Vanderhook Christopher, Chief Operating Officer, has demonstrated a consistent pattern of selling activity in DSP (Viant Technology Inc.) shares, with no recorded purchases across 26 reported transactions. Since September 2025, Christopher has executed sales totaling approximately $4.22 million, with the largest single disposition occurring on September 17, 2025, valued at $3.00 million. The sales have been methodical, often clustered in multi-day sequences—such as the $152,300 sold across January 20–22, 2026, and the $172,200 disposed of between March 17–19, 2026. Smaller transactions, like the $29,475 sale on December 19, 2025, and the $30,074 sale on February 19, 2026, suggest ongoing liquidation rather than isolated events.
The filings also note derivative transactions coded as dispositions (D) and acquisitions (M), though these entries reflect zero-dollar values, indicating they may involve non-monetary adjustments like option expirations or transfers. Christopher’s activity is exclusively tied to DSP, with no trades reported in other securities. The absence of buys and the recurring sell-side transactions—particularly the concentrated disposals in Q1 2026—point to a deliberate reduction in exposure. The pattern aligns with a broader trend of net divestment, though the reasons remain undisclosed in regulatory filings.
