Shares of Vanguard Health Systems are up more than 3 percent in Wednesday trading after Deutsche Bank analyst Darren Lehrich said the company is "among the most forward-thinking" when it comes to doing business in the health care reform era. Vanguard's plans to expand its insurance options — we've written about them on several occasions — are promising, said Lehrich, who upgraded Vanguard (Ticker: VHS) to 'buy' from 'hold' and raised his price target to $17 from $14.
