It is GameStop's 3rd cluster in three years, and the largest: the biggest before this was $22.0M.

The last time insiders clustered here, in January 2026 (3 insiders, $22.0M), the stock was 3% higher a month later and 9% higher after three months. In April 2025 (3 insiders, $11.1M), the stock was 12% higher a month later and 5% lower after three months. Two cases are examples, not a pattern.

GME is up 18% over the past month and 4% below its 52-week high of $28.02 (the low was $17.87).

One insider buying can mean many things. Several at the same company, within weeks, with their own money, is the insider pattern with the strongest record in the research.

Why insider clusters matter

One insider buying can mean many things. Several insiders at the same company buying within a few weeks, with their own money, is rarer, and it is the pattern with the strongest record in academic studies of insider trading.

How we rate signals
High: a validated insider cluster (several insiders buying within 30 days, no sales since), a CEO, CFO, president or chair buying on the open market, or two independent signals on one stock. Medium: a single insider purchase, a short-dated out-of-the-money options trade, or a 3-year positioning extreme in a major market. Low: dark-pool spikes on their own, and everything else.
