Congratulation oil lover.
It take some guts to sell it at this level but the life goes on and there are always other opportunities.
About the Pen West Energy and 23% yield: I read the RBC sensitivity study for Canadian Royalties Trusts. PWT.UN require $90 OIL to maintain the monthly distribution.The only Trusts who have sustainable distribution are Zargon, Vermilion, and Trilogy.
With $50 to $60 oil PWT will cut the distribution in half or more. Still 12% is better then nothing. In 2 years PWT will convert to the Corporation but this is out of topic.
