Goldsteen Mitchell B. has demonstrated a consistent selling bias in recent SEC Form 4 filings, with no recorded purchases across 38 transactions totaling $922,648.86 in sales. The activity is concentrated entirely in shares of Shimmick Corporation (SHIM), with 25 sales executed between July 2025 and March 2026. The largest single transaction occurred on March 17, 2026, when Goldsteen sold $357,500 worth of SHIM shares—nearly 40% of the total sold value in the reported period. Prior sales were smaller but frequent, with multiple transactions occurring in tight clusters, such as the $306,640.87 sold across 11 trades between August 4-29, 2025, and another $124,876.36 across 10 trades in late July 2025.
The pattern suggests a prolonged divestment from SHIM, with sales ranging from modest amounts like $1,728 on July 21, 2025, to more substantial transactions like the $68,695.15 sale on August 15, 2025. The absence of any buys—both in recent filings and across the entire dataset—indicates a one-directional reduction in exposure. While the reasons for the sales are undisclosed, the frequency and persistence of the transactions highlight a clear dispositional trend rather than isolated portfolio adjustments. The activity does not extend to other companies, making SHIM the sole focus of Goldsteen’s reported insider transactions.
