Neos Enhanced Income Cash Alternative ETF (CSHI) is an actively managed exchange-traded fund that seeks to generate enhanced monthly income through a portfolio of 1-3 month U.S. Treasury Bills combined with a data-driven options overlay strategy involving the sale and purchase of S&P 500 Index put options classified as Section 1256 contracts for tax efficiency. The fund, issued by NEOS Investments and listed on the NYSE Arca, targets investors seeking a tax-efficient cash alternative with higher yields than traditional T-Bills, lower correlation to equity markets, and monthly distributions estimated at 56% return of capital as of late 2025; it benchmarks against the Bloomberg U.S. 1-3 Month T-Bill Index while offering a gross expense ratio of 0.38%, net assets exceeding $765 million, and a distribution rate of approximately 4.94% as of December 2025.
