Calamos Antetokounmpo Global Sustainable Equities ETF (SROI)

The Calamos Antetokounmpo Global Sustainable Equities ETF tracks a strategy that combines two separate investment disciplines: it seeks companies with strong financial characteristics — profitable, well-managed, relatively inexpensive — that also meet environmental, social, and governance standards. The fund holds a diversified portfolio of dividend-paying stocks from developed and emerging markets worldwide, weighted toward companies that pass both financial and sustainability filters.

What the fund holds and how it selects them

SROI begins with a broad universe of global stocks, then applies a dual filter. The financial filter looks for companies with reasonable valuations, sustainable dividends, and evidence of strong management — traditional value and quality criteria. The ESG filter screens out companies involved in excluded sectors (tobacco, weapons, fossil-fuel generation, others) and evaluates the remainder on environmental performance (emissions, resource use, climate strategy), labour practices, board diversity, and other governance metrics. The result is a portfolio of typically 100 to 150 global equity holdings weighted toward developed markets (the United States, Europe, Japan) but with material exposure to emerging markets.

Because the strategy emphasizes dividend-paying stocks, SROI inherently skews toward mature, established companies in utilities, healthcare, financials, consumer staples, and real estate rather than faster-growing technology and communication sectors. This tilt shapes the fund’s behaviour and returns relative to a traditional global index.

How the fund works and who issues it

Calamos Advisors, a portfolio manager based in Chicago, oversees the fund’s strategy and holds the responsibility for security selection, portfolio construction, and rebalancing. The fund itself is a traditional ETF — a basket of stocks that trades throughout the day on an exchange like a single security, with shares purchased and sold by investors through brokers at market prices.

Being an ETF (not a mutual fund) gives SROI two advantages: lower expense ratios through the fund’s creation mechanism, and tax efficiency because the structure allows large holders to trade shares in-kind rather than forcing the fund to sell holdings and realize gains. The trade-off is that ETF investors face real-time bid-ask spreads; the fund can only ever hold exactly what the index calls for, so there is no active trading around valuations.

Risk and fit

Like all equity funds, SROI’s value moves with stock prices, so investors in it accept volatility and the possibility of loss in any year. But the fund carries specific risks tied to its choices.

The heavy weighting toward dividend-paying stocks means the fund tends to lag in years when growth stocks and technology companies dramatically outperform — a consistent pattern since the early 2020s. Holding global securities exposes the fund to currency fluctuation: when the US dollar strengthens, foreign dividend streams are worth fewer dollars to a US investor, regardless of what the stocks do. The ESG screen, while filtering for governance quality, can exclude promising companies at reasonable prices and may concentrate holdings in certain regions or sectors. And the emphasis on mature, profitable companies means SROI tends to capture less of the gains in emerging-market growth stories.

Dividend-focused strategies also carry reinvestment risk: in periods when interest rates are high, the cash from dividends is easy to redeploy at good returns; in low-rate environments, dividend reinvestment often happens at disappointing prices.

How to research the fund

Start with the fund’s prospectus and fact sheet on Calamos’ website, which spell out the exact selection criteria, the list of holdings, and the current expense ratio. The fund’s trailing returns and sector breakdown are readily available through any broker or financial data service.

To understand how SROI has performed relative to its broad peers, compare it to a traditional global dividend ETF or a global equity index fund without ESG constraints. Look at the composition — how much is in the United States, Europe, emerging markets — and the sector concentration. Watch the dividend yield relative to a comparable universe. The prospectus will detail the ESG criteria in full; reading it tells you what companies or sectors the fund refuses to hold, which is often more informative than what it claims to own.

The fund’s annual reports and SEC filings describe how the selection process actually works, what managers are wrestling with (currency hedging, sector tilts, dividend sustainability), and whether the ESG criteria are tightening or loosening over time. For investors considering the fund, a clear test is whether they believe both pieces of the puzzle — quality + ESG — will outperform a simpler strategy, and whether they are comfortable with the dividend tilt and its implications for growth capture.
