Baron Capital backs visionary leaders in RONB ETF
Baron Capital uses leadership as a primary selection metric for the actively managed Baron First Principles ETF (RONB), taking large positions after months or years of research.
Baron Capital uses the quality of founders and executives as a core selection metric for the Baron First Principles ETF (RONB), and takes sizable, concentrated positions only after extended research. The firm says its approach emphasizes long-term business compounding and leaders who can sustain growth over time.
The firm applies a firm-wide, fundamental bottom-up research process that seeks to filter out short-term market noise. Analysts look for companies with durable competitive advantages and management teams aligned with shareholder interests and willing to reinvent the business when needed. The ETF’s active management allows the portfolio team to concentrate holdings where research identifies sustained, differentiated opportunities.
Baron Capital conducts months or years of study before initiating a position and continues research after investing. “First, we spend months or even years researching companies before initiating positions and continue that deep research throughout the life of every investment,” portfolio manager David Baron said in a Q&A. He added the team focuses on leaders who view their companies through a long-term lens and can execute repeated waves of growth.
The ETF’s mandate prioritizes investing alongside management teams that meet the firm’s criteria rather than assembling widely held, short-term popular stocks. When a company meets Baron’s standards for leadership and business model durability, the firm is prepared to allocate substantially and increase weightings as conviction builds.
Active management gives Baron the flexibility to adjust position sizes and raise exposure when ongoing research continues to support the investment thesis. The firm describes its holdings as long-term partnerships with innovators that possess durable market positions and leadership the team expects can support extended growth.
Baron Capital links RONB to its broader “first principles” analysis, which examines how a company can grow and defend advantages beyond its financial statements. The ETF is positioned for investors seeking a concentrated, research-driven portfolio rather than a rules-based index.
