High Income Opportunities Fund (CHYDX)

Choose a class

Overview

Through its multi-sector fixed income strategy, the fund invests mainly in high yield securities from U.S. issuers with the goal of generating a high level of current income and total return, which provides consistent excess returns above the benchmark over full market cycles.

Key Features

  • We construct the portfolio bond-by-bond with a focus on being well compensated for risks taken. We believe a disciplined process, grounded in fundamental research, enables us to achieve higher total returns with less volatility.
  • A broader investable universe enhances portfolio construction and risk management. Expanding the universe to include bank loans and preferred securities provides additional opportunities.
  • We conduct robust, independent credit research. Our fixed income investment process unites quantitative and qualitative analyses into historical and forward-looking models. The result is a credit rating reflective of where a company is heading.
  • We apply a macro overlay to capitalize on opportunities in misunderstood industries and sectors. The overlay acts as a risk control that also considers the business cycle, geopolitical factors, inflation and real rate expectations.

Portfolio Fit

The fund can complement investment grade credit exposure, providing attractive income and total return potential for more risk-tolerant investors.

Top 10 Holdings and Sector Weightings are calculated as a percentage of Net Assets. The tables exclude cash or cash equivalents, any government/sovereign bonds or broad based index hedging securities the portfolio may hold. Holdings and weightings are subject to change daily. Holdings are provided for informational purposes only and should not be deemed as a recommendation to buy or sell the securities mentioned.
Bond credit quality allocation reflects the higher of the ratings of Standards & Poor’s Corporation or Moody’s Investors Service, Inc. Ratings are relative, subjective and not absolute standards of quality, represent the opinions of the independent, Nationally Recognized Statistical Rating Organizations (NRSRO), and are adjusted to the Standards & Poor’s scale shown. Ratings are measured using a scale that typically ranges from AAA (highest) to D (lowest). The security’s credit rating does not eliminate risk. The table excludes equity securities, cash and cash equivalents. For more information about securities ratings, please see the Fund’s Statement of Additional Information at calamos.com. Additional information on ratings methodologies are available by visiting the NRSRO websites: www.standardandpoors.com and www.moodys.com.
Annualized standard deviation is a statistical measure of the historical volatility of a mutual fund or portfolio, computed using 5-year returns. Average effective duration provides a measure of the Fund’s interest rate sensitivity—the longer a fund’s duration, the more sensitive it is to shifts in interest rates. Beta is a historic measure of a portfolio’s relative volatility, which is one of the measures of risk; a beta of 0.5 reflects half the market’s volatility as represented by the strategy’s primary benchmark, while a beta of 2 reflects twice the volatility. Option adjusted spread (OAS) is the yield spread which has to be added to a benchmark yield curve to discount a security’s payments to match its market price; uses a dynamic pricing model that accounts for embedded options and is usually measured in basis points. 30-Day SEC yield reflects the dividends and interest earned by the Fund during the 30-day period ended as of the date stated after deducting the Fund’s expenses for that same period. Yield-to-worst is the lowest potential yield that can be received on a bond without the issuer actually defaulting.
