Start with primary filings because fiscal calendars and accounting presentation can make superficially similar quarters incomparable. Both fiscal years end December 31, so annual reports line up, but check segment definitions before comparing growth or margins.
The current verified House and Senate snapshot contains 78 matched transaction rows for GOOG and 89 matched transaction rows for GOOGL. These delayed, range-based disclosures can identify a filing to inspect; they do not establish motive, conviction, or a real-time trading signal.

What this comparison cannot tell you
This page does not contain licensed live prices, a valuation model, earnings estimates, portfolio constraints, or a forecast of future returns. SEC classifications can be broad, company descriptions can lag strategic change, and the latest annual filing may predate a material acquisition or divestiture. Read subsequent quarterly and current reports before making a decision.
A stronger business is not automatically the better stock. Starting valuation, expectations, capital structure, cyclicality, dilution, and the probability of each thesis determine the investment outcome. Use this comparison to frame the work, then verify the numbers in the linked filings and current company disclosures.
