Gary A. Shiffman, Chairman, President, and CEO, has demonstrated a clear selling bias in his transactions involving Sun Communities, Inc. (SUI), the sole company reflected in his recent SEC Form 4 filings. Over 26 reported trades, his total sales amounted to $24.19 million, dwarfing his $4.87 million in purchases. The most significant sell-off occurred on December 17, 2025, when he disposed of shares worth $19.38 million. By contrast, his largest acquisition was a $4.01 million purchase on March 7, 2025, followed by smaller buys, including a $660,650 transaction on March 4, 2024, and a $199,990 acquisition as recently as February 5, 2026.
Shiffman’s activity suggests a pattern of periodic divestment, with multiple sales in the mid-to-high six-figure range, such as a $721,191 transaction on February 24, 2025, and a $1.50 million sale on January 2, 2024. While he has made occasional purchases, the net outflow is substantial, with his most recent trade—a February 2026 buy—being an outlier amid the broader trend of reducing his position. The filings also include several non-monetary transactions, such as gifts and dispositions, though these do not alter the overall picture of a gradual reduction in holdings. The data reflects a disciplined, multi-year approach to trimming his stake in SUI, with no indication of abrupt or irregular trading behavior.
