Nancy Masten

Nancy Masten has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Markwest Energy Partners L P and Markwest Hydrocarbon Inc. Activity is concentrated on a single trading day, 31 January 2006, with 2 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 latest filing, published on 2 February 2006, reports a share grant in Markwest Hydrocarbon Inc. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
