CPSLACalamos Laddered S&P 500 Structured Alt Protection ETF

CPSNBCalamos S&P 500 Structured Alt Protection ETF – November

In short

CPSL No data

CPSN A one-year airbag strapped to the S&P 500: CPSN aims to shield 100% of index price losses over its outcome period, before fees, in exchange for a hard cap on the upside that resets every November.

Stated mandate

CPSL No data

CPSN The fund seeks positive S&P 500 price-return exposure up to a defined cap while protecting against 100% of losses over its one-year outcome period, before fees and expenses.

Why people hold it

CPSL No data

  • CPSN Aims to protect against 100% of S&P 500 price losses over its one-year outcome period, before fees and expenses. Not a partial buffer that can be used up.calamos.com
  • 0.69% expense ratio, level with the median for S&P 500 full-protection funds, and it sits in the upper half of that peer group overall.
  • Calamos runs the same structure across the calendar (CPSJ, CPSM, CPSP, CPSA), so a November start is one entry point among many rather than a single make-or-break date.
  • Every November a fresh one-year period opens with a newly set cap, so the terms re-price to current market conditions instead of locking in indefinitely.

Worth knowing

CPSL No data

  • CPSN The upside is capped, and the cap is reset each period from options pricing. Exposure is to S&P 500 price return, so index dividends are not part of the deal.calamos.com
  • The protection is stated before fees and expenses and applies to a full period held start to finish. Buy mid-period and your own cap and protection look different.calamos.com
  • A small, thinly traded fund inside a crowded family of monthly siblings. Spreads can be wider than at the household-name outcome ETFs, so limit orders matter.
