{ "model": "minimax/minimax-m2.7", "started_at": "2026-06-11T01:27:45.633Z", "system_prompt": "You are Scout, the deep-research stage of an AI trade-ideas pipeline.\n\nThe pipeline operates against the Catalyst-Edge methodology documented in\nMETHODOLOGY.md. Your job is to investigate ONE symbol thoroughly and produce\na research dossier in strict JSON. You do NOT form a thesis or recommend a\ntrade — the Analyst will compute a 0-100 composite score over your raw inputs\nand decide whether to draft.\n\nYou are explicitly allowed — and encouraged — to conclude \"no anomaly worth\npursuing\" when the facts don't support an interesting setup. The pipeline's\ndefault outcome is silence; mediocre dossiers are worse than no dossier.\n\nVERDICT VOCABULARY — pick exactly one:\n\n promising\n A long-side asymmetric setup. Mispricing + catalyst + edge in data.\n Analyst will consider long_stock / CSP / asymmetric long.\n\n range_bound_or_income\n Stock is fundamentally healthy but FULLY VALUED — at/near 52w high,\n rich on forward P/E vs sector, IV elevated, no clear near-term\n catalyst for further upside. This is NOT a no-action verdict. It's\n a STRUCTURED-INCOME verdict. Use it whenever the dossier supports a\n covered-call / strangle / out-of-the-money put-write thesis even if\n no asymmetric long exists. Analyst will consider cc / strangle /\n csp on pullback.\n\n bearish_setup\n Deteriorating fundamentals + bearish catalyst + IV elevated. Open to\n naked_call (carefully — uncapped risk) or short-stock theses.\n Analyst may issue a downside thesis.\n\n no_anomaly\n Genuinely nothing here — either inconclusive data, fully-priced WITH\n low IV (so no income premium), or no thesis of any direction works.\n Pipeline halts.\n\n needs_more_data\n Data sources weren't sufficient (filing gaps, illiquid options, news\n blackout). Re-investigate later.\n\nCRITICAL: Do NOT use 'no_anomaly' as a default for fully-valued mega-cap\nnames. Those are precisely the candidates for income strategies. Reach\nfor 'range_bound_or_income' first; reserve 'no_anomaly' for cases where\nno structure across the full menu is attractive.\n\nTHE FRAMEWORK YOU ARE GATHERING DATA FOR\n\nA publishable idea satisfies all three:\n 1. Mispricing — market value diverges from defensible intrinsic value\n 2. Catalyst — specific event in 3-12 month window forcing re-rating\n 3. Edge in data — something the market missed (read filings nobody read,\n cross-referenced data nobody cross-referenced)\n\nThe Analyst will score 0-100 weighted across 5 categories. Your dossier needs\nto include the RAW INPUTS for each category — the Analyst doesn't re-fetch\ndata. Categories:\n\n - Smart-money cluster (max 25 pts): insider open-market buys, 13F\n initiations from skilled managers, politician disclosures\n - Options flow / UOA (max 10 pts): whale OTM blocks, V/OI > 1, IV skew\n - Catalyst (max 25 pts): named event in window, recent surprises, guidance\n - Mispricing (max 15 pts): forward P/E vs sector, EV/EBITDA, FCF yield, SOTP\n - Quality (max 15 pts): ROIC, margin trend, balance sheet\n - Momentum/technical (max 10 pts): MAs, RSI, MACD\n\nINVESTIGATION CHECKLIST (cover everything below; stop early only if a fatal\nred flag is found, in which case set verdict='no_anomaly')\n\n Fundamentals & valuation (Mispricing + Quality):\n □ fundamentals(ticker) — market cap, growth, margins, balance sheet\n □ For a peer comp, fetch fundamentals on 1-2 named competitors, compute\n forward P/E and EV/EBITDA delta vs sector median\n\n Filings (Edge — read what others didn't):\n □ edgar_recent_filings(ticker, '10-K', 1) → edgar_filing_text on the URL.\n Read MD&A, segment disclosures, risk factors. Note specific numbers.\n □ edgar_recent_filings(ticker, '10-Q', 4) → read most recent for trend\n □ edgar_recent_filings(ticker, '8-K', 10) → look for material events\n\n Smart money:\n □ edgar_form4_insiders(ticker, 25) — note count of distinct insiders,\n cluster timing, transaction codes (P=purchase is the signal; A,G,F are\n noise). Flag any CEO/CFO buys explicitly.\n □ Note: 13F deltas and politician trades are deferred tools (v2). For now\n note in 'unfetched_signals' if you'd want them.\n\n Catalyst:\n □ earnings(ticker) — next reporting date, recent surprise pattern,\n forward estimates\n □ news_for_symbol(ticker, '90d', 30) — scan for catalysts: M&A, regulatory,\n contracts, guidance changes, sector inflection. Distinguish real\n catalysts from noise (clickbait headlines like \"3 Stocks for the Next\n Decade\" are noise).\n □ news_for_sector('semis', '30d') if sector inflection is the angle\n\n Technical confirmation (low weight per methodology):\n □ technicals(ticker) — RSI/MACD/MA stack\n □ price_history(ticker, 365) only if you need historical context\n\n Options flow / UOA (Tier 2 — corroborator):\n □ options_flow(ticker) — aggregate put/call ratio, net dollar bias, whale\n blocks, strikes with V/OI > 1 (new positioning, not just turnover).\n Note whale_call_blocks_otm and flow_directional_bias for the score.\n\n Options environment (only if structure selection might be CSP/CC):\n □ options_expiries(ticker)\n □ options_chain on a relevant expiry, strikes_around 15\n\nUSE YOUR BUDGET. Aim for 20+ tool calls per investigation. A dossier built on\n6 quick calls is junk. Read the full 10-K. Read the latest 10-Q. Cross-check\nfilings against news.\n\nINVESTIGATION DEPTH\n Aim for depth, not breadth. A dossier built on 20+ tool calls reading actual\n filings is far more valuable than a dossier built on 5 tool calls reading\n summaries. You have up to 50 tool calls and 6 hours wall time. Use them.\n\n Suggested investigation order (adapt as the data warrants):\n 1. fundamentals(ticker) — the basic shape\n 2. price_history(ticker, 252) — 1-year context\n 3. edgar_recent_filings(ticker, 10-K, 1) — most recent annual\n 4. edgar_filing_text(<10-K url>) — actually read it\n 5. edgar_recent_filings(ticker, 10-Q, 4) — last 4 quarters\n 6. edgar_filing_text on the latest 10-Q — read it\n 7. edgar_recent_filings(ticker, 8-K, 10) — recent material events\n 8. edgar_form4_insiders(ticker) — insider activity pattern\n 9. earnings(ticker) — upcoming, history, surprise %\n 10. news_for_symbol(ticker, 90d) — 3-month news + catalysts\n 11. options_expiries(ticker) — what's available\n 12. options_chain on a relevant expiry, strikes_around 15\n 13. (if catalyst-driven) news_for_sector('semis', 30d)\n\n Read enough filing text to actually understand the business.

Let me analyze what I've found:\n\n**INSIDER ACTIVITY:**\n1. The June 10, 2026 filings were all RSUs vesting at $0 — these are compensation grants to directors (Paul Caine, Diane Yu, Robert Spillane, Sarah Harden), NOT open-market purchases. Code \"A\" = acquired as RSU compensation.\n2. David Buonasera (CTO) had a SALE on June 1, 2026: sold 1,409 shares at $15 via 10b5-1 plan.\n3. Robert Spillane (Director) SOLD 10,000 shares on May 19, 2026 at ~$13.33.\n\n\n4. The CEO and President all had vesting-forfeiture transactions around the same time, while CFO David Day didn't appear in recent filings.\n\nSo the insider cluster isn't actually a bullish signal — it's mostly RSU compensation grants with some selling activity mixed in.\n\nThe analyst ratings are genuinely bullish with $20+ price targets versus the current ~$15.67, and Q1 2026 showed strong momentum swinging to profitability compared to losses last year. CTV growth is accelerating at 30% annually, which explains the positive sentiment from RBC and BTIG. The stock has bounced sharply off its February lows but remains well below the $26.65 highs, suggesting there's still room for upside if the fundamentals continue improving.\n\nThe valuation looks reasonable with a forward P/E around 12-13x, though leverage is elevated at nearly 47% debt-to-equity and net debt of roughly $245M against EBITDA of ~$145M annually gives an 18x leverage multiple. The recent draw on the revolver to handle convertible note maturities in Q1 is worth monitoring from a balance sheet perspective.\n\nLooking at the options activity, there's been heavy bullish call positioning with over 1,000 contracts trading at-the-money strikes around $16, which suggests significant speculative interest pushing the stock higher despite elevated implied volatility ranging from 50-77%. The technical setup shows RSI approaching overbought territory and recent MACD momentum turning positive as the stock reclaimed its 50-day moving average.\n\n\n\n", "cleaned_content": "", "tool_calls": [ { "type": "function", "id": "992434528", "function": { "name": "fundamentals", "arguments": "{\"ticker\":\"TTD\"}" } }, { "type": "function", "id": "595953739", "function": { "name": "news_for_symbol", "arguments": "{\"ticker\":\"MGNI\",\"since\":\"30d\",\"limit\":10}" } } ], "finish_reason": "tool_calls" }, { "ts": "2026-06-11T02:03:04.575Z", "raw_content": "Now I have enough data to compile a comprehensive dossier. Let me analyze:\n\n**Key findings:**\n\n1. **Form 4 Cluster — NO open-market purchases (P-code)**: The recent Form 4 filings in last 14 days were predominantly RSU vestings/grants with code \"A\" (acquisition/grant at $0) and one S-sale by director Robert Spillane. No genuine P-codes (open market purchases). This was a false positive trigger — the investigation trigger flagged RSU compensation grants, not insider buying.\n\n2. **Smart money**: Only one open-market transaction: Robert F. Spillane sold 10,000 shares at ~$13.33 on May 19 (code S), which is selling. CEO Barrett had an ESPP purchase of $1,316 worth but that's negligible and via code F (forfeiture/ESPP). David Buonasera (CTO) also only had a sale pursuant to Rule 10b5-1 plan.\n\n\n3. **Price context**: Stock at $15.67 with -22% YTD decline, though recovering from the February low of $11.20. Analyst sentiment is bullish with BTIG and RBC both targeting $20, but the stock trades at just 12.68x forward earnings despite returning to profitability in Q1 2026 after being loss-making a year earlier.\n\n4. **Business fundamentals**: Revenue is modest at $722M TTM with slow 5% growth, though gross margins are solid at 63%. The balance sheet shows concerning leverage with net debt of ~$245M against EBITDA of roughly $145M (net debt/EBITDA around 1.7x), and the recent convertible senior note repayment required a $60M draw on the credit facility in May.\n\n5. **Recent momentum**: BTIG's bullish initiation coverage drove a jump, supported by strong Q1 CTV contribution growth (~30% YoY), expanded partnerships with JioHotstar and Walmart Connect via Vizio inventory, plus new dentsu activation deals across Sweden—suggesting multiple growth vectors emerging simultaneously.\n\n6. **Positioning and valuation**: Call skew is heavily bullish with a $16 strike whale block showing elevated implied volatility (50%), indicating institutional conviction on the upside despite recent weakness.\n\n7. **The critical issue**: The 8 Form-4 filings in 14 days aren't what they initially appear—these are RSU vesting transactions with code \"A\" rather than actual open-market purchases, which fundamentally changes how I should weight this signal.\n\n\n{\"symbol\":\"MGNI\",\"company\":\"Magnite, Inc.\",\"investigation_summary\":\"Despite the investigation trigger flagging 8 Form-4 filings in 14 days, a thorough reading of each filing reveals NO open-market insider PURCHASES (P-code). The cluster consists almost entirely of RSU grants/vestings at $0 value and one director S-sale — a false positive. MGNI returned to profitability in Q1 2026 (+$4.4M net income vs -$9.6M loss YoY) with strong analyst coverage initiation from BTIG ($20 target, Buy) and RBC (Outperform). CTV contribution grew ~30% YoY, partnerships are expanding (JioHotstar, Walmart Connect via Vizio, Dentsu Sweden), yet the stock trades at only 12.7x forward P/E vs a sector peer set commanding 25-35x. The stock has recovered from $11 February lows but remains -22% YTD. Options flow is notably bullish (88% call-dominant net bias, whale OTM call block at $16 strike).
