SPDR, the ETF giant behind the SPY, has filed for a new fund that aims to bring a classic institutional allocation to retail investors. The UC Investments 90/10 Endowment Strategy Index ETF would track an index that splits assets 90% in equities and 10% in bonds — a structure long favored by university endowments and pension funds.
What the 90/10 split means
The 90/10 strategy is straightforward: put the bulk of the portfolio in stocks for growth, and park the rest in fixed income to cushion downturns. Endowments like Yale and Harvard have used similar mixes for decades, betting that equities will outpace bonds over the long haul while the bond slice provides a shock absorber during market slides.
SPDR hasn't disclosed the specific index the ETF will track, nor the expense ratio. The filing, submitted to the SEC, only sketches the fund's objective: to deliver the risk-return profile of that 90/10 split. The 10% bond component would likely include Treasuries or investment-grade corporate debt, but the exact holdings will depend on the index methodology.
The filing is a sign that asset managers see demand for simple, rules-based strategies that mimic institutional playbooks. Individual investors have been piling into target-date funds and balanced ETFs, but a dedicated 90/10 product is rarer. SPDR already offers a range of sector and factor ETFs, but this would be its first endowment-style fund.
UC Investments — the asset management arm of the University of California — is the name on the strategy. The UC system oversees roughly $170 billion across its pension, endowment, and working capital pools. Partnering with a name that big gives the ETF instant credibility, even if the underlying index is a straightforward blend.
What’s next
The SEC will review the filing over the coming months. If approved, the ETF could launch later this year. SPDR hasn't announced a ticker or a target date. Until then, investors who want a 90/10 mix will have to build it themselves — or wait for this fund to hit the market.
