U.S. stock markets were closed yesterday to observe the Fourth of July holiday, but when they opened this morning, traders were in a buying mood. The addition of 195,000 jobs to the economy in June won't wow anyone, but it was better than expected and shows that the labor market is slowly growing. Investors cheered the news, and the Dow Jones Industrial Average (^DJI 0.57%) is up 0.72% today, while the S&P 500 (^GSPC 1.14%) has gained 0.69%.  

Banking stocks are the biggest beneficiaries today, because this data will add to speculation that the Federal Reserve will slow its $85 billion-per-month bond-buying program, taking away the economy's crutch. The Fed's program has aimed to keep long-term interest rates low, and they will likely continue to rise now that the economy appears to be strong. There's no indication that short-term rates will rise, though, and that means banks can borrow at low short-term rates while borrowing at higher long-term rates, boosting profits.

JPMorgan Chase (JPM 0.59%) is up 1.9% today as investors speculate that interest rate spreads will rise and defaults will fall for the giant bank. But American Express (AXP -0.29%) is also up 2% because a stronger economy means fewer defaults on its credit cards, and the higher long-term interest rates could help boost profits as well. In short, it's good to be a bank investor today.

The other big mover is oil, which has jumped nearly $2 to pass $103 for the first time since early last year. A stronger economy should mean more demand for oil, which is good news for oil producers because demand has actually been dropping since 2005 in the U.S.

Chevron (CVX 0.04%) is the big beneficiary on the Dow today, climbing 0.9%. The company doesn't rely on the price of oil to make a profit, but a higher price can make exploration more lucrative.
