When economy bottoms out, how will we know?

But the economy always recovers. It runs in cycles
I always thought economists make it run in cycles, they make sure it gets inflated and a bubble gets created and watch it blow up

None of them expects it to come anytime soon.
But it is president's responsbility to say we are going to see recovery by this year's end

HOW MUCH WORSE COULD IT GET? The darkest days for the job market are almost certainly still ahead
We have not even met the dark days yet, we have to reach dark days and then darkest days, we have a long long long way ahead

HOW BAD IS IT?: The median price of a home sold in the United States fell to $170,300 in January, down 26 percent from a year and a half earlier, according to the National Association of Realtors
We are hoping for a correction of atleast 50 percent in india, things have become very inflated here

Jack Ablin, chief investment officer at Harris Private Bank in Chicago, said the Dow could fall to 6,000 if the economy slows much further and unemployment rises well past the current 8.1 percent.
How is the article so incoherent, above it says economists feel we see unemployment touch 10% but there is again an if here, maybe CIO of harris private bank isn't an economist who tries to think ahead.
Anway it means we are going to see dow touch 5000 odd levels, as we are sure of hitting higher unemployement rates
