U.S. stock futures changed slightly on Sunday night after the Dow Jones Industrial Average and the S&P 500 had their best weekly gain streak of 2024.

Futures for the Dow Jones Industrial Average rose by 36 points, or 0.08%. Futures for the S&P 500 and Nasdaq 100 increased by 0.09% and 0.08%, respectively.

These movements come after the S&P 500 and the 30-stock Dow Jones recorded their highest levels ever on Friday, bolstering their sixth consecutive weekly gain, which is the best for both indexes this year.

The S&P 500 finished the week up by 0.85%, while the Dow Jones closed up by 0.96%. The Nasdaq Composite rose by 0.80%.

The ability of stocks to maintain gains may largely depend on whether companies can exceed expectations in the earnings season, which is set to pick up this week. Nearly a fifth of the companies listed on the S&P 500 are expected to report by Friday.

Among the 14% of S&P 500 companies that have already announced their third-quarter results, 79% exceeded expectations, according to John Butters from FactSet. However, he noted that the magnitude of those beats has been more subdued.

The recent winning streak has left investors optimistic that stocks still have more work ahead. However, they are aware that stretched valuations, ahead of the U.S. presidential election and amid ongoing geopolitical risks, will also mean more volatility.

In this context, CFRA Research's chief investment strategist Sam Stovall said, "If we don't really get some kind of confirmation that the market deserves this high price, we may end up seeing gains digested fairly soon."

On another front, in the economic arena, key indicators for September are set to be released on Monday.
