UK Investment SIPP blog for the longer term

Sorry, I’ve not had time to update this blog recently, but I have some great news. I have nearly achieved the 50% increase in my portfolio and it’s only 5 months in
 - I started my SIPP on the 17 July 2006. My SIPP value is now £26,700 and I started with £18,850 - an increase of 42% - £7850. My main holdings at the moment are RCG, AMU and TAN.
I would like to add other stocks, but I find they are very hard to identify. AMU is a turnaround, currently valued at a forward PE of 5, RCG is a super growth story with undervalued characteristics
and TAN is a UK zero emmision electric vehicle company, with solid fundamentals and in a theme that should provide the next big investement bubble - environment. If you know of other solid environmental stocks please let me know.
If my investments keep rising like this, then watch out Warren Buffet, I’m on your tail.
