CALAMOS INTERNATIONAL GROWTH FUND (CIGRX)

Choose a class

Overview

The fund invests in non-U.S. growth companies, focusing on those firms demonstrating what we believe to be key growth characteristics, including increasing profit margins and high returns on invested capital.

Key Features

  • Focus on growth in an asset class that is mostly defined by core and value offerings
  • Stress company fundamentals, including global presence and strong and/or accelerating earnings growth
  • Investments driven by international sources of revenue for companies, not on location of headquarters

Portfolio Fit

Only about 10% of international stock assets are currently invested in growth. The fund stands as a potential growth-focused addition to a mostly core- or value-intensive international allocation.

Active, High-Quality Growth Investing

In focusing on companies that we believe possess key growth characteristics, such as strong revenue growth and greater access to capital, the fund maintains a far more growth-focused investing style than that of its peer group, as seen in this holdings-based style map.

Before investing carefully consider the fund's investment objectives, risks, charges and expenses. Please see the prospectus and summary prospectus containing this and other information or call 1-800-582-6959. Read it carefully before investing.

Beta-Is a historic measure of a fund's relative volatility, which is one of the measures of risk; a beta of 0.5 reflects 1/2 the market's volatility as represented by the S&P 500 Index, while a beta of 2.0 reflects twice the market's volatility.

Large-cap foreign stocks have market capitalizations greater than 5 billion. Growth is defined based on high price/book and price/cash-flow ratios, relative to the MSCI EAFE Index.

Important Fund Information

  • Calamos Growth, Growth and Income, Opportunistic Value, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest in small and mid-size company securities, which generally present greater risk and higher volatility than investments in larger, more established companies.
  • Calamos Growth, Growth and Income, Opportunistic Value, Focus Growth, Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds invest a substantial portion of their assets in equity securities, which are subject to greater fluctuations in market value than other asset classes as a result of such factors as a company's business performance, investor perceptions, stock market trends, and general economic conditions.
  • Calamos Global Growth and Income, International Growth, Global Equity and Evolving World Growth Funds may invest up to 100% of assets in foreign securities. Total Return Bond Fund may invest up to 35% and all other Calamos funds up to 25% of assets in foreign securities. Investing outside the U.S. offers both risks and rewards. Increased volatility, changes in the value of foreign currencies, and difficulty in obtaining information are some of the risks involved.
  • Global Growth and Income, International Growth, Global Equity, Evolving World Growth and Total Return Bond Funds may invest in securities issued by companies in emerging markets; these may present additional risk due to the potential for greater economic and political instability in less developed countries.
  • Calamos High Income Fund invests and Total Return Bond Funds may invest in lower-rated fixed-income securities, often referred to as "junk bonds," which generally present greater risks than higher-quality securities, because of the greater likelihood that the company issuing the lower-rated securities will default on income and principal payments.
  • Calamos Growth and Income, Convertible and Market Neutral Income Funds: There are certain risks associated with an investment in a convertible bond such as a default risk—the company issuing a convertible security may be unable to repay principal and interest—and interest rate risk—the convertible may decrease in value if interest rates increase.
  • Calamos Market Neutral Income Fund engages in short sales. Short sales involve the risk that the Fund may incur a loss if the market value of a borrowed security increases between the date of the short sale and the date the Fund replaces the security. A short position in a security poses more risk than holding the same security long. Because a short position loses value as the security's price increases, the loss on a short sale is theoretically unlimited. It is possible that the market value of the securities the Fund holds in long positions will decline at the same time that the market value of the securities the Fund has sold short increases, thereby increasing the Fund's potential volatility. The Market Neutral Income Fund engages in short sales of convertible securities' underlying stock, which may increase volatility and portfolio turnover.
  • Calamos Total Return Bond Fund may invest in derivative securities, including options, futures contracts and swap agreements. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. There is no assurance that any derivative strategy used by the Fund will succeed.
  • In addition to market risk, there are certain risks associated with an investment in Calamos Total Return Bond Fund, such as default risk, the risk that the company issuing debt securities will be unable to repay principal and interest, and interest rate risk that the security may decrease in value if interest rates increase.

Performance of the Growth Fund reflects the effects of an expense reimbursement that improved results and was in effect until March 31, 2000.

Performance shown for the Convertible Fund and Global Growth and Income Fund includes the effects of an overpayment of dividends and/ or capital gains distribution to shareholders of certain classes of shares of the Fund (and a corresponding capital contribution by Calamos Advisors LLC), which increased certain return figures.

1Net asset value is the $U.S. value of a single share excluding any sales charges. NAV Change shows the change in value from the prior business day: + = gain; - = loss; NC = no change. The net asset value of a fund will fluctuate. Please note that total return is considered one of the best measures of overall performance of most mutual fund investments. More complete information and long-term performance is available for each Fund by clicking on any Fund name. Shares are redeemable at current net asset value, which may be more or less than their original cost
