Each spoke is this symbol's rank within its sector (0–100; the dotted ring marks the sector median at 50). Higher is more constructive for a long. One spoke — News sentiment — is an absolute reading, not a sector rank. Grayed spokes have no data. A fuller shape is a summary, not a recommendation.

Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.
- SMA 20 / 50 / 200 — price above = uptrend, below = downtrend. SMA 50 crossing SMA 200 is the golden/death cross.
- EMA 12 / 26 — faster-reacting averages; 12 above 26 is short-term bullish.
- MACD — bullish when MACD > signal (green badge), bearish when below. Divergence from price often precedes reversals.
- ADX (14) — trend strength regardless of direction. <20 range, 20–25 weak trend, 25–50 trend, >50 strong trend.
- +DI / −DI — +DI > −DI favors bulls; the reverse favors bears. Read alongside ADX.
- RSI (14) — <30 oversold, >70 overbought. 40–60 is neutral; trending names can stay extreme.
- Stochastic %K / %D — <20 oversold, >80 overbought. %K crossing %D is an early momentum signal.
- Williams %R — inverted scale: <−80 oversold, >−20 overbought.
Oscillators work best in range-bound markets; in strong trends they give premature reversal signals.
- Bollinger Bands — price at upper band = overbought, lower = oversold. Narrow bands (squeeze) often precede expansion.
- OBV — cumulative volume; rising OBV confirms uptrend, falling OBV confirms downtrend. Divergence from price is a warning.
- Vol SMA 20 / Vol ROC — today's volume vs. 20-day average. Positive ROC with price move = conviction.
- ATR / True Range — average daily $ move; sizing and stop-loss reference.
- HV 20 / 30 / 60 — realized (historical) volatility. Compare to IV on the options cards: IV > HV = rich premium.
Confluence matters: trend + momentum + volume agreeing carries far more weight than any single indicator. For how these feed the spread scanner score, see the algorithm docs →

Volume & Volatility
Data Summary
LLM Stock Analysis Report
SYMBOL: NXL
Executive Summary
Overall Assessment: NEUTRAL (Confidence Level: 6/10)
Key Drivers: Positive news sentiment, high volatility, and weak trend signals.
Primary Risks: High beta, high volatility, and lack of earnings data.
Investment Thesis: NXL presents a mixed bag of technical and fundamental signals. The recent positive news headlines and high volatility create an interesting situation for potential investors. However, the stock's high beta and lack of earnings data pose significant risks that must be carefully considered.
Recent News Sentiment Impact: Positive news sentiment has dominated the past few months, with all six recent headlines having a positive tone. This sentiment aligns with the technical signals, which suggest a neutral market environment.
Technical Analysis
Trend Direction: Short-term: DOWN (SMA 20 below current price), Medium-term: NEUTRAL (SMA 50 and EMA 12 around current price), Long-term: UP (SMA 200 above SMA 50)
Support/Resistance Levels: Key resistance levels are the upper Bollinger Band ($0.63) and the previous highs near $0.50. Support levels are the lower Bollinger Band ($0.34) and the recent lows around $0.30.
Momentum Signals:
- RSI (14): 40.93 (neutral)
- MACD: Bullish crossover above signal line
- Bollinger Bands: Neutral, with price touching the middle band
Volume Analysis: Volume is trending down (-88.53% vs historical average), indicating a lack of buying pressure.
News & Sentiment Analysis
Recent Headlines Summary: All six recent headlines are positive, highlighting Nexalin's advancements in dynamic frequency stimulation for anxiety, depression, and insomnia, as well as the company's presence at industry events.
Sentiment Assessment: Positive sentiment dominates, with an overall sentiment score of 6/10 (very positive).
Catalyst Identification: Upcoming earnings release (if available) could be a catalyst, but without earnings data, it's difficult to assess potential impact.
Market Narrative: The recent news headlines and high volatility create a mixed market environment, where both bulls and bears have reasons to participate.
Risk & Volatility Assessment
Beta Interpretation: High beta of 2.31 indicates the stock is more volatile than the broader market (SPY).
Volatility Regime: High volatility regime (1.46) suggests significant price fluctuations are possible.
Options Market Signals: No options data available, but high IV premium vs HV30 suggests implied volatility may be richer than realized.
Downside Protection: Support levels at $0.34 and recent lows around $0.30 provide some downside protection, but the stock's high beta and lack of earnings data pose significant risks.
Market Context & Positioning
Sector Performance: NXL's sector performance is not available due to a lack of industry classification.
Institutional Activity: No institutional activity or volume patterns suggesting institutional interest are available due to limited data.
Correlation Analysis: Correlation with SPY is 0.20, indicating the stock has little correlation with the broader market.
Relative Valuation: NXL's relative valuation within its trading range is not clear without earnings data.
Key Levels & Action Items
Critical Price Levels: $0.63 (upper Bollinger Band), $0.50 (previous highs), and $0.30 (recent lows) are critical price levels to monitor.
Breakout/Breakdown Levels: A breakout above $0.63 or a breakdown below $0.30 could trigger significant moves.
Time-Sensitive Catalysts: Upcoming earnings release (if available) could be a catalyst, but without earnings data, it's difficult to assess potential impact.
Risk Management: Stop-loss levels should be set around the critical price levels mentioned above, and position sizing considerations should account for the stock's high beta.
NXL Options Activity & IV Rank
Each spread is ranked by a composite score built in three stages. Full documentation →
score = P(profit) × (credit / spread_width)
P(profit) from short leg delta (1 − |delta|), penalised above 85%. Credit uses mid-price to handle illiquid chains fairly.
RR and BF (30-delta) from the persisted per-symbol skew snapshot — wing strikes picked by real greeks.delta, not a moneyness proxy. Put skew boosts bull puts, penalises bear calls. High butterfly boosts iron condors. Calendars are skew-neutral.
- RSI <40 bullish / >60 bearish
- MACD crossover + histogram trend
- Price vs SMA 50 & SMA 200
- Stochastic %K <20 / >80
- Williams %R <−80 / >−20
- Blended ATR + straddle expected-move penalty
- Bollinger Band signal (+ counter-trend penalty)
- BB width — vol contraction boost for ICs
- IV rank ≥ 75 → strong boost for credit spreads
- IV rank < 25 → penalty (selling cheap vol)
- Min open interest across all legs
- OI < 100 → −0.10 · OI < 500 → −0.05
score = base_score × skew_multiplier × tech_multiplier
Both multipliers are shown per spread. Beta is informational only — ATR already captures realized vol. Full algorithm documentation →

IV(put wing) − IV(ATM), in vol pointsHow much the OTM put trades above (or below) the at-the-money strike. Measures the height of the put-side tail relative to ATM — i.e. how expensive crash insurance is on this name.
- Positive (typical) — wing IV > ATM IV. Standard equity put skew: portfolios bid up crash protection, so OTM puts trade richer than ATM.
- Near zero or negative (unusual) — wing IV ≤ ATM IV. Flat or inverted put side. Common when there's no fear demand, in tightly mean-reverting names, or right after an earnings catalyst clears.
- Percentile vs own 3-yr history: high = wings rich (good time to sell wing premium); low = wings cheap (good time to buy protection).
- Not directional — high or low wings don't predict up or down moves. It's a price tag on tail insurance, not a forecast.
IV(call wing) − IV(put wing), equal delta on each sideWhich side of the smile is the market paying up for? Measures the tilt of the surface — call skew vs put skew at matched deltas.
- Negative (typical) — puts richer than calls. Standard equity behavior: hedging demand makes puts carry a premium. Most large-caps sit in the −1 to −5 vol-point range.
- Strongly negative (< −5 pts) — heavy downside hedging, elevated fear, or an upcoming catalyst (earnings, FDA, macro event). Worth flagging.
- Positive — calls richer than puts. Unusual for equities; signals bullish momentum, short-squeeze positioning, or takeover/M&A speculation.
- Near zero — symmetric surface. Market sees roughly equal up/down risk. Rare for large-caps; more common in commodities and FX.
Wing-vs-ATM tells you how expensive the tails are. Risk Reversal tells you which side is favored. Combined:
- High wing percentile + deeply negative RR → strong put bid; stress or major event priced in. Owning protection costs a premium; selling put premium is dangerous.
- Low wing percentile + near-zero RR → complacency; insurance cheap and balanced. Good environment to add cheap downside hedges.
- Positive RR + elevated wings → call-side fear-of-missing-out; common in squeeze setups. Upside calls expensive, downside puts not bid.
Percentile is the rank of today's reading within ~3 years of this symbol's own history. High percentile = wings are rich relative to history; not a directional signal. Skew is read off the chain in real time, not from CBOE SKEW.

NXL Proposed Insider Sales (Form 144)
Latest: 2025-09-10What is Form 144? A notice of intent to sell restricted or control stock under Rule 144. Affiliates (officers, directors, 10%+ owners) and holders of restricted shares must file Form 144 when planning to sell more than 5,000 shares or $50,000 in any 3-month rolling window.
How it relates to Form 4: Form 144 is filed before the trade (up to 90 days in advance); Form 4 is filed within 2 business days after the trade executes. Not every Form 144 results in a sale — the filer may cancel or delay. Look for the corresponding Form 4 on the Insider Activity card to confirm a sale actually happened.
10b5-1 plans: Trades made under a pre-scheduled Rule 10b5-1 plan are not discretionary — they execute automatically on dates set months earlier, regardless of news. High 10b5-1 percentages mean less per-filing signal value, though cumulative selling volume still matters.
"Notice value": Aggregate market value the filer wrote into the Form 144 — i.e. the size of the planned sale, not necessarily the executed dollars. An amended notice (Form 144/A) replaces the original it amends, and cancelled notices are dropped, so neither is double-counted above. A filed value that is clearly inconsistent with the share count at the stock's price (a filer typo) shows as a dash and is left out of the totals.
Source & freshness: Sourced from public Form 144 filings. Refreshed daily; new filings typically appear here the morning after they are filed.

Quarterly filings sourced from SEC 10-Q / 10-K reports. TTM tiles aggregate the most recent four quarters; bars show the last ~12 quarters oldest → newest.
- Revenue — top-line sales. Look for consistent YoY growth; seasonal businesses need same-quarter comparisons (Q4 '24 vs Q4 '23).
- Net Income — bottom-line profit after all expenses. Can be volatile from one-time items; red bars = net loss.
- Diluted EPS — net income per share assuming options/converts are exercised. Direct input to the P/E ratio.
- Operating Cash Flow — cash generated from core operations, before capex and financing. Harder to manipulate than net income; growing OCF is a quality signal.
- Sequential growth — quarter-over-quarter trend. Accelerating bars are a momentum signal.
- YoY growth — compare to the same quarter a year earlier to remove seasonality.
- Quality — OCF should roughly track Net Income over time. Large divergence (net income ≫ OCF) flags accruals risk.
- Margins — scan the bar ratios: Net Income / Revenue tells you margin trend without needing a separate chart.
TTM (trailing-twelve-month) smooths seasonality and is used for the P/E calculation. Filings appear 30–90 days after the period closes.
