About this ETF
Calamos Structured Protected ETFs are engineered to allow investors to capture the positive price appreciation of the S&P 500, though this upside is limited by a predetermined cap. Simultaneously, these ETFs are designed to provide complete protection against any potential S&P 500 losses over a single one-year duration. It's important to note that this participation and protection are calculated prior to the deduction of fund fees and expenses.
