CPSM is a highly unique new ETF that aims to track the returns of the S&P 500 index while offering a 100% downside current protection level over its outcome period.

We've previously covered buffer ETFs in part 3 of our series on options strategies in ETFs, explaining the typical setup where these funds mitigate a certain percentage of losses (usually between 10-20%) over a defined outcome period—often a calendar year starting in a specific month.
They manage this at the cost of capping upside potential and excluding dividends, usually through a multi-leg options strategy. These ETFs aren't a free lunch – rather, they're a way to redefine the risk and return trade-off in your portfolio.
Now, Calamos, a renowned alternative investment manager with substantial derivatives expertise, has introduced a new twist with its Calamos S&P 500 Structured Alt Protection ETF – May
But, for those of you who prefer a written format, here's a detailed look at how CPSM works and my thoughts on its potential impact. Also, keep your eye out as Calamos will be launching similar products with exposure to the Nasdaq-100 and Russell 2000 in June and July, respectively.

As with most buffer ETFs, understanding the mechanics of the CPSM is straightforward when we break it down into three key components:
Currently, as of May 6, 2024, the CPSM shows:
These figures are continuously updated and can be tracked on the ETF's webpage to see how much of the upside cap, protection level, and time left in the outcome period are available at any given point.
It's important to note that both ETFs can trade above and below the starting NAV during the outcome period. While they will maintain a floor against loss at the starting net asset value (NAV) over the full period, an investor can lose principal should they invest in the fund after the outcome period has begun if they have appreciated.
Should these ETF's NAV then fall, an investor could lose a portion of their investment over the remainder of the annual outcome period.
Conversely, if the ETF trades below its starting NAV, the upside cap will effectively expand above the final cap announced at the launch of the fund. If shares are held through the remainder of the outcome period, an investor can expect the NAV to return to its starting level. Such instances can provide attractive entry points.
While buffer ETFs might seem like a straightforward win due to their 'defined outcome' feature, they're essentially an insurance policy. The cost of this insurance is embedded in the options pricing, which aims to provide more predictable outcomes.
These ETFs are particularly well-suited for investors who are risk-averse and find market volatility unnerving. The guaranteed limit on losses can provide the emotional and financial security needed to remain invested during market downturns, which can be particularly beneficial when advised by a financial professional.
I also see significant value in considering CPSM as an alternative to traditional fixed-income investments, especially in light of the hefty losses sustained by aggregate bond and long-duration Treasury ETFs during the tumultuous rate hikes and high inflation of 2022.
However, it's important to temper expectations with the 9.81% upside cap. While this might seem attractive, remember that historically, the S&P 500 has often delivered returns well above this threshold. In a bull market, an investment in CPSM could significantly lag due to this cap, which is the trade-off for downside protection.
Moreover, the exclusion of dividends in the calculation of the return is a critical consideration. Historically, reinvested dividends have accounted for about a third of the total returns of the S&P 500. Missing out on these can impact the compounding benefits significantly over time.
Despite these considerations, CPSM has demonstrated strong market appeal. Since its launch on May 1, 2024, it has quickly attracted $108.9 million in assets under management—an impressive feat for a complex ETF with a 0.69% expense ratio.
