This one tumbled more than 40% on Wednesday due to Federal investigation of unlawful collection practices on medical fees. Thurs - up more than 10% in the morning but retreated in the afternoon to a 52 week low @ $10.50. Even with the drop, the PE is still 30+ and book value is $2-3. Surely the stock is still not "cheap". Any thoughts on this? Shorting opportunity or long buying opportunity for the bounce? I'm in the first camp due to the price action but has some reservations that the drop is overdone. Another stock which recently took a beating is YPF due to Federal expropriation of the majority stake (51%) from Spanish Repsol. Opinions are welcome.
