Caution Ahead: BPTRX and BPTIX's Heavy SpaceX Bet Raises the Stakes
Read MoreHide Full Article
Investors looking at the Baron Partners funds, through retail fund Baron Partners Retail (BPTRX - Free Report) and institutional funds Baron Partners Institutional (BPTIX - Free Report) , should approach the funds with caution. Although the strategy has delivered exceptional long-term returns, its concentrated portfolio has produced substantial volatility in 2026. Zacks currently lists both with a Mutual Fund Rank of #5 (Strong Sell). To see how these funds performed compared to their category, and Top-Ranked Zacks Mutual Funds, please click here.
Recent performance illustrates the risk. BPTRX and BPTIX had posted one-year returns of 24.94% and 25.25%, respectively, through July 31, 2026, but the funds have struggled more recently, with their performance pressured by sharp declines in SpaceX and Tesla. Year to date till July 31, BPTRX and BPTIX have declined 5.4% and 5.2%, respectively.
The biggest reason for the volatility is SpaceX. Baron Partners has accumulated SpaceX shares since 2017, giving investors exposure to the private company well before its public-market debut. Till June 30, SpaceX comprised of 35% of both the funds’ holdings. This exposure has become a double-edged sword. A recent Barron’s report noted that SpaceX and Tesla together accounted for roughly 47% of Baron Partners, meaning major moves in either company can have an outsized impact on the mutual fund. SpaceX shares subsequently suffered a steep decline from their June peak, highlighting the concentration risk.
Still, Ron Baron remains extremely optimistic about SpaceX’s long-term prospects. He describes the company as a potential “lifetime investment opportunity” and believes its businesses spanning Starlink, space transportation and other technologies could create enormous value over the coming decade. Baron has even projected SpaceX to grow between $10 trillion to $30 trillion over 10-15 years following the IPO.
The opportunity is compelling, but so is the risk. BPTRX and BPTIX offer unusually high SpaceX exposure, but investors should be prepared for significant swings if Musk-related companies disappoint.
