CPSRCCalamos S&P 500 Structured Alt Protection ETF – March

MAXJAiShares Large Cap Max Buffer Jun ETF

In short

CPSR Calamos's March gate into fully protected S&P 500 exposure: a one-year outcome period built to absorb every index loss, before fees, in exchange for a firm ceiling on the upside.

MAXJ No data

Stated mandate

CPSR The fund seeks to provide the positive price return of the S&P 500 up to a defined cap while protecting against all losses during a one-year outcome period, before fees and expenses.

MAXJ No data

Why people hold it

  • CPSR Protection is the whole point. Each one-year outcome period targets none of the S&P 500's losses, before fees and expenses, rather than a 10% or 15% buffer.calamos.com
  • Part of a series with entry points every month, so a fresh outcome period opens regularly instead of once a year.calamos.com
  • The 0.69% fee sits at the median of its fully protected peer group and matches siblings like CPSM and CPSJ, so month of entry, not cost, is the differentiator.

MAXJ No data

Worth knowing

  • CPSR The upside cap is set at each period's start and resets. Buy mid-period and your personal cap and protection level differ from the headline terms.calamos.com
  • Protection is stated before fees and expenses, so the 0.69% expense ratio comes out of whatever the structure delivers.
  • Thinly traded with a small asset base, which can mean wider bid/ask spreads than the giants of the S&P 500 world.
