Edward M. Giles

Edward M. Giles is a declared insider at 2 companies; the most frequent names are Yield10 Bioscience, Inc. and Ventana Medical Systems Inc. Over a trading history stretching from 28 September 2002 to 24 May 2011, the count stands at 58 filings.

On the open market, the record shows 1 purchase worth €72k and 18 sales worth €5.1M. Netting one side against the other leaves €5.1M of net selling. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. The rest of the record consists of 3 share grants and 3 option exercises. Since January 2011: 1 purchase and no sales on the market.

The newest entry dates from 26 May 2011: an open-market purchase of €72k, in Yield10 Bioscience, Inc. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification.
