The Funds investment objective is to seek to track the performance of the Calvert US Large-Cap Core Responsible Index (the Index), which measures the investment return of large-capitalization stocks.
The fund tracks the Calvert US Large-Cap Core Responsible Index using a replication method, holding the common stocks of large-capitalization U.S. companies that meet environmental, social, and governance criteria under the Calvert Principles, weighted by float-adjusted market capitalization. Because the fund is subject to regulatory diversification and concentration limits that the Index is not, its holdings may materially deviate from the Index it seeks to track.

How it has done
CSXAX share class · total returns with dividends reinvested
Volatility over the last 12 months: 14.36%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
The 4 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.49% | +30.14% | +85.72% | +80.39% | -9.66% | |
| 1.24% | +29.17% | +81.58% | +73.79% | -9.83% | |
| 0.24% | +30.49% | +87.12% | +82.74% | -9.61% | |
| 0.19% | +30.55% | +87.38% | +83.14% | -9.59% |
These classes hold the same portfolio, so the 9.35pp spread over 5 years is the cost difference between them — roughly 1.87pp a year — not a difference in what they own.
