This ETF Is Feasting on SpaceX Stock. It's Also a Play on a Possible Tesla Acquisition.

The Baron First Principles ETF (RONB) has emerged as the leading ETF proxy for SpaceX stock, holding a 31.2% allocation just five days after SpaceX's IPO. The fund also holds Tesla as its second-largest position at nearly 12%, making it a concentrated bet on two Elon Musk companies. Founder Ron Baron has been a long-time investor in both companies and is bullish on SpaceX reaching a $20 trillion valuation within a decade. The ETF charges a 1% annual fee and may appeal to risk-tolerant investors seeking exposure to Musk's ventures.
