Wall Street ends slightly higher in shortened session, Tesla jumps

Wall Street's main indexes ended with slim gains in a holiday-shortened session on Monday, helped by a surge in Tesla and strength in bank shares as the second half of the year kicked off on a subdued note.

Tesla shares jumped 6.9% as the electric vehicle maker said it delivered a record number of vehicles in the second quarter.

Shares of major banks gained after the companies raised dividends as they sailed through the Federal Reserve's annual health check. Wells Fargo shares rose 1.7%, Citigroup shares climbed 1.5%, while the S&P 500 banks index ended up 1.5%.

Trading volumes were lighter than average as the stock market closed at 1 p.m. ET ahead of the July 4th Independence Day holiday on Tuesday.

The Dow Jones Industrial Average rose 10.87 points, or 0.03%, to 34,418.47; the S&P 500 gained 5.21 points, or 0.12%, at 4,455.59; and the Nasdaq Composite added 28.85 points, or 0.21%, at 13,816.77.

While nine of the 11 S&P 500 sectors rose, healthcare fell the most, dropping 0.8%, while the heavyweight technology sector fell 0.3%.
