All filings by Tao Zhang on record concern Hoku Scientific Inc. The record holds 5 filings, for trades running from 1 June 2011 to 31 March 2012.

The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.

The record was last updated on 3 April 2012 with a share grant (€4,338) in Hoku Scientific Inc. Typically, a trade is published a median of 3 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
