Our read on CPSJ

ETF.net Research

COne rung on Calamos' monthly ladder of S&P 500 funds built to shield 100% of index price losses across a one-year outcome period, in exchange for a cap set each July. Full armor, ceiling included.

Stated mandate

The fund seeks to provide the positive price return of the S&P 500 up to a defined cap while protecting against 100% of losses during a one-year outcome period.

Why people hold it

  1. 01The trade is spelled out up front: protection against 100% of S&P 500 price losses over the one-year outcome period, with upside capped at a level fixed when the period starts.calamos.com
  2. 02At 0.69%, the fee sits at the median of the full-protection group and under JAJL's 0.79% on the same index.
  3. 03Calamos staggers these by start month (April, May, July, August, September and more), so a fresh outcome period is never a year away.
  4. 04Rates as one of the stronger implementations in its peer group of 100% protected S&P 500 funds.

Worth knowing

  1. 01Upside follows the S&P 500 price only, so dividends sit outside the deal, and gains stop at the cap for that period.
  2. 02The protection is a full-period contract. Buy mid-period or sell before it ends and your effective cap and downside cushion differ from the stated terms.calamos.com
  3. 03A smaller, thinly traded member of the family, so spreads can run wider than the busiest protection funds. It also isn't structured as an income payer.
