Sometimes ...There is no rhyme nor reason for a stock to go up. Its the hysteria that causes it based upon the potential of such a stock. I remember in the summer of 2008 GXS went from pennies to almost $20 ... they had found metres of coal. Area plays were on fire too.
IMO, the hysteria around INT is from equating its growth to double that of facebook when facebook first started. Look at face book now - worth BILLIONS. Its that potential/speculation that has buyers lining up for INT. Call it a mania, a bubble or whatever you like, but IMO INT will probably go much much higher. The trick, I guess, is knowing when to sell.... BUT greed usually gets most people ....
As of now, I think (I could be wrong) that INT will probably go into the dollars .... I had bought in @ .11 ... sold that and am now playing with profits. Bring on the tulip craze!!! LOL
