Real time insider trading transaction history:

  • Insiders are prohibited from making short-swing profits by trading their shares within 6 months of the registration or acquiring the shares.
  • Shares are not adjusted for stock split.
"Insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise"
- Peter Lynch
