Quick look at TRGD and TARM charts shows TRGD (up about 80% in 2010) is being pulled up by TARM (up about 95% in 2010).
This is all due the expectation that 80% of TARM value rolls to TRGD shareholders.
Not rocket science, but:
Of course this means we should see high price movement correlation, that is, whenever TARM moves up or down, we should expect to see TRGD move up or down similarly.
Trivia:
I was thinking that due to the large ownership of TARM by TRGD there may be some tax benefit to TARM or TRGD. For instance if a company(#1) owns at least 40% of company(#2)'s stock, then company(#1) can take credit for their portion of the earnings of company(#2). At least that's the way I understand it based on what I've heard about Hochschild's plans to own at least 40% of GORO.
