Ultra-short-term Treasury bills tend to be less sensitive to interest rate fluctuations compared to longer-duration bonds, making SPTU a potentially attractive option during periods of rising rates. The ETF competes with other ultra-short bond ETFs, but its low expense ratio and focus on Treasury bills may appeal to cost-conscious investors seeking a safe haven asset. Demand for short-term fixed income is often driven by expectations regarding Federal Reserve policy and the overall economic outlook. Past performance does not guarantee future results. ## Frequently Asked Questions ### What is SPTU and what does it track?
