Trust #2 is in the same oil field with much the same terms, etc. I bought both VOC and SDR last July, and have been hit hard. All three SD trusts are down in sinc with the problems Tom Ward is having with shareholders, although they should not be IMHO. The only other reason is concern over future oil and NG prices. Now that the so-called Cliff is just a slippery slope, we should see a recovery in the SD trusts.
VOC's problems are deeper with the messed-up well, but that expense will be absorbed, hopefully.
I think SDT (along with PER from the same people) is the best on that list, so long as the parent SD remains financially healthy. The riskiest one in that list is WHX for reasons you can read on the WHX board if not already aware.
