Sabine Royalty Trust (NYSE:SBR) has performed very well compared to other energy trusts since my September article that had a neutral/hold recommendation. Since oil and natural gas prices have declined more than I expected, and I am not bullish on near-term energy prices, I am downgrading SBR to a sell. The monthly distributions for the next few months may remain relatively high because of the multiple months delay between production pricing and monthly distribution payment announcements, but then they will likely decline as they reflect current natural gas and oil prices.
