Insider Trading Signals — November 28, 2025 — Daily Snapshot

1. Executive Summary

Insider activity filed on November 28, 2025 shows a mixed but dollar-weighted bearish tape. There were more purchase tickets (10) than sales (7), yet insiders sold roughly $1.9M vs. ~$0.3M in open-market buys, leaving net flows around –$1.6M.

The largest tickets came from Monolithic Power Systems (MPWR) in semiconductors and regional banks like Pinnacle Financial Partners (PNFP) and Truist Financial (TFC), where senior insiders trimmed positions. On the bullish side, Nerdy (NRDY), Dorchester Minerals (DMLP), and a cluster of small-cap biotech names (GLSI, MAIA, COCP, ICCC) saw insiders adding exposure. (Yahoo Finance)

Overall, the tape suggests rotations under the surface: insiders are cautious in tech and regional banks, while still quietly accumulating in healthcare, energy royalties, and niche consumer/education names.

2. Activity Breakdown

By transaction code (cash value uses reported transaction values):

Net Signal:

• Ticket count: Slightly bullish (10 purchases vs 7 sales)
• Dollar flows: Moderately bearish (sales exceed purchases by ~$1.6M)

  • 240 @ ~$912.30 (~$219.0K)
• Value: ~$851.7K
• Holdings impact: Under 1% of her remaining stake

2. 🔴 Pinnacle Financial Partners (PNFP) — Regional Bank Chair Cashes Out Partially

• Insider: Robert A. McCabe Jr., Chairman & officer
• Transaction: Sale of 6,775 shares @ $93.00
• Value: $630,075
• Holdings impact: ~3.2% reduction of his position
• Signal: Moderate Bearish
• Context: PNFP is a regional bank that remains profitable with solid analyst attention; a mid-single-digit trim looks more like portfolio management or diversification than an outright vote of no confidence. (Yahoo Finance)

3. 🔴 Truist Financial (TFC) — Director Sheds a Third of Stake

• Insider: K. David Boyer Jr., Director
• Transaction: Sale of 5,160 shares @ ~$46.45
• Value: $239,682
• Holdings impact: ~34% of his post-trade holdings
• Signal: Moderate–Strong Bearish at the individual-insider level
• Context: Truist is a large regional / super-regional financial services group that has faced profitability and growth concerns; a one-third trim from a director stands out on a day when financials otherwise see more selling than buying. (Morningstar)

4. 🔴 Olin Corporation (OLN) — VP & Treasurer Exercises, Then Sells

• Insider: Teresa M. Vermillion, VP & Treasurer
• Transactions (same date):
  • M: Option exercise of 4,500 shares @ $13.14 (paper value ~$59.1K)
  • S: Sale of 4,500 shares @ ~$20.86 (cash $93.9K)
• Holdings impact: Roughly 20.7% reduction of her stake
• Signal: Moderate Bearish / Partially liquidity-driven
• Context: OLN is a chemicals / basic materials producer; insiders often pair exercises with partial sales to lock in gains or manage risk, but a >20% stake reduction is still noteworthy. (Yahoo Finance)

5. 🟢 Nerdy Inc. (NRDY) — CEO & 10% Owner Adds Meaningfully

• Insider: Charles K. Cohn, CEO, director & 10% owner
• Transaction: Purchase of 119,242 shares @ $1.16
• Value: $138,320.72
• Holdings impact: ~8.5% increase in his stake (to ~1.40M shares)
• Signal: Strong Bullish
• Context: Nerdy operates an online learning platform using AI to match students and tutors; after a long period of stock underperformance and cautious analyst views, an 8%+ personal stake increase from the CEO is a clear vote of confidence at depressed prices. (Yahoo Finance)

6. 🟢 Dorchester Minerals (DMLP) — CFO & Director Buy Energy Royalties

• Insiders:
  • Leslie A. Moriyama, CFO — buys 3,041 shares @ $21.50 (~$65.4K)
  • Robert C. Vaughn, Director — buys 352 shares @ ~$21.39 (~$7.5K)
• Combined Value: ~$72.9K
• Holdings impact:
  • CFO: +3.6% stake
  • Director: +1.7% stake
• Signal: Moderate Bullish, small cluster
• Context: DMLP is an energy royalty partnership focused on oil & gas interests; recent earnings have been pressured by commodity swings, so coordinated insider buying hints at perceived value in the current distribution yield and asset base. (Morningstar)

7. 🟢 Greenwich LifeSciences (GLSI) — Founder-CEO Ticks Position Higher

• Insider: Snehal Patel, CEO, CFO, director & 10% owner
• Transaction: Purchase of 4,600 shares @ $8.37
• Value: $38,502
• Holdings impact: Only about 0.08% of his existing ~5.6M-share stake
• Signal: Weak–Moderate Bullish (symbolic sizing, but from top insider)
• Context: GLSI is a clinical-stage biotech working on immunotherapy to prevent breast cancer recurrence; a small add from the key founder-executive is mildly supportive but not thesis-changing given the huge existing position. (Yahoo Finance)

8. 🟢 MAIA Biotechnology (MAIA) — CEO & Director Buying Micro-Cap Biotech

• Insiders:
  • Vlad Vitoc, CEO, director & 10% owner — 10,500 shares @ ~$0.97 (~$10.1K)
  • Cristian Luput, Director — 10,000 shares @ ~$0.98 (~$9.8K)
• Combined Value: ~$20K
• Holdings impact:
  • CEO: +1.26%
  • Director: +2.5%
• Signal: Moderate Bullish, notable as two insiders step in
• Context: MAIA is a tiny oncology-focused biotech with a lead cancer therapy in development; in illiquid micro-caps, even five-figure insider buying can be meaningful, especially when both the CEO and a director participate. (Yahoo Finance)

9. 🟢 ICCC — Small Director Buy, Big % Increase

• Insider: David Scott Tomsche, Director
• Transaction: Purchase of 1,633 shares @ ~$4.77
• Value: $7,781.25
• Holdings impact: ~34.5% increase in his position
• Signal: Moderate Bullish despite small dollars
• Context: For a thinly traded healthcare micro-cap, percentage change in insider ownership often matters more than ticket size; this move significantly boosts the director’s alignment.

10. 🔴 Golden Matrix Group (GMGI) — CEO/10% Holder Takes Small Chips Off Table

• Insider: Anthony Brian Goodman, CEO, director & 10% owner
• Transaction: Sale of 50,000 shares @ $0.80
• Value: $40,000
• Holdings impact: Only about 0.67% of his ~7.4M-share stake
• Signal: Weak Bearish / Largely Neutral
• Context: This looks more like liquidity management than a strong negative signal given the very small fraction of his ownership being sold.

11. 🔴 Power Integrations (POWI) — VP Worldwide Sales Trims Holding

• Insider: Gagan Jain, VP, Worldwide Sales
• Transaction: Sale of 1,033 shares @ ~$33.80
• Value: $34,915.40
• Holdings impact: ~5.7% reduction
• Signal: Moderate Bearish
• Context: Together with MPWR, this contributes to a net-selling bias in semiconductors, despite strong AI-related demand stories in the group. (Yahoo Finance)

(Other entries — BLNE, COCP, GCTS, AKRO, LEDS, DOUG, MCI — are either small in dollar terms or neutral awards/reclassifications, but contribute to pattern and sector color below.)

4. Pattern Analysis

Cluster Buying in Small-Cap Healthcare & Biotech

• Names involved: AKRO (via option exercise), GLSI, MAIA (2 insiders), COCP, ICCC, GCTS
• Net Signal: Bullish — 6 purchases, no sales
• Dollar flows: Roughly $90K+ across the open-market buys (ex-awards)
• Context:
  • These are largely micro- to small-cap biotech / healthcare names where insider actions can be a meaningful informational edge. (Morningstar)
  • Sizing is modest, but the breadth of participation across tickers stands out.

Interpretation:
Insiders in speculative healthcare appear willing to add risk at current valuations, even while broader markets debate rate paths and funding conditions.

Energy Royalties Showing Quiet Confidence

• Ticker: DMLP (Dorchester Minerals)
• Activity: CFO + director open-market buying
• Net Signal: Moderate Bullish, concentrated in one name
• Context: DMLP’s business is tied to oil & gas royalty cash flows; insider buying after weaker earnings suggests insiders still see value in the underlying assets and distributions. (StockAnalysis)

Tech & Semiconductors: Profit-Taking at High Quality Names

• Names: MPWR, POWI (and stock awards at LEDS)
• Activity:
  • MPWR EVP & General Counsel: ~$852K of sales
  • POWI VP Sales: ~$35K of sales
• Net Signal: Moderate Bearish in dollars, small in percentage terms
• Context:
  • MPWR has rallied strongly on AI/edge-power themes but still trades below recent highs; sales by a senior legal executive might be scheduled or diversification-driven rather than a fundamental call. (MarketWatch)
  • Combined, these trades suggest some profit-taking in high-quality chip names after a strong run.

Financials: Regional Bank Insiders De-Risk

• Names: PNFP, TFC (MCI has neutral “J” adjustments)
• Activity:
  • PNFP Chairman sale (~$630K)
  • TFC Director sale (~$240K)
• Net Signal: Bearish for regional financials
• Context: Regional banks remain under scrutiny around funding costs, credit quality, and regulation; notable trims from senior figures reinforce a cautious stance in the group. (Yahoo Finance)

Mixed Signals in Consumer / Education

• Bullish: CEO/10% owner purchase at Nerdy (NRDY) (~$138K)
• Bearish: CEO/10% owner sale at GMGI (~$40K, tiny % of stake)
• Net Signal: Moderately Bullish, as NRDY dominates dollar flows
• Context:
  • Nerdy is trying to carve a niche in AI-enhanced online learning, with the stock pressured over the last year; CEO buying at these levels is notable. (Yahoo Finance)
  • GMGI’s small sale looks like routine liquidity.

6. Market Implications

1. Dollar flows lean cautious despite more buy tickets.
   While there are more purchase events, the cash is on the sell side, driven by six-figure trims in semiconductors and regional banks. That’s consistent with a market where leadership groups have run hard, and insiders are taking some chips off the table rather than making outright bearish bets.
2. Risk-on appetite persists in small-cap healthcare and energy royalties.
   The cluster of biotech and healthcare purchases, plus buying at Dorchester Minerals, suggests insiders in those niches still see attractive risk-reward despite volatility and funding concerns. These are often long-dated, idiosyncratic stories where management conviction can matter more than quarter-to-quarter macro headlines.
3. Single-name conviction stands out most at Nerdy.
   Among all trades, the NRDY CEO’s eight-plus-percent stake increase is the clearest high-conviction open-market buy. In a challenged, small-cap education name, that kind of personal capital deployment often signals management belief that the market is underpricing the long-term platform value.
4. Sales largely look like trims, not capitulation.
   Even in the biggest tickets (MPWR, PNFP, TFC), insiders are selling low-single-digit to mid-thirty-percent slices of their holdings, not exiting positions. That points more toward portfolio rebalancing, liquidity, or 10b5-1 plan execution than wholesale loss of confidence.

7. Key Takeaways

• Tech & semis: Insider sales at MPWR and POWI add to the narrative of profit-taking in AI-adjacent winners rather than aggressive top-ticking.
• Regional banks: Chair and director sales at PNFP and TFC keep the financials tape cautious, reinforcing that insiders are still wary about the rate and regulatory backdrop.
• Biotech cluster buying: Multiple small-cap healthcare names saw insiders adding, supporting a selective risk-on stance in higher-beta drug development stories.
• Energy royalties: Insider buying at DMLP suggests confidence that current oil & gas royalty cash flows and distributions are sustainable or undervalued.
• Standout conviction: The Nerdy (NRDY) CEO buy is the clearest single-name bullish tell in today’s filings.
• Size & context matter: Most sales represent partial trims, not exits; most buys are small but repeated, which often matters more over time than one-off big tickets.
