliest | Best use |
|---|---|---|---|---|
| 1 | Participation Breadth | Breadth | Narrowing rallies, fragility | Reduce beta before cracks widen |
| 2 | Trend Breadth & Moving-Average Health | Breadth | Trend decay beneath index | Shift from “trend-follow” to “selective” |
| 3 | Leadership & Breakout Breadth | Breadth | Exhaustion, failed thrusts | Spot topping / late-cycle rotation |
| 4 | Net Revisions Diffusion | Revisions | Forward earnings momentum turns | De-risk cyclicals; avoid “multiple traps” |
| 5 | Revisions Dispersion & Guidance Stress | Revisions | Systemic vs idiosyncratic weakness | Decide if it’s “sector-specific” or “macro” |
| 6 | Skew Level & Tail-Hedge Demand | Skew | Crash insurance bid | Hedge earlier; size risk under tail pressure |
| 7 | Skew Term Structure & Gamma Shock Risk | Skew | “Pinball” markets, gap risk | Reduce leverage; plan event hedges |
The rest of this paper explains each radar with:
- What to measure
- How to score it
- How to interpret it
- Common traps
- Action playbook
- How to operationalize it in SimianX AI

Radar 1 — Participation Breadth (the “hidden concentration” alarm)
Core question: Is the rally carried by many stocks—or only a handful?
What to measure (minimal set)
Use 2–4 metrics that represent different angles:
- Advance/Decline (A/D) trend: are more stocks rising than falling?
- % of stocks above a key MA (e.g., 50-day): how broad is intermediate trend strength?
- Equal-weight vs cap-weight performance: is the average stock keeping up?
- Sector participation: are cyclicals confirming, or is leadership defensive?
Why it matters: A cap-weighted index can grind higher even while most stocks weaken. That divergence is a classic “risk is rising quietly” pattern.
Scoring (simple percentile approach)
Convert each metric into a percentile vs history (e.g., last 3–5 years):
- 0–20 = very weak participation
- 20–40 = weak
- 40–60 = neutral
- 60–80 = healthy
- 80–100 = very strong
Then average them into a Participation Score.
Interpretation rules (actionable heuristics)
- Index up + participation down = fragile regime → reduce beta, avoid crowded momentum.
- Participation up + index up = healthier trend → higher confidence in breakouts.
- Participation washed out = tactical opportunity only if revisions/skew confirm.
Breadth isn’t a “buy signal.” It’s a risk-condition signal.
Common traps
- Overreacting to one-day extremes (breadth is noisy).
- Confusing “narrow leadership” with “immediate crash” (narrowness can persist).
- Ignoring time horizon (daily breadth for day-traders; weekly breadth for investors).

Radar 2 — Trend Breadth & Moving-Average Health (the “trend decay” detector)
Core question: Are trends breaking under the surface?
If Radar 1 is about participation, Radar 2 is about trend integrity.
What to measure
- % above 200-day MA (long-term health)
- % above 50-day MA (intermediate health)
- Distance from MA (how stretched vs how broken)
- Optional: breadth momentum (rate of change of the above)
Why this radar is different
Participation can look “okay” while trends are deteriorating, especially during rotations. Moving-average breadth tells you whether the market is structurally healthy.
Practical signals
- Falling % above 200DMA while index holds = “ice thinning” regime.
- Sharp collapse in % above 50DMA = internal damage → expect volatility clusters.
- Rebound in MA breadth after capitulation = risk can become asymmetric (tactical long setups).
A minimal rule-set you can backtest
- If % above 200DMA < 40% → raise cash / hedge baseline.
- If % above 50DMA drops > 20 points in < 2 weeks → reduce leverage, tighten stops.
- If % above 50DMA rebounds > 15 points AND revisions stabilize → consider tactical risk-on.

Radar 3 — Leadership & Breakout Breadth (the “exhaustion / failed thrust” radar)
Core question: Is leadership expanding—or are breakouts failing?
This radar focuses on new highs/new lows dynamics and “breadth thrust” behavior.
What to measure
- New highs minus new lows (NH–NL)
- Breakout success rate (how many stocks hold above breakout levels)
- Sector leadership rotation (cyclical vs defensive balance)
- Volatility of leadership (how quickly leaders change)
The signal you’re looking for
- Index makes new highs but NH–NL weakens = topping risk rises.
- More defensive sectors lead while index remains strong = risk regime is changing.
- Breakouts fail rapidly = trend-following loses edge; mean reversion dominates.
How to act
- In leadership contraction: shift from “beta” to “quality + idiosyncratic edges.”
- Reduce position sizing on breakouts; demand tighter invalidation levels.
- If skew is rising simultaneously, treat failed thrusts as tail-risk warning, not “normal chop.”
When leadership gets narrower, markets become more sensitive to shocks.

Radar 4 — Net Revisions Diffusion (the “forward earnings momentum” radar)
Core question: Are analysts raising or cutting forward earnings expectations—broadly?
Prices can detach from fundamentals temporarily, but medium-term regimes often track earnings expectations. Revision diffusion (up vs down revisions) gives you a faster read than trailing EPS.
What to measure
- Net revision breadth = (% upgrades − % downgrades)
- Forward EPS momentum = 3–6 month change in next-12-month EPS
- Sector-level revisions = are cyclicals rolling over?
Why this radar matters for risk
Many drawdowns don’t start when earnings are “bad.” They start when earnings expectations stop improving. When revisions roll over broadly, multiples can compress even if the economy looks “fine.”
Scoring method (robust and simple)
- Convert net revision breadth to a z-score vs 3–5 years.
- Map to 0–100:
- z < −1.0 → 80–100 risk (revisions deteriorating)
- −1.0 to 0 → 60–80
- 0 to +1.0 → 30–60
- > +1.0 → 0–30 risk (revisions improving)
Practical interpretation
- Breadth weakens first, revisions follow: risk regime becomes persistent once revisions confirm.
- Revisions improving while breadth weak: could be rotation; avoid over-hedging.
- Revisions down + skew up: highest conviction “risk-off” cluster.

Radar 5 — Revisions Dispersion & Guidance Stress (the “systemic vs idiosyncratic” separator)
Core question: Are revisions concentrated in a few sectors—or spreading across the market?
Two markets can have the same index-level EPS forecast but completely different risk profiles.
What to measure
- Dispersion of revisions across sectors/industries
- Guidance balance (positive vs negative guidance counts)
- Margin stress proxies (downward revisions concentrated in margin-sensitive groups)
Why dispersion is a risk signal
- Concentrated cuts = sector problem (may create opportunities elsewhere).
- Broad, synchronized cuts = macro / policy / demand shock → higher systemic risk.
A simple decision tree
- If revisions deteriorate in cyclicals + spreads widen + skew rises → systemic risk.
- If revisions deteriorate in one sector only and breadth holds → rotation risk, not crash risk.
- If guidance turns negative broadly → de-risk growth exposure; reduce duration.
Common traps
- Taking index-level EPS at face value (concentration can hide weakness).
- Ignoring second-order effects (one sector’s cuts can hit suppliers/customers next).

Radar 6 — Skew Level & Tail-Hedge Demand (the “crash insurance bid” radar)
Core question: Is the market paying up for downside protection?
Option skew captures the relative pricing of downside vs upside optionality—especially out-of-the-money (OTM) puts. When skew steepens, the market is often signaling increased concern about tail outcomes.
What to measure (practical set)
- Index put skew (e.g., 25-delta risk reversal or put-call IV spread)
- SKEW-style tail-risk gauge (where available)
- Put/call ratio (context only) (avoid overtrusting it)
Interpretation
- Skew rising while VIX is low can mean: “calm surface, tail fear underneath.”
- Skew flattening during selloff can happen because ATM vol explodes faster than OTM (important nuance).
- Skew spike + breadth deterioration is higher signal than skew alone.
How to act (risk, hedging, positioning)
- Reduce leverage and tighten downside risk if skew steepens persistently.
- Consider structured hedges (collars, put spreads) rather than panic buying deep OTM.
- Use skew to decide when hedges become necessary—not to “predict the top.”
Skew is not a prophecy. It’s a price of insurance.

Radar 7 — Skew Term Structure & Gamma Shock Risk (the “pinball market” radar)
Core question: Are options dynamics likely to amplify moves?
Even if you don’t trade options, dealer positioning and term structure can influence realized volatility and intraday behavior. This radar focuses on how the market might move, not only where.
What to measure
- Skew by maturity (near-term vs 1–3 month)
- Event-driven skew (earnings, CPI, Fed)
- “Gamma sensitivity” proxies (fast moves, reversals, intraday mean reversion)
What the signal means in practice
- Front-end skew steepening = near-term tail anxiety → watch for gap risk.
- Term structure inversion in fear = traders paying up for immediate protection.
- Choppy, high-reversal tape can reflect hedging flows; trend signals degrade.
Action playbook
- Use smaller size, wider time stops (or shorter holding periods).
- Prefer defined-risk trades if volatility-of-vol rises.
- For investors: re-balance hedges before events when skew signals rising tail price.

How do AI risk radar signals reduce drawdowns (without killing returns)?
The goal isn’t to be “bearish” more often. The goal is to avoid being overconfident in fragile regimes.
A practical radar system reduces drawdowns through three mechanisms:
- Earlier de-risking: breadth deterioration flags fragility before headlines.
- Avoiding value traps: revisions rollovers warn when “cheap” can get cheaper.
- Smarter hedging: skew tells you when tail insurance is getting repriced.
A good system should be judged by:
- fewer deep drawdowns,
- smaller volatility clusters,
- better behavior (less emotional trading),
- and clearer sizing rules.

Building the composite score (a repeatable “risk weather” index)
To operationalize seven radars, you need a single composite plus explanations.
Step-by-step (7 steps)
- Pick universe:
SPX,NDX, or your portfolio’s stock set. - Select metrics per radar (keep it tight—avoid indicator bloat).
- Normalize each metric (percentiles or z-scores).
- Smooth noise (rolling 10–20 trading days, or weekly for investors).
- Build Radar Scores (0–100 risk).
- Weight into a Composite Risk Score.
- Map to regimes + actions.
Default weights (simple, defensible)
- Breadth radars (1–3): 45%
- Revisions radars (4–5): 30%
- Skew radars (6–7): 25%
Adjust by regime:
- Macro/rates shock → increase skew weight.
- Earnings season → increase revisions weight.
- Low-vol grind → participation breadth becomes more important.
Regime map (example)
- 0–30: Green (risk supportive)
- 30–55: Yellow (mixed; reduce overconfidence)
- 55–75: Orange (risk rising; hedge/trim)
- 75–100: Red (risk-off; preserve capital)

Practical “what-to-do” playbook (when the radar changes)
A radar only matters if it changes your behavior before the drawdown.
When Green → Yellow
- Reduce leverage and thin-margin trades.
- Tighten stops; shorten holding periods.
- Prefer quality balance sheets and consistent revision support.
When Yellow → Orange
- Reduce net exposure (beta).
- Add hedges (index put spreads, collars).
- Avoid crowded momentum if participation is narrowing.
When Orange → Red
- Prioritize capital preservation.
- Raise cash or rotate defensive.
- Avoid illiquid names; reduce gap risk.
- Focus on process: predefined actions > emotional reactions.

How to operationalize the seven radars in SimianX AI (workflow blueprint)
You can implement this as a daily/weekly workflow inside SimianX AI, where the system aggregates inputs, scores them, and generates explainable summaries.
A practical dashboard layout
Panel A — Composite Risk Score
- Current regime (Green/Yellow/Orange/Red)
- 1-week and 1-month trend in risk
Panel B — Seven Radar Tiles
- Each radar has: score, trend arrow, top drivers
Panel C — Explanation Layer
- Natural-language summary: “What changed and why?”
- “If-then” actions matched to your strategy style
Panel D — Decision Log
- Track: regime changes → actions → outcomes

Implementation steps (copyable checklist)
- Define metrics for each radar (2–4 each).
- Set thresholds as ranges (avoid overfitting precise numbers).
- Create alerts:
- “Two radars deteriorating” = caution
- “Four+ radars deteriorating” = defensive
- “Skew rising + breadth falling” = hedge review
- Backtest behaviors:
- Not “perfect prediction,” but reduced drawdown + improved decision quality.
Why AI helps here (the non-hype version)
AI should not be a magic button. Its real advantage is:
- summarizing cross-market drivers,
- detecting multi-input change points,
- keeping your decision process consistent,
- and turning signals into readable “risk narratives.”
That’s the philosophy behind explainable, multi-input workflows and why SimianX can be a practical home for this system.

FAQ About AI risk radar signals from market breadth, earnings revisions, and option skew
What are AI risk radar signals in stock markets?
They are multi-input indicators that combine internal participation (breadth), forward fundamentals (earnings revisions), and tail-risk pricing (option skew) into a regime-style view of risk conditions.
How often should I update market breadth and option skew radars?
Traders often update daily with smoothing; investors often update weekly. The right cadence matches your decision frequency—too fast creates noise, too slow misses regime shifts.
What is the best way to combine earnings revisions with breadth?
Use breadth as an early internal warning and revisions as confirmation of fundamental momentum changes. If both deteriorate together, risk regimes tend to persist longer.
Does option skew predict crashes?
Not reliably as a timing tool. Skew is better interpreted as the price of tail insurance—a way to see when market participants are paying more for downside protection.
How do I build an AI market risk dashboard without overfitting?
Use broad ranges instead of precise thresholds, keep the indicator set small, and test whether the system improves decisions (drawdown control, hedging discipline), not whether it “calls tops.”

Conclusion
A resilient risk process doesn’t rely on one indicator. It cross-checks seven key radars built from three powerful data families: market breadth, earnings revisions, and option skew. Breadth reveals hidden fragility, revisions show whether forward fundamentals are improving or decaying, and skew tells you when tail-risk pricing is changing beneath the surface.
If you want to operationalize this into a daily, explainable workflow—scoring, regimes, alerts, and decision logs—explore SimianX AI and implement the seven-radar system as a repeatable “risk weather” dashboard you can trust under pressure.
