Depreciation / Speculation

Difficult choice...

Do I wait until Friday morning to buy my tricolour rear mirror condoms, when they should be half the price again (they were EUR6 last Saturday...)

Or do I buy in bulk now and resell at EUR9 after Ireland has defeated Spain? (BS's belief)

Buy? Sell?
It's all too complicated. I'd rather manage a hedge fund and not worry about the consequences...
