SJT is primarily dry gas and monthly distributions are usually 2 months in arrears. So, we are getting royalties on gas sold 2 months ago. Gas has dropped since then, and give it 6 more months, with declining capex, volumes will taper off with no new wells coming online to offset natural decline, or at least, minimal wells coming online.
Once the reality sets in of $.05/ and $/.06 per month distributions sets in, the price will start to drift down, only tempered by the hope of rising gas prices.
I think if you buy SJT at $10/unit, you will receive a nice yield and have the potential for higher distributions and higher prices when gas rebounds to $3/mcf - $4/mcf. Patience. Wait for it to drop, then have the courage to buy when gas pricing looks its ugliest.
