Our read on CPRO
ASmall-cap exposure without small-cap drawdowns: CPRO tracks the Russell 2000 and aims to shield 100% of capital across each one-year outcome period, trading away upside above a preset cap.
The ETF seeks to provide Russell 2000 exposure with defined upside participation while protecting 100% of capital from losses over the one-year outcome period.
Why people hold it
- Full armor, not a partial buffer: the design targets 100% downside protection over the one-year outcome period, versus the 9% or 15% slices typical of buffer funds.calamos.com
- At 0.69%, it undercuts the typical fee in its downside-protection peer group, including RFLR, the other fund built on the same Russell 2000 floor idea.
- Calamos brought the first 100% one-year protected Russell 2000 ETF to market, and CPRO is the October vintage; CPRY and CPRJ start their years in January and July.calamos.comprnewswire.com
- A plain 1940 Act ETF you trade in a brokerage account, not a structured note bought through a bank.calamos.com
Worth knowing
- The cap is the price of the floor. It resets each October, applies before the 0.69% fee, and a big small-cap year gets trimmed to that ceiling.calamos.com
- The math is built around holding the full October-to-September period. Buy mid-period and you inherit whatever cap and protection level remain.calamos.com
- Small and thinly traded, so use limit orders. The options structure also isn't designed to produce an income stream.
