Investors watch job numbers and the Fed after pushing Dow to record high this week.
America's stock market has been buoyant, even though credit markets are still creaky and an outright recession grips the housing market, a sector that often gives early warning of wider economic slumps.
What has fueled a run-up of stock prices that set a new record high for one key index this week?
The answer, to borrow a phrase from the cold war, may be "containment."
Many investors have gauged that the overall economy is mostly insulated from housing and credit troubles – thanks in part to the Federal Reserve's willingness to provide a monetary nudge as needed.
Similarly, investment strategists are confident that even if the US hits a slow patch, a strong world economy will bolster earnings for the biggest US companies. The world is more insulated from a slowdown in the US than it used to be.
"We haven't seen the end of the impact of the credit crunch," and the housing downturn "has further to go," says David Kudla, chief executive officer and strategist at Mainstay Capital Management in Grand Blanc, Mich. But "we don't expect that it has the ripple effect ...such that it causes a recession or a significant market decline."
If this benign scenario holds true, the stock market could provide some comfort to Main Street as well as Wall Street. It would imply healthy profits at corporations, which could inspire more job-creating investments. And, while not every homeowner owns stocks, it could also help consumer confidence.
At the very least, a resilient stock market would mean that capital gains on stocks would help offset any continuing drop in home prices on America's collective household balance sheet.
In general, the stock market can be a leading indicator of where the economy is headed – since investors are pricing shares based on expected future earnings.
