It was a good day on Wall Street for most Nashville-based publicly traded hospital chains as President Obama's re-election removed uncertainty about the fate of his health care reform law. Sheryl Skolnick, an analyst with CRT Capital in Stamford, Conn., expects a deluge of reform-based regulations from the US Department of Health and Human Services as the Obama administration speeds implementation efforts to prevent having to go to Congress for permission to delay, and giving the House's Republican majority any leverage on reform. Among hospitals chains, Skolnick said HCA and Vanguard Health should benefit the most.
