These 3 Stock-Split Stocks Are Absolutely Crushing the Benchmark S&P 500 This Year

Investors have witnessed significant movements in the stock market this year, notably among companies engaging in forward stock splits. As we review the performance of three prominent companies that executed splits in 2025, it becomes clear how they are not only capturing investor interest but also substantially outperforming the benchmark S&P 500.

Stock splits are often viewed through a lens of investor psychology, where a lower nominal share price can make a company more accessible to retail investors. Companies that successfully execute forward splits typically exhibit robust operational performance, innovative strategies, and strong market demand.

As of mid-September 2025, we take a look at three noteworthy stock-split stocks: O’Reilly Automotive, Fastenal, and Interactive Brokers Group. Each has announced and executed forward splits with significant investor enthusiasm, resulting in year-to-date (YTD) performances well ahead of the S&P 500, which is up approximately 12%.

### O’Reilly Automotive: 36% YTD Growth

O’Reilly Automotive (ORLY) set the stage for stock-split excitement in 2025 by executing a 15-for-1 split in June. The company’s stock has surged 36% YTD, and the trajectory is even more impressive considering it has soared nearly 67,000% since its initial public offering in 1993.

One key driver for O’Reilly’s performance lies in the changing demographic of vehicles on the road. A recent report cited that the average age of vehicles has increased to 12.8 years, signaling a growing need for auto parts and maintenance. This trend benefits O’Reilly, as consumers are likely to turn to auto parts retailers for vehicle upkeep.

The company has also strengthened its distribution network, ensuring that products are easily accessible to both consumers and mechanics. With nearly 400 hub stores and 31 distribution centers, O’Reilly can deliver more than 153,000 stock keeping units efficiently.

Moreover, O’Reilly’s capital-return program is noteworthy. Since 2011, the firm has spent approximately $26.6 billion on share buybacks, effectively reducing its outstanding share count by nearly 60%. Buybacks often lead to enhanced earnings per share (EPS), adding another layer of appeal to investors.

### Fastenal: 32% YTD Growth

Another stock posting impressive results is Fastenal (FAST), a wholesale supplier of industrial and construction materials. With a YTD gain of 32%, Fastenal’s performance reflects its integral role in the economy. Known for its frequent stock splits, Fastenal executed a 2-for-1 split in May this year, marking its ninth split in 37 years.

The company’s resilience is tied to its business model that thrives during economic cycles. While downturns exist, Fastenal enjoys growth during expansions, which have historically lasted around five years. In the second quarter, over 73% of Fastenal’s net revenue originated from contract sales, indicating strong relationships with clients and ongoing demand for its products.

Innovation also plays a crucial role for Fastenal. By adopting managed inventory solutions, including wireless vending machines and inventory tracking bins, the company aids its clients in optimizing supply chain needs, further embedding its services in customer operations.

### Interactive Brokers Group: 44% YTD Growth

Leading the pack in stock-split performance is Interactive Brokers Group (IBKR), with an impressive 44% YTD growth. The firm executed a historic 4-for-1 stock split in June, marking its first such move since going public in 2007.

Interactive Brokers benefits greatly from positive market conditions and a growing trading atmosphere. As the S&P 500 reaches new heights, there’s a burgeoning interest among investors to engage in trading, resulting in higher platform activity. This demand is reflected in the company’s metrics, with a 32% increase in customer accounts and a 34% rise in customer equity during the June quarter.

The company’s commitment to technology and automation allows it to offer competitive benefits, such as higher interest rates on cash deposits and lower rates for margin borrowing. Innovative services resonate with customers, evidenced by a staggering 49% rise in daily active revenue trades.

### Conclusion

The 2025 forward stock splits by O’Reilly Automotive, Fastenal, and Interactive Brokers Group exemplify how strategic growth and strong fundamentals can lead to substantial market performance. Each company has skillfully adapted to economic trends, fostering investor confidence and resulting in YTD returns that significantly outpace the S&P 500.

As investment opportunities continue to evolve with trends such as stock splits and technological advancements, it is imperative for investors to remain informed and engaged with stocks that demonstrate resilience, operational efficiency, and forward-thinking strategies. The landscape of investing is ever-changing, but the success of these three companies serves as a reminder of the potential rewards for those who remain attuned to the market’s fluctuations.
