Significance 7/10

Palo Alto Networks CTO Nir Zuk sold 100,000 shares at blended avg $172.80 on 2025-08-01 ($17.3M); stock now -18.8% from 52-wk high.

Nir Zuk, EVP and Chief Technology Officer of Palo Alto Networks, executed 8 separate sales totaling 100,000 shares for $17,280,449.86 on 2025-08-01 at prices ranging from $169.11 to $175.63, with a blended average price of $172.80. This reduces his holdings from 3.24M shares to 3.14M shares—a 3.1% reduction. The timing of this sale is notable: the stock traded from $169.11 to $175.63 during execution, but has since declined to a current price of $169.09, marking an -18.8% retreat from its 52-week high of $208.28 and a -16.2% drop over the prior 30 days. His same-ticker history at PANW shows five prior sells on 2025-07-01, all of which registered significant negative 30-day returns (-11.3% to -14.8%), establishing a recent pattern of selling into weakness at this company. While his cross-ticker track record spans 20 prior open-market sells with a 37.50% well-timed rate and a positive average 90-day return of +8.6%, the more immediate PANW-specific pattern suggests recent insider sales have preceded further declines in the stock.

Significance 6/10

CTO Zuk Nir sells 100,000 PANW shares for $19.9M across 9 transactions on 2025-07-01

Zuk Nir, EVP and Chief Technology Officer, executed 9 separate sales totaling 100,000 shares (100.0K shares) for $19,866,061.27 ($19.9M) across a narrow price range ($195.66–$201.91) on a single day, reducing his holdings by 3.0% from 3,343,516 shares to 3,243,516 shares. The multi-tranche structure at incrementally higher prices within a tight band suggests a systematic, potentially pre-planned liquidation rather than opportunistic selling. His cross-ticker track record shows 20 prior sells with an average 30-day return of +9.9%, but PANW-specific outcomes are sparse and recent: five prior sells at this ticker (all since May 2025) showed modest 30-day returns (1.4%–2.8%), though 90-day outcomes remain unmeasurable. The stock currently trades at $201.82, near the top of its 52-week range ($147.09–$208.28) and 3.1% below its 52-week high, after a strong 90-day rally of +31.4%. The sale's timing—at elevated price levels following substantial recent appreciation—warrants monitoring given the company's stretched P/E of 108.51 relative to quarterly revenue of $2,289,000,000.00, though the absence of timing precision in prior PANW sales limits conclusions about forward predictiveness.

Significance 4/10

CTO Nir Zuk sold 100,000 shares of PANW for $19.3M at blended $193.36; remains 3.34M shareholder

ZUK sold 100,000 shares (-2.9% of pre-transaction holdings) across three transactions on 2025-06-02 at prices ranging from $192.62 to $194.33, capturing $19,336,476.76. His remaining 3,343,516 shares represent a continued substantial equity position in PANW. The sale occurred at prices near but below the current market price of $197.12, and his cross-ticker track record shows an average 90-day return of -50.6% following his prior sells (well-timed rate 100.00%), suggesting a historical pattern where his sales have preceded price declines. At PANW specifically, his most recent prior sales on 2025-05-01 and 2025-04-11 have shown positive returns in their measurable 30-day periods (+1.9% to +12.7%), though 90-day outcomes are not yet determinable. The stock has risen +5.0% in the past 30 days and +7.0% in the past 90 days since this filing date, sitting -5.4% from its 52-week high.

Significance 5/10

PANW CTO Nir Zuk sells 100,000 shares (100.0K) for $18.8M on 2025-05-01 at blended avg $187.80

Nir Zuk, EVP and Chief Technology Officer of Palo Alto Networks, executed three separate sales totaling 100,000 shares (100.0K shares) for $18,780,392.43 ($18.8M) on 2025-05-01, representing a 2.8% reduction of his 3.54M share pre-transaction holdings. At a blended average price of $187.80, the sales occurred near the current price of $188.13 and within the 52-week range; the stock is 9.7% below its 52-week high of $208.28. His cross-ticker track record shows a 100% well-timed rate on sells with an average 90-day return of -50.6%, indicating his prior open-market sales have historically been followed by stock declines. However, at PANW specifically, his 5 prior trades from 2025-04-11 do not yet have measurable outcomes. The fundamental context shows revenue growth of 16.5% year-over-year with a P/E of 99.54, situating the company in a high-valuation regime despite solid top-line momentum.

$107,489,823
Significance 8/10

PANW CTO Zuk Nir sells entire 649,828 share position for $107.5M on April 11, 2025

Zuk Nir, EVP and Chief Technology Officer of Palo Alto Networks, executed 16 separate sales totaling 649,828 shares for $107,489,822.56 at a blended average price of $165.41, completely liquidating his holdings in the company. This full-position exit by a senior technology executive differs materially from typical portfolio adjustments given its scale and the fact that all 649.8K shares were sold. Notably, Nir's cross-ticker track record shows a 100.00% well-timed rate on his prior 20 sells with an average 90-day return of -48.6%, and his 5 prior sales at PANW (all on 2024-11-25) demonstrated similar patterns with 90-day returns ranging from -50.5% to -51.7%—all well-timed. Since the sale, the stock has declined 6.8% over 30 days and is trading at $169.98, down 18.4% from its 52-week high of $208.28, consistent with the historical timing pattern on this ticker. Investors should monitor whether subsequent quarters reveal fundamental deterioration that would explain this complete exit by a key technical leader.

Significance 6/10

Palo Alto Networks CTO sells 168,000 shares for $65.1M at blended average $387.39; prior 5 PANW sales showed 30d declines averaging -46.6%

Zuk Nir, EVP and CTO of Palo Alto Networks, executed 12 separate sales totaling 168,000 shares for $65,081,831.10 on 2024-11-25 at prices ranging from $383.95 to $395.79. This represents an 8.4% reduction in his holdings, bringing them from 1,989,758 to 1,821,758 shares post-transaction. Notably, the insider's recent trading pattern at this ticker is striking: his 5 prior sales at PANW (all on 2024-10-01) each showed negative 30-day returns, ranging from -45.8% to -47.3%, suggesting these earlier exits preceded share-price weakness. His cross-ticker track record shows 20 prior sells with an average 30-day return of -48.7%, indicating a consistent pattern of selling before subsequent declines. The current stock price of $198.20 represents a 50% loss from the blended transaction price of $387.39, raising questions about whether this latest filing reflects similar predictive timing or whether the stock's broader decline has other drivers.

Significance 6/10

PANW CTO Zuk Nir sold 36,000 shares on 2024-10-01 for $12.0M at blended avg $332.50; current price $167.97 (-49.4% from sale).

CTO Zuk Nir executed 13 separate sales totaling 36,000 shares for $11,969,838.97 on 2024-10-01, reducing holdings by 3.1% to 1,115,567 shares. The sales occurred across a narrow price range ($329.27–$340.57), suggesting a systematic liquidation rather than opportunistic trading. His prior trades at PANW show a consistent pattern of poorly-timed sales: all five recent sales on 2024-09-03 recorded 30-day losses ranging from -52.8% to -53.8%, and the current price of $167.97 is -49.4% below the blended sale price of $332.50, indicating this October sale has also declined sharply. With cross-ticker track record averaging -48.7% 30-day returns on 20 prior sells, this insider's historical timing record shows alignment with the current negative outcome, suggesting a pattern rather than a one-time misjudgment.

Significance 6/10

CTO Zuk Nir sells 36,000 PANW shares for $12.9M at blended avg $359.17 on 2024-09-03; retains 1.15M shares.

Nir executed 11 separate sales totaling 36,000 shares for $12,929,955.82 at prices ranging from $355.28 to $363.53, reducing holdings by 3.0%. His cross-ticker track record shows a 90-day well-timed rate of 100.00% across 20 prior sells with avg 90d return -50.3%, but his same-ticker history at PANW (5 prior sells on 2024-08-01) shows no measurable 90-day outcomes yet, with recent 30-day returns ranging from -42.2% to -44.2%. The current price of $170.90 is 9.3% below the 52-week high and down 5.8% over 30 days, representing substantial declines since the September transaction at $359.17. Nir's substantial remaining position of 1.15M shares suggests continued material stake in the company despite this liquidation activity.

PANW CTO sold 36,000 shares ($11.4M) on 2024-08-01 at avg $317.77; stock down 18.9% from 52-week high, current $152.80.

Nir executed 13 separate sales totaling 36,000 shares for $11,439,762.21 on August 1, 2024, reducing holdings from 1.22M to 1.19M shares (-2.9%). The blended average sale price was $317.77. The stock has since declined sharply: it currently trades at $152.80, down 18.9% from its 52-week high of $188.45, and has fallen 10.4% over the prior 30 days. Nir's same-ticker history at PANW shows 5 prior sell transactions all executed on 2024-07-01, each producing negative 30-day returns ranging from -51.3% to -52.3%; the 90-day outcomes remain unmeasurable for those July trades. His cross-ticker track record across 20 prior sells elsewhere shows an average 90-day return of -45.2%, with a 100% well-timed rate (all sales preceded stock declines), yet this statistical edge has not extended to measurable outcomes at PANW itself. The current price of $152.80 represents a 51.9% decline from the August 1 transaction prices, suggesting these sales occurred near a significant peak in the stock's trajectory.

Significance 6/10

PANW CTO Zuk Nir sells 36,000 shares for $12.2M; latest trade in series of six PANW sales since June

On 2024-07-01, Zuk Nir, EVP and Chief Technology Officer at Palo Alto Networks, executed 10 separate sales totaling 36,000 shares for $12,209,676.04 at prices ranging from $332.40 to $341.29. This is his sixth concentrated sell event at PANW within a month; he also sold on 2024-06-03 (four separate transactions the same day). His post-transaction holdings remain substantial at 1,223,567 shares. Notably, his prior five PANW sales on 2024-06-03 all showed steep 30-day declines (between -41.6% and -42.5%), yet the current stock price of $170.60 is down -9.5% from its 52-week high and reflects a sharp reversal after the June sales. The frequency and size of these dispositions—six trading days apart with consistent multi-tranche execution—warrant attention to whether material developments are influencing the CTO's portfolio decision-making or whether these follow a predetermined schedule.
