Bob R. Simpson, an insider at TXO Partners, L.P. (TXO), added another 125,000 shares to his position on August 13, 2026, paying $14.32 apiece for a total outlay of $1,789,787.50. The purchase was made on the open market, meaning Simpson used his own funds rather than acquiring shares through options or other compensation arrangements. Following the transaction, he holds 9,500,000 shares directly.
This latest buy is not an isolated event. It is the fifth open-market purchase by Simpson in a one-week span, running from August 7 through August 13, 2026. Taken together, the five transactions total $5,638,175 in stock bought directly on the market. Our system classifies this latest filing as a cluster buy, reflecting the repeated, concentrated nature of the purchases rather than a single one-off transaction.
A Pattern That Keeps Growing
We first flagged this activity earlier in the month. As detailed in our earlier report, TXO Partners: Simpson Buys $1.4M, Part of $3.5M Cluster, the cluster had already reached $3.5 million as of August 11. In the two days since, the total has grown by more than $2 million, with this newest 125,000-share purchase pushing the running sum to $5,638,175 across five separate filings.
The consistency of the buying — same insider, same company, repeated purchases within a tight window — is what distinguishes a cluster buy from a routine single transaction. Each disclosure on its own might be viewed as a modest data point. Strung together, the five purchases paint a picture of sustained, deliberate accumulation over a short stretch of trading days.
Why Cluster Buys Draw Attention
Academic research on insider trading has repeatedly found that clustered purchases by insiders — multiple buys from the same person or across multiple insiders at a company within a short period — tend to correlate with above-average stock performance in the months that follow. That correlation is a statistical pattern observed across large datasets of filings, not a guarantee tied to any individual company or transaction.
This article reports solely on what has been disclosed in TXO Partners’ SEC Form 4 filings. Simpson’s total direct ownership now stands at 9,500,000 shares, and the string of purchases spanning August 7 to August 13 remains the notable thread connecting this filing to the two prior ones. Readers interested in tracking whether the pattern continues can watch for future disclosures as they are filed with the SEC.
