RE:TRX vs. CPHCph used a tax asset which makes they're PE look better than it actually is on a trailing basis. They also have an overhang in regards to one of their patents being challenged on their lead derma drug in the US. Trx is a much better place to be right now even at current levels given all of the recent developments. To each their own though, PE can be very misleading sometimes, i rarely look at it as a metric to base a buy on.
