Fundamentals and External Factors are Hard to Trade

Here is  cute overview of the relationship between fundamentals and the DOW over at Macrotactics:

GM chapter 11 = PRICED IN
125K+ jobs lost from GM chapter 11 = PRICED IN
unemployment @ 9% = BETTER THAN EXPECTED
unemployment @ 10% = DOW SOARS
unemployment @ 11% = GREEN SHOOT RALLY
unemployment @ 12% = ALREADY FACTORED IN
unemployment = 35% = DOW DROPS 100 POINTS
housing price =1% = RECESSION ENDING
housing collapses = GREEN SHOOT
Housing falls 20% = STABILIZATION
Government spends 1 trillion of OUR dollars = STIMULUS

U.S. debt overwhelming = TOO BUSY RALLYING TO CARE
Consumer stops spending = RETAIL RALLY
Banks are insolvent = SIGNS OF STABILIZATION
American auto industry BK = GOOD THING
Banks pass scam stress tests = HUUUUUUUUGE RALLY
Banks “only need 75 billion = OUT OF THE WOODS
Banks pass a real stress test = NEVER WOULD HAPPEN
Banks pay back tarp = LATE DAY SURGE

OIL @ 100 = IMPORTANT RECOVERY SIGN
OIL @ 20 = TAX BREAK

And the one we should all interpret correctly:
NO ONE IS BUYING STOCKS = BILLIONS ON THE SIDELINES

As much as I would like to think that you can use fundamentals to predict the market, it just goes to show you how difficult they are to use in reality.
