Questions
Where does insider trading data come from?
From SEC Form 4, which officers, directors and 10% owners file within two business days of a trade.
Is insider buying a good signal?
Purchases with their own money are the clearer signal; sales happen for many reasons. It is one input, not a reason to buy on its own.
How much does Investingly cost?
The Free plan costs nothing. Pro is $30 a month or $240 a year, and new accounts get 7 days of Pro without a card.
