US stock futures showed minimal movement on Tuesday, with the three primary indices remaining relatively stable as investors exercised caution in light of an impending government shutdown that could potentially delay the release of crucial labor data later in the week. The government risks a shutdown if Democrats and Republicans do not reach an agreement today, jeopardizing the scheduled release of the payrolls report on Friday. Additionally, investors were anticipating the JOLTS job openings data expected later in the day. Remarkably, for September, the S&P 500 has increased by more than 3%, positioning it for its strongest September performance in 15 years. Concurrently, the Dow Jones has risen by 1.7%, while the Nasdaq has seen a significant surge of 5.3%. Examining the third quarter, the S&P 500 experienced a 7.4% gain, the Dow advanced by 1.7%, and the Nasdaq impressively climbed by nearly 11%.
