Stocks for small banks rose because investors believe those companies will benefit from being able to charge higher rates when they make loansBut homebuilder Lennar was the second-biggest decliner on the S&P 500, falling $1.42, or 4 percent, to $33.93. Investors worried that higher interest rates will make mortgages more expensive and tamp down on demand, although rates will still be low by historical standards. The price of oil rose $1.98, or 2 percent, to $103.22 a barrel in New York. That could signal investors are optimistic about U.S. manufacturing and the broader economy â¿¿ or it could mean they're unnerved by political unrest in Egypt.

The dollar rose, which likely means that investors were feeling confident about the U.S. economy. As for the U.S. jobs report, investors said it represented an economy on the mend. The 195,000 additional jobs in June handily beat expectations for an increase of 165,000. The government also said that the economy added 70,000 more jobs in April and May combined than previously thought.
