Our read on CPSF
CA full floor, not a buffer: it aims to match the S&P 500's price return up to a set cap while absorbing 100% of losses over its one-year outcome period, before fees. February is one rung of Calamos's monthly protection ladder.
The fund is designed to match the positive price return of the S&P 500 up to a defined cap while protecting against 100% of losses over the one-year outcome period, before fees and expenses.
Why people hold it
- The floor is the product: 100% of S&P 500 price losses absorbed across the one-year outcome period, before fees and expenses. The whole drawdown, not a 10% or 20% slice of it.calamos.com
- Charges 0.69% a year, right at the median for S&P 500 full-protection funds. No surcharge for the structure.
- One rung of a monthly series (CPSP in April, CPSM in May, CPSJ in July, CPST in September, all at 0.69%), so entry dates can be staggered instead of staked on a single reset.
- A plain 1940 Act ETF that references SPY, so the protection sits in an options package inside a fund rather than in a bank's promise on a structured note.calamos.com
Worth knowing
- The price of a full floor is a ceiling. Upside stops at a cap reset each period by options pricing, and the fund follows price return, so index dividends stay behind.
- The math assumes buying at the reset and holding to the end. Step in mid-period and both the effective cap and the protection left differ from the headline terms.
- Launched in 2025, no distributions (the return lives in the share price), and not among the category's heavily traded names, so the spread can matter at the ticket.
