Roundhill Box Spread 

XBOX uses a market-neutral options strategy built around box spreads, which combines synthetic long and short positions to create a defined payoff at expiration. These positions are constructed using exchange-listed options, typically on broad equity ETFs or indices, and are designed to lock in a fixed return based on the difference between strike prices. The portfolio holds multiple box spreads with maturities generally ranging from one to six months, with positions added, rolled, or replaced over time to reflect changing market conditions and implied rates. Because the long and short components offset each other, returns are largely independent of equity market direction and instead reflect prevailing short-term financing conditions and pricing in options markets. Collateral may be held in cash, cash equivalents, or US government securities, and the strategy is managed with the intention of avoiding regular income distributions.
