You're right, I probably should clarify what I mean by "questionable future". I suppose I mean something relatively short term - say 6 months. You're right, PLS doesn't have a doubtful future, but certainly the next 6 months won't be very cheerful.

My guess is the same for WHC. I said before that $9 was too expensive for what WHC was making and the risks involved. I don't short though, because the market can behave irrationally for a long time.

WHC certainly won't go bust, but, as @Jonnyash says, the costs are rising, the sale price/s have/are decreasing, that means slimmer margins, less dividends. Again, this might be short term. But why take the risk when HISA are paying ~4.5% risk free? If you bought at the $9, you're down ~25% or at least 5 years of dividends.
