William D. Claypool MD

All filings by William D. Claypool MD on record concern Viropharma Inc. Between 8 May 2006 and 24 January 2014, the trades on record add up to 61 filings.

Market trades split into 13 purchases (€200k) and 37 sales (€1.9M). The net balance comes to €1.7M on the selling side. Open-market purchases are the filings investors watch most closely, because the insider pays for the shares out of pocket. The rest of the record consists of 2 share grants and 8 option exercises.

Half of the purchases are above €8,289 and half below.

Most recently, on 28 January 2014, the filings show a transaction worth €1.8M in Viropharma Inc. The clock since the last published purchase (27 February 2009) now reads 6,448 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
