I think it all depends on your perspective. If you are looking for what profit (or loss) you can make in the next month, then yes, it is a crap shoot. But if you are looking 6-12 months out I think the US markets, at least, will be in a better place. Maybe/probably even better than they were a month ago at new tops.
My timeframe is 6-12 months at the short end, and 5 years + on the long end. So I am looking at this as an opportunity to put some of the profit I took this past summer back into the equity marketplace. I do believe bonds will do well in this crisis, but that is short term trading, and I don't do that. long term bonds can only fall.
I also have 99% of my portfolio in mutual funds. So I don't pick individual stocks. I pick market sectors (e.g. large cap, small cap, tech, health, international, etc.) and let the experts runnign those funds do the stock picking within their specialty. This also lowers my risk profile due to diversification.
Now Europe or Asian markets - well I think that still needs to be shaken out some.
That being said, I see this dip as an opportunity, not a catastrophy.
