If I had a dime for every time I've heard that ... You're thinking risk in terms of flat $$ amount rather than figuring in the probability component. That "little" risk is far higher than you think when you factor in the probability of this "turning on a dime right here."
Fri saw something that hasn't been seen for a while... US markets down over 1% in a session and now 2% off their highs. They are approaching levels that entering longs needs to be considered. My view is that further lows will be seen but some smalls long positions around current levels (DOW support 28,840) might be warranted. EU did not participate in the sell-off but France just announced 2 confirmed cases of the snake flue so expect a gap down on Monday.
A bit of a tug-a-war between the Perma bulls and the realists going on here, Supports have held but I think the realists will eventually win and new lows will be seen. Market's persistence resilience in the face of no good news is getting ridiculous.
