Activist 13D/13G Filings - WESTFIELD CAPITAL MANAGEMENT CO LP

Real time Form 13D and 13G transaction reports:

  • Schedule 13D must be filed within ten days after a person or an organization acquires beneficial ownership of more than 5% of a voting class of a company's equity securities.
  • Due to inconsistent filing format, it is highly recommended that you read the orignal filing form.
  • 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"
