Hihi what you mean shiny things?
I mean you're talking about selling 20% of the average daily volume of Asia Pay TV Trust. That is
a lot, and it's easily enough to move the market against you as soon as people see you selling.
If you're going to sell that entire lump:
1) Sell it more slowly. Spread it out over a week, unless you see someone on the bid for your entire amount.
2) Don't put all your eggs in one basket. What if APTT announces a profit warning? You've got all your money in one stock and you're going to take a 20% or 30% hit from something you couldn't control.
