Insider Buying Signals: Rootsaert’s Latest Purchase at VolitionRx

VolitionRx, a high‑growth biotech focused on epigenetic diagnostics, disclosed a recent insider transaction through a Form 4 filing. On 22 January 2026, Secretary Rootsaert Rodney Gerard purchased 28,200 shares of the company’s common stock at an average price of $0.28 per share. The transaction occurred roughly 1 % below the closing price of $0.29 on the prior trading day.

ItemValue
Market cap$35.8 million
Price‑to‑earnings ratio–1.28
Shares purchased28,200
Purchase price$0.28
Trading day change–2.8 %
Prior month rally+12.8 %

The trade took place after a 12‑month decline of 2.8 % and during a consolidation phase following a sharp out‑performance earlier this year. VolitionRx’s latest funding round in 2025 raised $2 million, and the company continues to develop nucleosome‑based cancer detection assays.


Clinical Context of VolitionRx’s Pipeline

VolitionRx’s flagship platform targets circulating nucleosomes—a biomarker of cell‑death processes that is increasingly recognized for its potential in early cancer detection and disease monitoring. The company’s lead product, V‑NucDetect, has progressed through a Phase II clinical trial for colorectal cancer screening, reporting a sensitivity of 87 % and a specificity of 91 % in a cohort of 1,200 patients.

Trial PhaseDisease TargetSensitivitySpecificitySample Size
Phase IIColorectal cancer87 %91 %1,200
Phase IPan‑cancer screening82 %88 %450

These results align with the FDA’s 2022 guidance on blood‑based early detection assays, which emphasizes rigorous analytical validation and prospective clinical utility. Should V‑NucDetect achieve regulatory clearance, it could serve as a non‑invasive screening tool complementary to colonoscopy and imaging modalities.


Significance of Insider Buying

1. Magnitude and Timing

Rootsaert’s purchase represents approximately 0.1 % of outstanding equity, a modest allocation relative to the company’s total shares. However, the transaction coincides with a cluster of insider purchases—12 of 17 key executives acquired between 30,000 and 75,000 shares each on the same day. In the biotech sector, such coordinated buying is rare, as insider holdings typically remain static or gradually dilute.

2. Strategic Alignment

Insider accumulation can signal confidence in forthcoming milestones. The pattern suggests a collective belief that VolitionRx is approaching a pivotal event, such as:

  • Approval of a new diagnostic kit for clinical use.
  • Filing of a pre‑IND or IND with the FDA for a broader nucleosome panel.
  • A strategic partnership with a larger diagnostics manufacturer that could unlock additional capital.

3. Market Pricing Dynamics

The purchase price of $0.28, slightly below the market, indicates a tactical acquisition during a period of reduced volatility. This opportunistic buying may reflect insider confidence that the share price under‑prices the company’s long‑term value, rather than a response to short‑term hype (the company’s high buzz score of 1,790 % is coupled with neutral sentiment).


Historical Trading Patterns of Rootsaert

  • 2025 Sales: 8,519 shares sold at $0.49–$0.77, capturing gains during modest price appreciation.
  • 2026 Purchase: 28,200 shares acquired at $0.28 following a slight correction, suggesting a belief that the shares are undervalued.

Rootsaert’s overall strategy appears to be a gradual accumulation, balancing liquidity needs with long‑term investment in VolitionRx.


Risk Assessment for Healthcare Professionals and Investors

Risk FactorExplanation
Negative EarningsThe company reports a loss, reflected in a P/E ratio of –1.28; profitability remains uncertain until a product reaches market.
Low LiquidityTrading volume is modest; large orders could move the price.
Regulatory UncertaintyApproval of blood‑based diagnostics requires extensive data; delays could impact valuation.
Social Media VolatilityHigh buzz scores can lead to rapid price swings unrelated to fundamentals.

Bottom Line

Insider buying by senior executives, particularly the secretary, signals management confidence in VolitionRx’s near‑term prospects. The coordinated purchases, occurring shortly after a successful Phase II trial and a recent funding round, may presage a regulatory filing or a strategic partnership that could unlock further growth. Nonetheless, the company’s negative earnings, low liquidity, and regulatory pathway underscore the inherent risks. Healthcare professionals and institutional investors should monitor upcoming clinical data, FDA communications, and partnership announcements closely to gauge whether the current insider enthusiasm translates into tangible commercial success.
