Vanderhook Timothy, CEO and Chairman of DSP (NYSE: DSP), has demonstrated a consistent pattern of selling activity over recent months, with no recorded purchases in the same period. Since September 2025, Vanderhook has executed 13 sales totaling approximately $4.22 million, with the largest single transaction occurring on March 10, 2026, when he disposed of shares worth $463,858.50. The sales have been frequent and methodical, often clustered over consecutive days—such as the three sales between March 17 and March 19, 2026, which amounted to $152,327.37 in aggregate. Earlier transactions followed a similar cadence, including a series in January and December 2025 where Vanderhook sold shares in blocks ranging from $29,475 to $106,529.81 per filing. Notably, the only non-sale transactions in the dataset are marked as dispositions (code "D") or gifts (code "G"), with no accompanying market purchases. The largest disposition, valued at $3 million, occurred on September 17, 2025, though it did not involve an open-market sale. The absence of buy transactions and the recurring sell-offs suggest a deliberate reduction in Vanderhook’s stake in DSP. While the filings do not indicate the reasons behind these transactions, the data reflects a clear directional trend: a steady divestment from his position in the company over the past year.
