Black Swan Events

[Adamus]

Time for a suitable quote perhaps:

If you play a game with unlimited liability, you will go broke with a probability that approaches certainty as the length of the game approaches infinity. -- Ralph Vince, Mathematics of Money Management.

---where 'a game with unlimited liability' = 'futures'

Admittedly, if you go long, your liability is not unlimited, just extreme, whereas going short gets you full unlimited liability.

had something akin to that fat finger today on short sterling...

I was rather grateful
