Calamos Tax-Aware Collateral ETF is an actively managed fund designed as a tax-efficient alternative to Treasury bills and ultra-short duration bonds. The strategy seeks stable growth and yields above risk-free rates by investing in FLEX options box spreads, primarily on the SPDR S&P 500 ETF (SPY). It serves as a duration-neutral cash management tool and a high-quality collateral engine for investors pairing it with structured protection or other overlay strategies.
