The pricing structure of the healthcare and drug distribution industry has been wrecked and Wall Street is taking down those stocks as a result, says TheStreet's Jim Cramer. After Thursday's closing bell, the San Francisco-based pharmaceutical distributor McKesson (MCK) - Get Report reported adjusted earnings of $2.94 a share on revenue of $49.96 billion. Analysts were looking for adjusted earnings of $3.04 a share on revenue of $51.21 billion. The company said results were impacted by a "softer pricing environment" in its U.S. pharmaceutical business. Cardinal Health (CAH) - Get Report , which is trading down in sympathy, is set to report first-quarter fiscal 2017 earnings results on Oct 31.
