Eric Sirota

All filings by Eric Sirota on record concern Optimer Pharmaceuticals Inc. Over a trading history stretching from 9 May 2013 to 24 October 2013, the count stands at 3 filings.

Not one of the filings records a straightforward purchase or sale on the market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.

The legal deadline for a Form 4 is two business days after the transaction. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
