CAGEBCalamos Autocallable Growth ETF

IDUBBAptus International Enhanced Yield ETF

In short

CAGE Autocallable payoffs, ETF-wrapped. CAGE holds a laddered book of long-dated autocallable growth options tied to a US large-cap index (MQUSLVA), with no income target and no distributions: the whole case sits in the share price.

IDUB Income-overlay funds usually stop at the U.S. border. IDUB goes the other way: an actively managed developed-plus-emerging-markets stock sleeve with a growth and momentum tilt, built to out-yield MSCI AC World ex USA, for 0.44% a year.

Stated mandate

CAGE CAGE seeks long-term capital growth with reduced downside risk through a laddered portfolio of synthetic autocallable growth options linked to the MerQube index. Coupons are reinvested rather than distributed.

IDUB The Fund seeks capital appreciation together with current income.

Why people hold it

  • CAGE Unusual mandate: a laddered stack of long-dated autocallable growth options on a US large-cap index, held synthetically rather than as shares.calamos.com
  • Fees run 0.74%, a hair under the 0.75% median for options-overlay funds, though cheaper overlay peers exist (LQDW at 0.34%, YLDE at 0.47%).
  • Exposure is pinned to a named third-party benchmark, MerQube's US Large-Cap Vol Advantage Index (MQUSLVA), not a discretionary trading book.calamos.com
  • IDUB Rare address for an income-overlay fund: developed and emerging market stocks, with the income goal set against MSCI AC World Index ex USA instead of a U.S. benchmark.
  • Charges 0.44% a year, well under the typical fee in its options-income peer group.
  • Actively managed with an advertised growth and momentum screen, so the stock side is a selection decision, not a market-cap copy of the index it's measured against.
  • Pairs capital appreciation with current income in one mandate, and lands among the stronger implementations in its options-income cohort.

Worth knowing

  • CAGE Launched in 2026, so there is no multi-cycle record behind it yet and less history to judge the strategy against.
  • You hold an options package, not the underlying companies, so outcomes follow the index rules and options pricing rather than a basket of stocks.calamos.com
  • Growth-only by design: the fund declares no income target and no distribution schedule, so nothing arrives as cash.calamos.com
  • IDUB Income is defined relative to the benchmark's yield, not a fixed payout, so the quarterly distribution moves around and can include return of capital.
  • Trades thinly next to the headline U.S. income ETFs, which can mean wider spreads on busy days.
  • Going abroad adds currency moves and emerging market country risk that a U.S.-only income fund doesn't carry.
