Timpani SMID Growth Fund (CTAGX)

Choose a class

Overview

The Fund invests in the equity securities of small and mid-capitalization companies with high, sustainable growth potential, which may exceed market expectations.

Key Features

Combines fundamental research with the analysis of estimate revisions to identify the underestimated growth differential between a company's business strength and market expectations of that strength.
Measures growth gaps to minimize two behavioral mistakes of growth investing: selling winners too early and not selling losers quickly enough.
Analyzes secular trends to uncover exploitable investment opportunities specific to small cap and mid cap companies.

Portfolio Fit

Investing in small and mid cap companies is an important component of a diversified investment strategy. Small and mid-sized companies tend to have a greater chance of growing rapidly and outperforming large-cap companies, yet this greater potential also raises the potential for greater volatility--which is why we believe active management is crucial to small and mid cap investing.

The Fund's investment advisor has contractually agreed to reimburse Fund expenses through March 1, 2022 to the extent necessary so that Total Annual Fund Operating Expenses of Class A shares and Class I shares are limited to 1.35% and 1.10% of average net assets, respectively. The Fund's investment advisor has contractually agreed to limit the Fund's annual ordinary operating expenses for Class R6 shares (as a percentage of average net assets) to 1.10% less the Fund's annual sub-transfer agency ratio (the aggregate sub-transfer agency fees of the Fund's other share classes divided by the aggregate average annual net assets of the Fund's other share classes). For purposes of these expense limitations, operating expenses do not include taxes, interest, short interest, short dividend expenses, brokerage commissions, acquired fund fees and expenses, and extraordinary expenses, if any. Calamos Advisors may recapture previously waived expense amounts within the same fiscal year for any day where the respective share class's expense ratio falls below the contractual expense limit up to the expense limit for that day. This undertaking is binding on Calamos Advisors and any of its successors and assigns. This agreement is not terminable by either party.
