If I had my account at TRP, PRNEX is one of funds I would hold for long term. Most of NR funds did better than S&P during the last 9 years (only very selected funds did better in 1998). NR is the bottom of the food chain. Another TRP fund I like to hold for long term is PRLAX. KM
Disclaimer: I don't own neither but I own other NR and LA funds.
