What is Insider Trading on Block Inc.?

Legal insider trading occurs when executives, directors, and major shareholders (>10%) of a public company buy or sell shares of their own company and report it to the SEC via Form 4.

How to Read the Data

Open market purchases (P) — the strongest signal. The insider uses their own money to buy shares.

Signals to Watch for SQ

Cluster buying: multiple Block Inc. insiders buying in the same week → very bullish signal
Excessive selling: selling volume above historical average → possible concern signal
Form 144: filing of a sale notice → imminent sale in the coming days/weeks
10b5-1 Plan: pre-programmed sales are less significant than discretionary sales
