How This Insider Purchase Pulse Works

“Purchase” refers to qualifying purchases made by company insiders. An Insider Purchase Pulse is a point-in-time research snapshot of that activity, not a recommendation from MarketWizards to purchase the stock. The Insider Purchase Pulse Date is the date the most recent qualifying insider purchase became public. The report summarizes all qualifying purchases disclosed during the 7-, 30-, 60-, 90-, and 180-calendar-day periods counted backward from the Pulse Date—not backward from today. Purchases disclosed on the Pulse Date itself are also included. When a new qualifying purchase becomes public, it creates a new Pulse Date, and all activity windows and KPIs are recalculated. The previous Pulse remains a historical observation, but its return monitoring closes. A new monitoring period begins from the new Pulse Date so subsequent performance is evaluated against the latest insider-information state.

The report is designed to make the timing, concentration, and scale of qualifying insider purchases across the 180-calendar-day lookback easy to see. It also tracks the stock’s subsequent return and performance relative to SPY from the Latest Pulse Date, helping readers observe how forward performance develops after each disclosed purchase pattern.

Example

For this Jun. 4, 2026 Insider Purchase Pulse, the 30-day lookback covers May 6 through Jun. 4. If another qualifying purchase becomes public on Jun. 11, Jun. 11 becomes the new Pulse Date, the activity windows and KPIs are recalculated, and return monitoring begins again from the new Pulse.

Stock Return After the Pulse Date

Tracks the stock's return after the Pulse Date and compares it with SPY. This chart tracks the stock’s forward returns from the Pulse Date—the date the latest qualifying insider purchase became public—showing how the stock performed after that information entered the public market—not the return earned by the insiders.

Insider Acceleration

Shows whether insider purchasing activity is strengthening across recent, non-overlapping periods. For example, Capital and Buyer Acceleration compare the daily rate in Days 1-30 with Days 31-90; Recent Pulse compares Days 1-7 with Days 8-30. All comparison windows are counted backward from the Pulse Date—not from today.

N/A indicates zero activity in the comparison period, making the denominator zero. The underlying data is complete, but the ratio cannot be calculated mathematically for that specific comparison.

What is a qualifying insider purchase?

A qualifying insider purchase is a reported Form 4 transaction in which a company insider acquires eligible publicly traded common shares using personal capital. Each transaction must pass these controls:

  • Security class: The security must be eligible publicly traded common stock—not preferred shares, derivatives, options, warrants, or another non-common-stock interest.
  • Amendment lineage: Original and amended Form 4 filings are linked so a correction is not counted as an additional purchase.
  • Duplicate event: Repeated disclosures of the same economic transaction are consolidated and counted once.
  • Purchase channel: The transaction must be a qualifying purchase that represents the insider's personal capital commitment.

Private transactions, derivatives, employee-plan acquisitions, option exercises, gifts, sales, and unresolved transactions are excluded. This report therefore focuses only on verified purchases that represent an insider's direct economic commitment to the company.

Research evidence only; not an investment recommendation. Source dates and point-in-time boundaries are displayed so evidence available on the Pulse Date remains distinct from later monitoring.
