常见问题
What is Insider Alpha?
Insider Alpha is Blockcircle's live feed of stock trades by US company insiders. It picks up every public insider filing from officers, directors and owners of more than 10% of a company as soon as it is published, and adds cluster detection, per-insider track records, confidence scoring and activist 13D disclosures.
Where does the insider data come from?
Officers, directors and owners of more than 10% of a US-listed company must publicly report when they buy or sell its shares, within two business days of the trade. Insider Alpha picks up each of these insider filings as soon as it is published and turns it into a clean trade record: who traded, their role, the company, the shares, the price and the value.
What is a cluster buy?
A cluster buy is when multiple insiders at the same company file open-market purchases within a short window, typically two to four weeks. Cluster buys have historically been one of the strongest insider-trading signals because they require independent decisions by multiple parties with material non-public information about the company's prospects.
What are activist disclosures?
Activist disclosures are 13D filings, which are required when an investor acquires more than 5% of a public company's shares with the intent to influence corporate governance, strategy, or capital allocation. 13D filings often precede major corporate actions like board changes, spin-offs, or sales.
How does the insider confidence score work?
Every insider in the database has a track record score based on the forward returns of their historical trades. The score weights size, frequency, conviction (purchases on the open market versus 10b5-1 sales), and historical hit rate. Insider Alpha highlights filings from top-decile insiders so you can prioritise the highest-signal filings first.
What is the squeeze view?
The squeeze view ranks tickers by insider buying combined with elevated short interest, looking for setups where insiders are accumulating shares against a high short-interest backdrop - a classic precursor to short squeezes.
