CST whats it really worth

Morn Folks , I've seen some pie in the sky figures on CST and followed the run up several months ago .
I wonder if anyone has put a tangable price on what the company will make in the future ?
So what should i pay for it now ?
Yesterday closed on its low , today made a lower low so i guess just filling in the gaps or a good profit opp for those bottom pickers who got in .
Love to pick up some but prefer to stay with co's which are already making $$$$.
advice welcome . cheers ge
