er.. no sifu here, just thinking out loud & bouncing some ideas off U ya.
1. IF U cut loss now, do U have anything better to plonk the $ in?
2. IF U didn't cut loss now, can U hold for 5 to 10 years? ie. don't need the $
3. IF U held for 5 years, what are your expectations? 5%pa compounded? 7%pa compounded? 9%pa compounded? 12% pa compounded? 20%pa compounded?
IF (1), why not?
IF U don't have anything better with higher probability.. continue to below
IF (2) and for (3) U expect around 5%pa to 9%pa, ok ar - statistically probable as LOOOONG term stats (we're talking about 10 years and more) i saw from PM's statistical FPAdvisor shows those ranges. Poke your favourite PubMutual agent for more details/print out (to PDF).
IF (2) and for (3) U expect 15%pa to 20%+pa... er... good luck with timing the market.
Just a thought

BTW, in future, U may want to have some % overseas.
Personally, i'm aiming for 2/3 or more of my investment assets to be overseas (in more than 2 countries).
Thanks bro for simple and meaningful insight... I am looking to involve in overseas as well (europe and china) reading the direction of growth over there.
Still my sense said to maintain on local equity and little bit exposure to asia ex-japan.
