Our read on each fund

ETF.net Research

ARKEFARK DIET Q3 Buffer ETF

CPNSACalamos Nasdaq-100 Structured Alt Protection ETF – September

In short

ARKE No data

CPNS Armor, not a cushion. CPNS uses options on the Nasdaq-100 to target 100% protection from losses over a one-year outcome period, before fees, and pays for that shield with a hard cap on the upside that resets every September.

Stated mandate

ARKE No data

CPNS Seeks to provide positive price-return participation in the Nasdaq-100 up to a predetermined cap while protecting 100% of losses over the one-year outcome period, before fees and expenses.

Why people hold it

ARKE No data

  • CPNS The whole design in one line: participate in Nasdaq-100 price gains up to a preset cap while aiming to protect 100% of losses over the one-year outcome period, before fees and expenses.calamos.com
  • Fee is 0.69% a year, below the median for Nasdaq-100 buffer and protection funds. In a strategy where the option budget sets your cap, a lower fee leaves more to spend on upside.
  • September is one vintage in a quarterly series (CPNM March, CPNJ June), so investors can stagger entry points instead of betting everything on one reset date.
  • Among the dozen-odd Nasdaq-100 protection and buffer funds we track, this one sits in the upper tier on cost and risk build quality.

Worth knowing

ARKE No data

  • CPNS The cap is the price of the armor. It is set at the start of each outcome period and changes with market conditions, and the stated outcomes assume holding from one reset date to the next.
  • It tracks Nasdaq-100 price return, so index dividends are not part of the deal, and the fund has not been a distribution payer.
  • A small, thinly traded fund since its 2024 launch, so bid-ask spreads and order size deserve attention at the point of trade.
