Our read on each fund
GIAXD
IDUBB
In short
GIAX Most income ETFs sell calls on the stocks they hold. GIAX runs a global equity core plus daily credit call spreads on US indices, where a further-out long call caps each short. Income first, paid monthly.
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
GIAX The actively managed ETF primarily seeks current income and secondarily seeks capital appreciation. It combines global-equity exposure through passive ETFs or representative securities with daily index credit call spreads and Treasury or cash holdings.
IDUB The Fund seeks capital appreciation together with current income.
