U.S. stock futures opened lower on Sunday night, signaling a potential continuation of the volatility that plagued Wall Street during the previous week. Dow Jones Industrial Average futures fell by 221 points or 0.6%, while S&P 500 futures and Nasdaq-100 futures dipped 0.9% and 1.2% respectively.

The stock market endured a challenging week, with the Nasdaq Composite slipping into correction territory. The tech-heavy index experienced a decline of over 10% from its record high set just a month ago. Similarly, the S&P 500 suffered its third straight week of losses, ending the week down 2%, while the Dow Jones Industrial Average, which had been performing well, snapped a four-week winning streak, falling 2%.

Adding to the downward pressure, Treasury yields also tumbled, with the benchmark 10-year note displaying a yield of 3.79% on Friday, down from the previous week's 4.20%. Investor concerns were further amplified by a disappointing jobs report, leading to fears that the Federal Reserve's decision to keep interest rates unchanged may have been a mistake and that the economy is potentially heading towards a recession.

Despite the recent pullback in stocks, some market analysts remain optimistic about the overall trend. Keith Lerner, co-chief investment officer at Truist Wealth, believes that the bull market is still intact but expects a choppy period before a recovery. Lerner stated, "I think we're in that corrective period, but we still think the bull market trend is intact. It's just going to take a little bit to get through this kind of choppier period."

Investors will closely watch for any further developments as the S&P 500 currently sits 5.7% below its all-time high, while the Dow Jones Industrial Average is down by 3.9%. Additionally, Apple's stock performance will be a key focus on Monday following news that Warren Buffett's Berkshire Hathaway has sold nearly half of its stake in the iPhone maker.

Economic data due out on Monday includes the July ISM Services PMI, which measures the performance of U.S. services companies. Analysts anticipate a rise to 50.9, up from 48.8 previously. This data could provide insight into how the Federal Reserve may approach interest rates in the coming week. Furthermore, the market will pay attention to San Francisco Fed President Mary Daly's speech at the Hawaii Executive Collaborative after the market closes on Monday.

As the new week begins, investors await further market movements and economic indicators to determine whether the downward trend will persist or if a recovery is imminent.
