The first half of the year has flown by and stocks certainly have a lot to show for it.

The S&P 500 (INDEX: .SPX) and the Dow Jones industrial average (Dow Jones Global Indexes: .DJI) notched their biggest first-half gains since 2013. The tech-heavy Nasdaq composite (NASDAQ: .IXIC), meanwhile, left them in the dust, surging 14.2 percent to post its best start to a year since 2009.

Technology stocks were a big driver for the broader market during the first six months of 2017, outperforming other sectors. But Wall Street's favorite stocks have hit a snag recently.

To boot, investors will only have three full trading days to digest a slew of economic data. The stock market closes at 1 p.m. on Monday and will not open Tuesday because of the Fourth of July holiday.

As the first week of the second half of 2017 begins, here's what investors need to watch: Tech, banks and key data about the jobs market and auto sales.

Fall in tech stocks keeps Wall Street on edge

Tech stocks were Wall Street's darlings in the first half, with the sector rising 16.2 percent. Giants in the space like, Facebook (NASDAQ: FB), Apple (NASDAQ: AAPL), Google-parent Alphabet (NASDAQ: GOOGL) and Netflix have all spiked at least 17 percent in 2017.

That said, tech hit a slump in June, dropping nearly 3 percent during the month as high valuations led investors to pare down their tech positions.

"I think investors will be a bit on edge now that tech has shown signs of cracking, but this is not surprising given the run they've had," said Mike Baele, managing director at U.S. Bank Private Client Reserve.

Added losses in tech are likely to push the stock market lower, so keep an eye on the sector. Tech's slide, however, has led to money flowing into more neglected areas of the market, such as bank stocks.

Bank stocks back in vogue

Banks came out of their funk in June, with the SPDR S&P Bank exchange-traded fund (KBE) — which tracks large-bank stocks — advancing 5.8 percent.

Big-bank stocks got a boost last week after the Federal Reserve approved share buyback programs and higher dividend yields for the big banks.

The central bank did not object to any of the buybacks or dividend hikes from the 34 banks it reviewed during the second phase of its annual stress test. This was the first time in the seven-year history of the tests implemented in the wake of the financial crisis that all banks have passed.

The Fed's blessing, coupled with a recent rise in global interest rates, have some on Wall Street licking their chops to plow more money into bank stocks.
