John L. Castello

John L. Castello is a declared insider of Cholestech Corporation, with filings sourced from SEC (Form 4). The record holds 5 filings, for trades running from 16 August 2006 to 12 September 2007.

The filings describe grants, exercises and other transfers rather than trades on the open 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 newest entry dates from 13 September 2007: a transaction, in Cholestech Corporation. Typically, a trade is published a median of 3 days after it takes place. The legal deadline for a Form 4 is two business days after the transaction. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
