Quote from heilbronner:
is when you get a profit warning in a long position. This happened today with NOK, down almost 20%. No chance to get out, stopp- loss useless in that situation. Portfolio not that much down because of short positions like SAP, YHOO or MDC, but still it hurts.

Quote from margo_trader:
Out of curiosity, why were you long NOK for a swing anyway? I can't find a single reason why anyone would have wanted to own it from a technical view.
Quote from AAAintheBeltway:
You can hedge the overnight risk with options, but at a fairly steep cost, either out of pocket or opportunity. This is probably an area that swing traders need to focus more on though.
