 I'm Peter Schachnow, CNBC. Wall Street is hoping for a fresh start this week, following the worst week for the S&P 500 and Nasdaq in three months. Much of that came from a tech-related sell-off as investors took profits from this year's significant gains. There is plenty of underlying optimism despite last week's slide. Investors are starting to buy stocks outside the so-called Magnificent Seven, most notably the small-cap stocks, and optimism is growing about a Fed interest rate cut in September.
