About CSTBX

Calamos Short-Term Bond Fund Class A is an actively managed mutual fund focused on generating a high level of current income while emphasizing preservation of principal. The fund invests predominantly in investment-grade fixed income with a portfolio duration of roughly three years or less, spanning U.S. government and agency obligations, corporate bonds, mortgage- and asset-backed securities, and other short-maturity instruments. It may also allocate a modest portion to below-investment-grade debt within defined limits, reflecting a multi-sector approach to income generation and risk management. The strategy targets lower interest rate sensitivity relative to intermediate- or long-duration bond funds, positioning it as a tool for liquidity needs and capital stability over shorter horizons. The fund distributes income monthly and has operated since 2018 under the Calamos investment platform. Key structural features include a front-end load share class and an expense ratio in line with short-term bond category norms. By concentrating on high-quality, short-duration credit across sectors, Calamos Short-Term Bond Fund Class A plays a role in fixed income allocations seeking steady income, dampened volatility, and diversification from equity market risk.
