WT President/COO R Jarrett Lilien sold 30,000 shares at $18.99 on 2026-05-20 via 10b5-1 plan; retains 1,110,245 shares

R Jarrett Lilien sold 30,000 shares (30.0K shares) for $569,700.00 ($569.7K) under a pre-arranged 10b5-1 trading plan, reducing his holdings by 2.6% to 1,110,245 shares (1.11M shares). Since the transaction was scheduled rather than discretionary, no timing inference is applicable. Notably, his prior sell at WT on 2026-02-25 saw a 90-day return of +11.6%, meaning the stock subsequently appreciated after that sale. WisdomTree's fundamentals show negative net income of $-23,131,000.00 ($-23.1M) against revenue of $159,470,000.00 ($159.5M), with the stock trading at a P/E of 48.05 and currently at $19.22, down 3.2% from its 52-week high of $19.85. The continued programmatic liquidation under a 10b5-1 plan should be monitored for any acceleration or plan modifications.

CAO Peter M Ziemba sells 100,000 shares of WT at $19.31; holds 885.7K post-sale

Ziemba sold 100,000 shares for $1,931,000.00 at $19.31 on 2026-05-19, reducing his holdings by 10.1%. The sale occurred when the stock was -3.2% from its 52-week high of $19.85, near elevated valuation levels. His cross-ticker track record shows 3 prior sells with an average 90-day return of -14.3% and a 90-day well-timed rate of 100.00%, indicating his prior sales have occurred before subsequent declines. At WT specifically, his most recent measurable sale on 2024-11-15 returned -14.3% over 90 days, consistent with his broader pattern. The company reports net income of $-23,131,000.00 against revenue of $159,470,000.00 in the latest quarter, with a P/E of 48.05, reflecting elevated valuation relative to profitability. The timing and magnitude of this sale warrant monitoring given the insider's demonstrated pattern of selling ahead of downside moves.

Significance 3

Director PANKOPF acquired 277 shares over 6 months for $3.3K at $11.80 blended avg; modest +0.8% increase to 35.0K holdings.

Tonia L. Pankopf, a director at WisdomTree, made 6 separate purchases totaling 277 shares for $3,267.88 between November 2024 and February 2026. The transactions span an extended period with share prices ranging from $9.26 to $16.94, and the total value ($3.3K) is small relative to her total holdings of 35.0K shares post-transaction. The blended average purchase price of $11.80 compares to the current price of $16.59, representing a modest unrealized gain on this specific tranche. The scale of accumulation (+0.8% vs pre-transaction holdings) and dollar amount suggest routine portfolio activity rather than a concentrated conviction signal.

WisdomTree President & COO Jarrett sold 30,000 shares at $16.84, retaining 1,140,245 shares

Lilien R Jarrett, President and COO, sold 30,000 shares (30.0K shares) at $16.84 on 2026-02-25, a modest 2.6% reduction in holdings that leaves him with substantial ownership at 1,140,245 shares (1.14M shares). The sale occurred below the current price of $17.37 and well below the 52-week high of $17.37, near the peak of recent momentum (90-day change: +57.3%). WisdomTree's fundamentals appear sound with Revenue $125,616,000.00 for the latest quarter, Net income $19,701,000.00, and annual revenue growth of +15.4%, though the P/E of 17.72 reflects elevated market expectations relative to recent earnings. The minimal holding reduction and continued sizable position suggest this was a routine portion of a large executive stake rather than a confidence-signaling exit.

ETFS Capital Limited sells 3,000,000 WT shares ($34.0M) at $11.34; exits 19.7% of stake to 12.25M shares

ETFS Capital Limited divested 3,000,000 shares of WisdomTree, Inc. at $11.34 on 2024-12-02, realizing $34,020,000.00 and reducing its position from 15,250,000 shares to 12,250,000 shares. The sale occurred near the 52-week high of $12.20 and represents a material reduction of nearly one-fifth of the insider's holdings. The company's fundamentals show mixed signals: annual revenue growth of +15.8% suggests operational momentum, yet the latest quarter recorded a net loss of $-4,485,000.00 against revenue of $113,168,000.00, indicating profitability challenges. The timing of this substantial stake reduction—while the stock trades within 5.7% of its 52-week peak and 30-day momentum is positive at +11.9%—warrants examination of whether the insider's conviction in the company's future prospects has shifted.

CAO Peter M Ziemba sold 100,000 shares of WT at $11.43 (2024-11-15), retaining 948,386 shares post-sale.

Peter M Ziemba, Chief Administrative Officer, sold 100,000 shares at $11.43 on 2024-11-15, reducing his holdings by 9.5% to 948,386 shares. The stock has appreciated 11.7% over the prior 30 days and 19.1% over 90 days, trading near its 52-week high of $11.94. Ziemba's prior two sales at WT (both in August 2023) were both well-timed, with negative 90-day returns of -5.0% and -1.9%, suggesting a pattern of selling before declines at this specific ticker. However, his cross-ticker track record shows a 90-day well-timed rate of 100.00% across 2 prior sells, though with mixed absolute returns (-3.5% average). The company is reporting net losses ($-4.5M) despite strong annual revenue growth of 15.8%, which provides ambiguous context for the sale.

Significance 7

CEO Steinberg buys 67,869 WT shares at $10.84; now holds 9.24M shares, replicating prior well-timed buy from Feb 2024.

Steinberg's $735,652.45 purchase of 67,869 shares on 2024-11-08 mirrors his prior WT buy on 2024-02-13, both executed during relative strength: the current price of $11.63 sits +17.4% over the prior 30 days and +19.5% over 90 days. His track record at WT shows his February buy achieved 90-day returns of +25.9%, demonstrating well-timed entry. With the stock now near 52-week highs (−2.6% from $11.94 peak), this November purchase occurs in a notably different momentum context than the February entry, which came from a depressed position. The CEO's repeated buying pattern across similar timeframes warrants monitoring to determine whether this signals sustained conviction or represents a systematic execution pattern independent of tactical timing.
