Here is a detailed roundup of the most prominent insider trading activity disclosed on Wednesday for U.S.-listed companies, covering open market purchases, private trust acquisitions and block dispositions by executives and large shareholders.
Top buys
Star Equity Holdings, Inc. (NASDAQ:STRR)
Jeffrey E. Eberwein - the company’s Chief Executive Officer, a director and a holder of roughly ten percent of the stock - reported multiple purchases that together amount to $56,048 in common equity between June 15 and June 16, 2026.

One specific entry in the filings notes that on September 6, 2022, Ortale, acting through Sewanee Vero LLC - a family trust for which his spouse serves as trustee - acquired 10,000 shares of the 7.50% Series E Preferred at a weighted average price of $20.00, with individual purchase prices between $19.98 and $20.10. At the time of the reported insider buying, FBRT was trading near a 52-week low of $8.12, with the current price recorded at $8.20 in the disclosure. InvestingPro commentary attached to the filing indicates the stock looks undervalued at these levels and that the company offers a dividend yield of 9.76%.

What the filings show and how to read them
The disclosures collected in these filings combine both expressions of confidence and large-scale dispositions. Insider purchases are often interpreted by market observers as a signal of executive confidence in a company’s near-term prospects, while sales can reflect a range of personal financial decisions - including diversification needs, tax planning or use of pre-planned trading arrangements such as Rule 10b5-1 plans. The filings in this roundup include open market buys executed by CEOs and chairpersons, trust-based acquisitions by family vehicles, and multi-million-dollar block sales by founders and investment firms.
Market commentary embedded in the filings - primarily from InvestingPro - assesses relative valuations, points to yields or Fair Value estimates for the securities mentioned, and flags where names trade near 52-week highs or lows. Where such analysis is included in the disclosures, it is noted alongside the transaction detail.
For investors watching insider activity, these filings can serve as one input among many. They document actual executed transactions and reported ownership changes, but they do not provide the full context behind each seller’s or buyer’s motives. As with any single data point, the filings are most useful when considered together with other fundamental and technical indicators.
Key takeaways
- Insider buying was reported at small caps including Star Equity (STRR) and Oncotelic Therapeutics (OTLC), and through a family trust at Franklin BSP Realty Trust (FBRT).
- Large block sales were disclosed at sector-leading names and major holdings, including Applied Materials (AMAT), Arista Networks (ANET), Airbnb (ABNB) and Ingram Micro (INGM).
- Valuation commentary from InvestingPro accompanies several filings, flagging some names as potentially undervalued and others as overvalued relative to Fair Value estimates.
Risks and uncertainties noted in the filings
- Sales recorded by insiders do not establish motive - the filings themselves show disposals executed under pre-planned arrangements and trust vehicles, which may not reflect a change in company outlook. This affects interpretation across sectors including semiconductors, cloud networking and travel.
- Market prices cited in the filings vary relative to InvestingPro Fair Value estimates, introducing valuation uncertainty for investors when assessing the significance of insider purchases or sales.
- Smaller-cap names that saw insider buying also carry sizable short-term price volatility - as noted for Oncotelic Therapeutics, whose stock had declined roughly 16% over the prior week and 51% over six months - creating execution and timing risk for investors considering those signals.
Monitoring these reported transactions alongside company fundamentals, market conditions and valuation metrics can help provide context, but the filings themselves are factual records of trades rather than explanations of intent.
