The markets opened lower this morning and have continued to slide all day, mostly due to poor reports on manufacturing and unemployment. Still, for the third quarter both the DJIA and the S&P 500 indexes gained about 15%. Now, it appears that faith in an economic recovery is wobbling, primarily as a result of expected growth in unemployment and continuing low consumer spending. The federal stimulus program has pumped about $86 billion into the economy so far, but that hasn't been enough to shake loose tight-fisted lenders or cash-conserving consumers.

Here are the numbers::

Dow 9,509.28 -203.00 (-2.09%)
S&P 500 1,029.84 -27.24 (-2.58%)
Nasdaq 2,057.48 -64.94 (-3.06%)

Back in the 1950s, Roger Penske not only raced cars, but he also sold them. And, when he retired in 1965, he focused on his business interests, creating an empire. Now, there is Penske Auto (NYSE: PAG), which operates a chain of auto dealers, a truck leasing operation, and a high-performance car operation.

Well, this week the empire got even bigger; that is, Penske agreed to purchase the Saturn unit from General Motors. Terms of the deal were not disclosed.
