Significance 5/10

CAO Mark Peterson sold 35,267 shares of ZWS at $51.80 for $1.8M, reducing stake by 9.4%

Peterson sold 35,267 shares at $51.80 on 2026-02-10, near the company's 52-week high of $52.78 (-2.0%), while the stock has gained 12.5% over the past 30 days and 8.9% over 90 days. His same-ticker history at ZWS shows mixed outcomes: 1 of 4 prior measurable sales were well-timed at the 90-day mark, with prior 90-day returns ranging from -2.7% to +11.4%. His cross-ticker track record shows a 28.57% well-timed rate across 8 prior sales. This sale occurs in a favorable pricing context relative to recent momentum, but Peterson retains substantial exposure with 339,613 shares post-transaction in a company posting solid fundamentals ($455.4M quarterly revenue, +8.3% annual growth, P/E of 37.49).

Significance 4/10

CAO Mark W Peterson sold 23,183 shares of ZWS at $51.40 on 2026-02-05 for $1,191,606.20

Peterson sold 23,183 shares (-7.3% of pre-transaction holdings), reducing his position from 318,561 to 295,378 shares at a transaction price of $51.40. The stock currently trades at $52.78, near its 52-week high of $52.78 and up 14.3% over the past 30 days. At ZWS specifically, Peterson's prior 4 measurable sales show mixed timing outcomes: one sale (2025-07-31) achieved +11.4% over 90 days post-sale, while another (2024-11-07) resulted in a -2.7% 90-day return; overall, only 1 of 4 prior ZWS sales was well-timed at the 90-day mark. Fundamentally, ZWS trades at a P/E of 45.90 with recent quarterly revenue of $455,400,000.00 and net income of $61,800,000.00, reflecting a high valuation multiple on modest annual revenue growth of +2.4%.

Sell
21,570 shares
$1,045,714
Significance 5/10

Chief Administrative Officer Mark Peterson sells 21,570 ZWS shares at $48.48; stock now at $46.08 (-4.3% from 52-week high).

Peterson sold 21,570 shares at $48.48 on 2025-11-12, representing a 6.3% reduction in his holdings to 318,561 shares post-transaction. The sale occurred near the 52-week high, with the stock currently trading at $46.08. Examining his prior trade outcomes at ZWS specifically: his 5 preceding trades show mixed timing, with a 90-day well-timed rate of 1 of 4 measurable outcomes—meaning only 1 of his 4 prior 90-day sell sequences resulted in stock declines after the sale. His broader cross-ticker track record shows a 90-day well-timed rate of 40.00% (6 prior sells), indicating below-average precision at timing market peaks. The transaction reduces concentration but does not signal a clear directional conviction given the modest timing accuracy demonstrated both at this ticker and across his broader trading history.

Significance 4/10

Peterson sells 20.3K ZWS shares at $46.44; still holds 340.1K; 5th sale in 2+ months at firm

Peterson, Chief Administrative Officer, sold 20,349 shares at $46.44 on 2025-08-27, generating $945,007.56 in proceeds while retaining a substantial post-transaction holding of 340,131 shares. At ZWS specifically, this represents his fifth open-market sale in approximately four months (dating back to 2024-02-08), with his most recent prior sale on 2025-07-31. The stock is currently trading at $45.36, near the 52-week high of $46.55, having risen 25.3% over 90 days. His cross-ticker track record shows 5 prior sells with a 50.00% well-timed rate at the 90-day mark (avg 90d return +0.4%), while at ZWS specifically, 2 of 4 prior measurable sales proved well-timed. The pattern of repeated sales over a compressed timeframe at a single holding, combined with current valuation near 52-week highs, merits observation but does not yet signal material deterioration in the underlying business (revenue $444.5M, net income $50.5M, P/E 43.62).

Sell
22,138 shares
$953,041
Significance 5/10

ZWS Chief Administrative Officer Mark Peterson sells 22,138 shares at $43.05 (Jul 31, 2025); holds 360,480 post-transaction as stock hits 52-week high of $44.98.

Peterson sold 22,138 shares (−5.8% of pre-transaction holdings) at $43.05 on 2025-07-31, reducing his stake from 382,618 to 360,480 shares. The current price of $44.98 is now at the 52-week high with a 30-day gain of +19.8% and 90-day gain of +28.6%, indicating strong recent momentum. Historically, Peterson's cross-ticker track record shows 4 prior sells with a 50.00% well-timed rate at the 90-day mark and a concerning avg 90d return of +0.4%, suggesting his sells have been poorly timed on average—the stock has typically risen after his exits. At ZWS specifically, 2 of 4 prior sells were well-timed (showed negative 90-day returns), but the most recent ZWS sells in November 2024 showed mixed outcomes (+3.2% and +9.7% at 30 days, suggesting he missed near-term gains). The sale occurs as ZWS trades at a P/E of 43.25 with modest annual revenue growth of +2.4%, leaving open whether this transaction reflects a valuation concern or personal portfolio management.

22,203 shares

Significance 4/10

CAO Mark Peterson sold 22,203 ZWS shares at $39.15; stock recently +8.7% (30d), trading near 52-week high of $39.91.

Peterson sold 22,203 shares (22.2K shares) for $869,247.45 ($869.2K) on 2024-11-07 at $39.15, reducing his holdings from 406,113 shares to 383,910 shares (-5.5%). The transaction occurred as ZWS stock has rallied +8.7% over 30 days and +29.2% over 90 days, with the current price $39.19 only 1.8% below the 52-week high of $39.91. Peterson's cross-ticker track record across all open-market transactions shows 3 prior sells with a 90-day well-timed rate of 50.00%, indicating mixed timing performance. At ZWS specifically, his prior two measurable sells (2024-02-08 and 2024-02-09) each showed negative 90-day returns of -2.3% and +0.6% respectively, with 1 of 2 prior sales at this ticker being well-timed at the 90-day mark. The company's fundamentals remain solid with $410.0M quarterly revenue, $43.5M net income, 19.4% annual revenue growth, and a market cap of $6.7B, though the P/E of 48.38 reflects elevated valuation.
