In the world of stock market trading, the S&P 500 and Nasdaq Composite indices continue their winning streak, with both indexes notching their longest positive runs in approximately two years. This news comes as U.S. stock futures remain relatively steady in Tuesday's night trading session, following a day of gains in the market.

The futures tied to the S&P 500 and Nasdaq 100 oscillated near the flat line, indicating a relatively stable outlook. Dow Jones Industrial Average futures also rose slightly, up 9 points or 0.02%. These positive movements contribute to the overall optimism surrounding the market.

Earlier in the day, the S&P 500 added 0.3% to secure its seventh consecutive positive session, while the Nasdaq Composite advanced by 0.9%, marking its eighth straight day of gains. This streak is a significant milestone for both indexes, as it marks the longest stretch of positive days since November 2021.

The Dow Jones Industrial Average, composed of 30 prominent stocks, also experienced a climb of nearly 0.2% on Tuesday, marking its seventh winning day. These gains can be attributed to the solid performance of the majority of S&P 500 companies throughout the earnings season.

An impressive 80% of S&P 500 companies have surpassed earnings estimates, indicating strong financial performance from many major players in the market. However, it is important to note that only 59% of these companies have managed to exceed revenue expectations. The gap between earnings and revenue performance is the widest it has been since the fourth quarter of 2015, according to LSEG.

Ken Mahoney, CEO of Mahoney Asset Management, expressed confidence in these ongoing equity gains. Mahoney believes that, coupled with limited central bank intervention, the market could be poised for continued success into 2024. He suggests that the economy is currently operating in a "Goldilocks environment," where conditions are neither too hot to prompt the Federal Reserve to raise interest rates, nor too cold to hinder growth.

Looking ahead, investors will keep an eye on several key earnings reports set to be released after Wednesday's closing bell. Companies like MGM Resorts, Walt Disney, and Take-Two Interactive are expected to reveal their financial results, which could potentially impact market movement.

In extended trading, some notable stocks experienced fluctuations. Robinhood, the trading platform app, saw its shares decline by more than 8% due to lower-than-anticipated third-quarter revenue of $467 million, compared to analysts' estimates of $478 million. E-commerce giant eBay also witnessed a drop of 6% as its third-quarter revenue of $2.5 billion aligned with analyst expectations. Toast, a provider of restaurant point-of-sale systems, saw its shares plummet by 17% in extended trading after reporting a third-quarter loss of 9 cents per share, falling short of the estimated 10 cents per share earnings.

As the night unfolds, stock futures remain relatively stagnant, with the Dow, S&P 500, and Nasdaq futures trading near the flat line. The market awaits September's wholesale inventories data, which could provide further insights into the economic landscape. Overall, the stability and continued positive performance of the major indexes suggest a sustained optimistic outlook in the stock market.
