Post-SpaceX IPO, Investors Pour $83B Into U.S. Equities

The SpaceX IPO brought with it a fair amount of hype for thematic ETFs, already soaring this year on ongoing semiconductor demand. While basic, passive S&P 500 exposure via the iShares Core S&P 500 ETF (IVV) drew in the most aggregate flows last week, the $8.3 billion and $7.4 billion into the Technology Select Sector SPDR Fund (XLK) and the VanEck Semiconductor ETF (SMH) respectively underscore the ongoing popularity of all things tech for investors. 

International equities also pulled in a respectable $21.6 billion, followed by U.S. fixed income and international fixed income. For now at least, U.S. equity enthusiasm simply dominates the market. Whether that continues this summer remains to be seen. Of particular note, SpaceX enters into passive indexes as early as this week. 

On the redemptions side, $1.5 billion moved out of the Baron First Principles ETF (RONB), and the Tema Space Innovators ETF (NASA) experienced net outflows of nearly $690 million. The leveraged ETF category was the only one to experience net negative flows last week, and interest in currencies and commodities remained muted on ongoing geopolitical tensions and uncertainty.
