MarkWest Energy (MWE +1%) lags the general market after posting mixed Q2 results yesterday. Net profit more than doubled, but the surge in gains was derivatives-based, which masked a decline in other revenue. Revenue from its Southwest segment - its biggest top-line contributor - decreased by 20% as operating income fell 14%. Its Northeast segment, which should be benefiting from strong exposure to the Marcellus shale region, declined by 22%, while operating profit also fell 22%.
