You might want to also look at CGMFX also which although they are both similiar in energy but when real estate becomes a better investment they will differ. The same manager for both. Perhaps you might want to have a little of both.
Same Sentiment. As a long-time investor with CGMRX, I feel exactly the same as you do. The global demand for energy will continue to increase and people will always need a place to stay; therefore, I am buying CGMFX & CGMRX monthly. During the last 5 years, these funds have helped me to send a child to college and also improve my bottom line considerably.
