Wall Street's Newest Stock-Split Stock -- an $85 Billion Colossus That's Been Unstoppable for 3 Years -- Has Arrived

Investors are showing interest in companies undergoing stock splits, with Fastenal and O'Reilly Automotive recently completing splits and Interactive Brokers Group (IBKR) beginning trading at its split-adjusted price on June 18. IBKR's 4-for-1 split comes after a 271% rally over three years, driven by increased investor confidence and the company's investments in technology and automation, leading to growth in customer accounts, equity, margin loans, and daily active revenue trades; however, the stock market's high valuation, as indicated by the S&P 500's Shiller P/E Ratio, poses a potential short-term threat.

Analysis

Investor attention is increasingly drawn to companies executing forward stock splits, a trend exemplified by recent activities from non-tech influential businesses. Fastenal (FAST) completed a 2-for-1 split on May 21, its ninth in 37 years, reflecting a corporate culture intertwined with its significant long-term share appreciation of over 200,000% since its 1987 IPO. Fastenal's cyclical operating model benefits from traditionally short recessions (average 10 months post-WWII) and longer economic expansions (average 5 years), supporting demand for its industrial supplies and innovative managed inventory solutions. O'Reilly Automotive (ORLY) executed a 15-for-1 split on June 9, supported by a robust distribution network of 31 centers and nearly 400 hub stores ensuring rapid parts delivery, and a substantial share repurchase program that has retired over 59% of outstanding shares since 2011, positively impacting its earnings per share. Interactive Brokers Group (IBKR), with an $85 billion market capitalization, commenced trading on a split-adjusted basis (4-for-1) on June 18, following a 271% stock rally over the preceding three years. IBKR's growth is fueled by positive investor sentiment, which historically benefits from longer bull market cycles, and significant investments in technology and automation. These investments have enabled competitive pricing and driven strong Key Performance Indicator (KPI) growth as of March 31 year-over-year, including a 32% rise in customer accounts to 3.62 million, a 23% increase in platform equity to $573.5 billion, a 24% jump in margin loans to $63.7 billion, and a 50% surge in daily active revenue trades to 3.52 million. A potential near-term headwind for IBKR is the historically high S&P 500 Shiller P/E ratio, which neared 39 in December, historically a precursor to market declines.

Key Decisions for Investors

• Investors should observe that forward stock splits by companies like Fastenal, O'Reilly Automotive, and Interactive Brokers often signal strong underlying business performance and innovation, meriting deeper fundamental analysis beyond the nominal share price adjustment.
• Interactive Brokers presents a compelling growth narrative given its significant KPI improvements, such as a 32% YoY increase in customer accounts and a 50% rise in daily active revenue trades, and its technological advantages, though potential market-wide valuation risks, indicated by the high Shiller P/E ratio, warrant consideration for short-term volatility.
• Consider Fastenal for its established linkage to U.S. economic cycles and proven long-term growth, and O'Reilly Automotive for its effective capital return strategy through substantial share buybacks and resilient business model underscored by its extensive distribution network.
