PRIS and Carlos Slim

On November 1, 2011, I wrote that PRIS was trading below $4 and was worth more than that, so long as Europe didn't return to the Dark Ages.  It seems that Carlos Slim agreed with me.  Slim's Carso SA announced today that it bought 3.2% of PRIS.  The stock has responded, up almost 17% today alone and roughly 20% from its closing price on November 1.  Hope you got into PRIS.  I did -- I like to put my money where my mouth is.  I bought it at $3.73.
