News Summary: Stocks march back into record territory, boosted by small business sentiment

THE BACKBONE: An improvement in small business sentiment gave investors a reason to push stocks back into record territory Tuesday. The Russell 2000, an index of small company stocks, climbed 1.3 percent. The index is up 16.1 percent this year and is outperforming the Standard & Poor's 500.

GOLDILOCKS REDUX: The prospect of more stimulus from the Federal Reserve is also underpinning the rally. The economy is growing fast enough to help corporations boost profits but not so fast that the U.S. central bank will to stop its $85 billion-a-month bond buying program.

HITTING THE BRAKES: A surge in Tesla's stock came to a halt Tuesday. The electric carmaker's stock fell $4.56, or 5.2 percent, to $83.24 after climbing as high as $97.12 during trading. The stock has surged 49 percent since May 8, when Tesla reported its first quarterly profit.
