Confidence: 30% Alpha Score: 0.28

A blended fair-value estimate combining up to six valuation methods. Each method is weighted by how well it fits the company — DCF down-weights for unprofitable names; DDM only fires for steady dividend payers; comparables down-weight when peer multiples disagree.

  • DCF (quality-aware) — projects free cash flow with a horizon that scales to business quality. True compounders (quality 6/6) get 10 years explicit + 10 years fade before terminal; cyclical/struggling names (quality 0-1) get a 5-year terminal cliff. Quality is scored from ROE, gross margin, growth, FCF margin, debt load, and FCF consistency — the same factors that drive market premium for compounders.
  • Market-Implied Growth (in Model Inputs) — reverse-DCF that answers "what growth rate is the market pricing in?". Lets you sanity-check the deviation: if implied growth is plausible for the business, the model's bearish flag may be wrong; if implausible, the market may be over-extrapolating.
  • DDM (Gordon Growth Dividend Model) — values the stream of future dividends. Only used when trailing yield ≥ 0.5% and dividend payments are stable.
  • P/E, EV/EBITDA, P/B, P/S — applies the peer-group median multiple to this company's per-share metric. Peers come from the same set as the "Related symbols" card. Earnings/sales metrics are forward-tilted by the company's recent revenue growth (capped at 25%) so they're comparable to peers' growth-embedded multiples — mimics how analysts use NTM rather than TTM. Per-multiple weights are biased by company quality (e.g. P/B down-weighted for asset-light tech).
  • Market Anchor (SMA50) — the 50-day moving average, weighted by recent trading-range stability (tighter Bollinger bands → higher weight). Captures information fundamentals miss (forward consensus, sentiment, supply/demand) — but only when recent trading is steady enough that the market has converged on a view. During wild breakouts or breakdowns the anchor's weight collapses.
  • Options Expected (B-L 30d) — the risk-neutral expected stock price at 30-day options expiration, derived from the full implied-volatility surface via Breeden-Litzenberger (second derivative of call price wrt strike → implied PDF, then E[S_T]). Forward-looking, captures all options-implied information (smile, skew, term structure) in one number. Weighted by chain liquidity. SP500-only at present (pre-computed daily). Backtest evidence: adds modest alpha across most bucket × holding combos.
  • Blended value — weighted average. Confidence reflects how many methods fired and how tight peer dispersion is.
  • Deviation pill — green when blended FV ≥ 10% above current price (undervalued); red when ≥ 10% below; grey otherwise.

Expected α = forward-return point estimate vs SPY (e.g., +7.5% means the predictor expects this stock to outperform SPY by 7.5% over that horizon). For SHORT direction the model uses a different ranking metric (conviction-weighted deviation, not the LGBM prediction); Expected α is shown for reference. ⚠ flags rows where Expected α disagrees with the FV direction — two independent signals are in conflict; conviction is low even if rank looks extreme.
Forward-Return Rank. A proprietary ensemble of a machine-learning forward-return model and a conviction-weighted fundamental score, ranked cross-sectionally each day across the S&P 500 (and broader universes on the screener). Each stock is scored at three horizons (21/42/63 trading days). "Active" = top/bottom 5% AND all risk filters pass. Backtested mean alpha vs SPY on active picks: 21d LONG +13.4%, 63d +34.9% (S&P 500, walk-forward). Past performance is not indicative of future results.
Value vs momentum conflict ⚠. The "FV direction" (long/short) comes from the fundamentals-based engine — price vs intrinsic value. The "Expected α" comes from a separate machine-learning predictor trained on ~12 features (sector, options-implied move, beta, institutional flow, etc.). Sometimes the two disagree: a stock is overvalued by fundamentals but the predictor expects it to keep outperforming (sector or momentum tailwinds). When all 3 horizons disagree, treat the direction signal as low-conviction — neither model is strongly recommending a position.

Technical Indicators

Quick-reference for reading the values below. Indicators combine to confirm a view — no single one is a trade signal on its own.

Trend Indicators
  • 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.
Momentum Oscillators
  • 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.

Volume & Volatility
  • 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 →

Spread Scanner GPU
Full Algorithm Docs ↗

Each spread is ranked by a composite score built in three stages. Full documentation →

Stage 1 — Base Score (GPU scanner)

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.

Stage 2 — Skew Adjustment (±25% cap)

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.

Stage 3 — Technical Overlay (±50% cap, 5 groups)
Group 1 · Directional Bias (±0.25)
  • RSI <40 bullish / >60 bearish
  • MACD crossover + histogram trend
  • Price vs SMA 50 & SMA 200
Group 2 · Momentum (±0.10)
  • Stochastic %K <20 / >80
  • Williams %R <−80 / >−20
Group 3 · Volatility (up to −0.25 / +0.15)
  • Blended ATR + straddle expected-move penalty
  • Bollinger Band signal (+ counter-trend penalty)
  • BB width — vol contraction boost for ICs
Group 4 · IV Regime (±0.15)
  • IV rank ≥ 75 → strong boost for credit spreads
  • IV rank < 25 → penalty (selling cheap vol)
Group 5 · Liquidity (penalty up to −0.10)
  • 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 →

Skew (Wing IV − ATM IV)
DTE:
Wing Δ:
Metric:
Wing vs ATM
IV(put wing) − IV(ATM), in vol points

How 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.
Risk Reversal
IV(call wing) − IV(put wing), equal delta on each side

Which 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.
Reading them together

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.

What 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. Amendments (Form 144/A) and post-cancellation refilings can inflate this if you sum naively; the rollup above excludes filings with zero stated value.

Fundamentals

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.

Metrics
  • 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.
How to read the bars
  • 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.
