Our read on CPNM

ETF.net Research

BMost buffer funds absorb the first 10% or 15% of a drop. This one is built to shield the entire Nasdaq-100 downside across its one-year period, and hands the upside back to you only up to a cap set at each reset.

Stated mandate

The fund seeks exposure to the Nasdaq-100 with upside participation limited by a cap, while providing 100% capital protection over the one-year outcome period.

Why people hold it

  1. 01Full protection, not a partial buffer: the structure targets 100% downside coverage on the Nasdaq-100 over each one-year outcome period.calamos.com
  2. 02At 0.69%, it undercuts the typical Nasdaq-100 buffer fund on fees and matches its June and September siblings (CPNJ, CPNS) to the basis point.
  3. 03One of three Calamos start months (March, June, September), so entry dates can be staggered instead of tied to a single reset calendar.
  4. 04Sits in the upper half of its Nasdaq-100 protection and buffer peer group, with cost and downside control the sturdier parts of the profile.

Worth knowing

  1. 01The cap is what pays for the protection. It is set fresh at each period start, and a hot Nasdaq year can finish well above it.
  2. 02The outcome runs period to period. Buy mid-period or sell early and you get whatever the options are worth that day, not the stated terms.
  3. 03Small and lightly traded next to the category's giants, and it launched in 2025, so the history is short and spreads can run wider.
